Item Comparision Study of Aluminium and Conventional Formwork Technology(2017-08-16T13:05:25Z) Harish Kumar, M B; Kavitha, K; Vishwas, G RFormwork is undeniably the key ingredient of concrete construction project, It is used to provide proper shape and support to concrete, until it gains sufficient strength to carry its own weight.it plays an important role in strengthening the concrete construction. Generally formwork cost around 35% of total cost of structure but it involves approximately 60% of project time. It is more beneficial to select formwork method cost during the designing phase of structure as then it can be included with cost of concrete and reinforcement. As formwork governs cost, quality and time. It is very important to choose a right type of formwork for the project. The project mainly concentrates on the study of Aluminum form work technology, and to compare it with conventional form work on the bases of cost, time cycle, and concrete used in form work.Item Optimisation of RCC Members in A G+5 Storey Structure by Using Light Weight Blocks(2017-08-16T13:01:22Z) V, Harini; Niladro, Roy; Subharanil, RoyRegular concrete blocks are one of the most important building materials in the India.

The constituents of concrete are coarse aggregate, fine aggregate binding material and water. Rapid increase in construction activities leads to acute shortage of conventional construction materials and increase in cement cost. In the backdrop of such a bleak atmosphere, there is large demand for alternative materials. Hence we are trying to use the limestone dust as an alternative material to partially replace the cement. This experimental study presents the variation in the strength of concrete when replacing cement by lime stone powder by 0% to 15% for preparation of M40 grade of concrete are taken into the study. The compressive strength of concrete cubes at age of 7, 14 and 28 days is obtained at room temperature. Split tensile strength of concrete are found at the age of 7 and 28 days. From the test results it is found that the maximum compressive strength, tensile strength is obtained only at 10% replacement. This result gives clear picture that lime stone powder can be utilized in concrete mixtures as a good substitute for cement at 10% replacement.Item Partial Replacement of Cement with Sugarcane Bagasse Ash(2017-08-16T12:43:09Z) Naveen, S N; Rakshith, E; Harish, MWe are aware that environment is affected drastically by manufacture of cement. It involves lot of carbon emission associated with other chemicals. The researches has shown that every one ton of cement manufacture releases half ton of carbon dioxide, so there is an immediate need to control the usage of cement. On the other hand materials wastes such as Sugar Cane Bagasse Ash is difficult to dispose which in return is environmental Hazard. The Bagasse ash imparts high early strength to concrete and also reduce the permeability of concrete. The Silica present in the Bagasse ash reacts with components of cement during hydration and imparts additional properties such as chloride resistance, corrosion resistance etc. Therefore the use of Bagasse ash in concrete not only reduces the environmental pollution but also enhances the properties of concrete and also reduces the cost. It makes the concrete more durable. This project mainly deals with the replacement of cement with Bagasse ash in fixed proportions. The concrete mix designed by varying the proportions of Bagasse ash for 0%, 5%, 10%, 20% the cubes are been casted and cured in normal water for ages of 7, 14 and 28 days. The test result indicate that the strength of concrete increase up to 10% Sugar cane bagasse ash replacement with cement.Item Assessment of Ground Water Potential Zones in Lower Arvathy 2 Watershed, Bengaluru Urban Area Using GIS and Remote Sensing Techniques(2017-08-16T11:41:05Z) Sahana R, Reddy; Nandashree, D; Sanath, JoshiIncreased demand of water in different sectors and restriction of water resources, necessitate the assessment of groundwater potential zones. Present study is carried out to assess potential groundwater zone and to identify groundwater potential sites in the Lower Arkavathy-2 watershed, Bengaluru Urban District of Karnataka State due to acute shortage of potable water, using Remote Sensing (RS), Geographical Information System (GIS), Multi-Criteria Decision Analysis (MCDA) technique and Weightage Sum Raster Overlay Analysis (WSROA) technique.

The relative weights were assigned to different thematic layers using Analytical Hierarchical Process (AHP). While determining the weightage of the various parameters, expert opinions were taken and the artificial groundwater potential zones and suitable sites for groundwater recharge were deduced. In the present study, five categories of groundwater potential zones were identified viz. very poor, poor, moderate, good and very good according to their suitability of area for groundwater recharge purposes.Item Strength and Behavior of Cocrete Using Foundry Sand and Dust(2017-08-16T11:36:47Z) Sachin, Gowda G; Gururajashekar, H; Manoj, YMetal foundries use large amount of sand as part of the metal casting process. Foundries successfully recycle and reuse the sand many times in casting process. When the sand can no longer be used in the foundry,it is removed from the foundry and is termed as “Foundry Waste Sand”. Like many waste products, foundry sand has beneficial application to other industries. Foundry sand consists primarily of silica sand, coated with thin film of burnt carbon, residual binder (Bentonite,sea coal, resins) and dust. Foundry sand and dust can be used in concrete to improve its strength and other durability factors.Foundry dust can be used as partial replacement of cement & foundry sand as partial replacement of fine aggregate or total replacement of fine aggregate and as supplementary addition to achieve different properties of concrete. In the present work,experimental investigation were performed to evaluate the comparative study of the properties of fresh & hardened concrete containg ferrous & non ferrous foundry waste sand as fine aggregate replacement. Fine aggregate were replaced with four percentage of foundry sand. The percentage of replacements were 0,33,66 & 100% by weight of fine aggregate & the percentage of replacement of cement by foundry dust were 0,5,10 & 15% respectively. Tests were performed for all replacement levels of foundry sand for M20 grade concrete at different curing periods (3, 7 & 28 days) KEYWORDS: Bentonite Clay, Ferrous and non ferrous.Item Effects of Fly ash and Charcoal on the Properties of Roller Compacted Concrete(2017-08-16T11:33:32Z) Rupa, B S; Naveen Kumar, K NDevelopment of the roller-compacted concrete (RCC) technology in the 1980s is considered by many as a significant breakthrough in the construction industry.

Experimental work was carried out to investigate the effect of replacing cement with metakaolin and flyash partially and keeping same water cement ratio. Mathematical model used in the succeeding section for evaluation of partial safety factors corresponding to varying reliability indices, for concrete mixes, takes into account the variations in the water cement ratio and percentage replacement of cement by metakaolin and fly ash. In the present study, Reliability based partial safety factors for compressive strength of concrete with partial replacement of cement by flyash and metakaolin have been developed considering the strength as a random variable. The compressive strength of concrete depends upon the properties of its constituent materials viz. cement, fine aggregate, coarse aggregate and mineral admixture such as flyash and metakaolin etc. In the present investigation, step by step procedure has been suggested to find out the partial safety factor.Item Monitoring of Air Pollution in and Around Bangalore City(2017-08-16T11:24:12Z) Rajesh, Chand; Rakesh, Kumar; Dipesh, ChaudaryThe rapid growth in motor vehicle activity is the challenges to overcome in urban areas in Bangalore during the last and this decade.

Instead, the source of materials such as GGBS, that are rich in Silicon (Si) and Aluminium (AI), are activated by alkaline liquids to produce the binder. This thesis reports the details of development of the process of making GGBS-based pervious Geo-polymer concrete. To activate the Silicon and Aluminium content in GGBS, a combination of sodium hydroxide solution and sodium silicate solution was used. Glenium B-233, superplasticizer was found to be useful to improve the workability of fresh GGBS based pervious Geo-polymer concrete, as well as the addition of extra water. The ratios of sodium silicate to sodium hydroxide and also the molarity of sodium hydroxide are varied and the compressive strength of hardened GGBS-based ambient cured pervious Geo-polymer concrete is calculated.Item Study on Pervious Concrete with Varying Percentage of Fine Aggregate(2017-08-16T11:13:50Z) Mohan, V G; Naveen, K A; Rajesh, KosuriThe beneficial properties of pervious concrete on storm water control, ground water recharging and recharging the local aquifers are well understood. As the use of pervious concrete becomes more prevalent throughout the world, the issue of constructability will become more of a concern. A number of practices exist to place pervious concrete, without any theoretical underpinnings or correlation to laboratory scale studies. This paper describes the current state of practice in ordinary Portland cement pervious concrete(OPCPC) placement and also presents results of OPCPC to determine a filed level QC/QA check for OPCPC. Test cubes are placed using a variety of techniques currently employed forfield placement of OPCPC. The results show that OPCPC samples with various voidshaving 7, 14 and 28 day compressive strengths and permeability tests. Test values are obtained from OPCPC have been shown suitable for pervious concrete applications as for the safety and strength. Our study shows that varying of fine aggregates samples with 0%, 12% and 24% with replacing coarse aggregates. The constructing technology of OPCPC is evolving, but the correlation between laboratory and field placement will allow standard QC/QA checks to be developed for producing permeable, strong, durable, and long-lasting pervious concrete.Item Steel Fiber Reinforced Concrete(2017-08-16T10:59:09Z) MD Arshad, Ahmed; Mohammed Ejaz, Akhter; Sivasheesh Sarat, DasConcrete is most widely used construction material in the world due to its ability to get cast in any form and shape. It also replaces old construction materials such as brick and stone masonry. The strength and durability of concrete can be changed by making appropriate changes in its ingredients like cementitious material, aggregate and water and by adding some special ingredients. Hence concrete is very well suitable for a wide range of applications. However concrete has some deficiencies as listed below: 1) Low tensile strength 2) Low post cracking capacity 3) Brittleness and low ductility 4) Limited fatigue life 5) Incapable of accommodating large deformations 6) Low impact strength The presence of micro cracks in the mortar-aggregate interface is responsible for the inherent weakness of plain concrete. The weakness can be removed by inclusion of fibres in the mixture. Different types of fibers, such as those used in traditional composite materials can be introduced into the concrete mixture to increase its toughness, or ability to resist crack growth. The fibres help to transfer loads at the internal micro cracks. Such a concrete is called fibre-reinforced concrete (FRC). The introduction of the paper should explain the nature of the problem, previous work, purpose, and the contribution of the paper. The contents of each section may be provided to understand easily about the paper.Item Influence of Geofrid and It's Position on Strength of Weak Subgrade Soil(2017-08-16T10:54:27Z) Drakshayini, N; Fazil, Ahammed; Haritha, MWeak subgrades are a common problem in road construction. Whether it is a temporary access road or a permanent road built over a weak subgrade, a large deformation of the subgrade can lead to deterioration of the paved or unpaved surface. Ground movements caused by swelling /shrinkage of expansive clays poses a threat to any structure resting on such clays. The performance of paved and unpaved road pavements constructed over such expansive soil subgrades is often poor and shows cracking, rutting and differential settlements/ heaving at various locations. Geosynthetics help to distribute the loads more efficiently and increase the effective bearing capacity of the subgrade, hence providing a better alternative to costly conventional stabilization methods. In this study an attempt has been made to stabilize the black cotton soil by introducing a single layer biaxial geogrid. Geogrid has been placed in different location and CBR test was carried out to analyse the effect of reinforcing layer and its position on CBR value of the soil. The obtained results showed that there was an increase in UCS and CBR with the introduction of geo grid reinforcement in layers and optimum position obtained from the study. From the study it has concluded that increase in number of layers increases the strength of subgrade soil and it can be considered as one of the technique of Ground improvement by means of reinforcementsItem Non Destructive Testing of Concrete in Structures(2017-08-16T10:50:26Z) Chiranth, P L; Mohammed Owais, Quraishi; Shanil, ParambathThe basic method of verifying whether concrete complies with specification is to test its strength using cubes or cylinders made from samples of fresh concrete. It must be noted that non-compliance by a single test specimen or even by group, does not necessarily mean that the concrete from which the test specimens have been made is inferior to that specified; the engineer‟s reaction should be to investigate the concrete further. This necessitates Non-Destructive tests on the concrete in the structure. Nondestructive testing methods have been used on civil engineering structures such as dams and bridges since the 1960‟s. In NDT, the development has taken place to such an extent that it is now considered as a powerful method for evaluating existing concrete structure with regard to their strength, durability, investigation of crack depth, micro cracks and progressive deterioration are also studied by this method. The aim of the present paper is to describe, how the NDT is done using ultrasonic pulse velocity for assessing concrete strength that are widely used in structural field. The main purpose of this test is to detect and identify defects in materials, measure its dimension and estimate its strength as well as to decide whether it is to be accepted or rejected.Item Soil Stabilization Using Industrial Waste and Lime(2017-08-16T10:46:18Z) Bidyashwor, Thokchom; Birendra, Bist; Om Prakash, YadavThe project deals with stabilization of soil using industrial waste. Unsuitable highway sub grade soil requires stabilization to improve its properties. Industrial waste such as copper slag is removed from the industry and is termed as industrial waste sand. Ingredients used are Copper slag, and lime. Copper slag is a by product of Copper industry. Lime was bought from locally available chemical laboratories. The project are planned to conduct various experiment like Specific gravity, sieve analysis, proctor compaction test, unconfined compressive strength and CBR test to increase strength properties and behaviour of sub base. Copper slag and lime are used at varying percentages ranging from 5%,10%,15% and 20% and 2%,4%,6% and 8% in the test. Then the results and graphs of various mixes are compared to see their effects in sub base stabilization. The stabilization technique has an additional benefit of providing an environment friendly way to deal with industrial waste (copper slag) with lime.Item A Parametric Study on Transmission Line Towers due to dynamic Loading(2017-08-16T10:43:04Z) Ashok Kumar, Bhakta; Shivaram Brahmanand, Nayak; Pinjara, AshabeeNow a days four legged lattice towers are most commonly used as transmission line towers. The present work describes the analysis and design of self-supporting steel transmission line towers viz four legged models using common parameters such as varying heights and different shapes of bracing system, with an angle sections system are carried out. In this constant loading parameters including wind forces as per IS: 802 (1995) are taken in account. The load calculations are carried out for normal conditions. The loading calculations on tower are due to conductor and ground wire in normal conditions as well as broken wire conditions considering transverse direction wind. The efforts have been made to do 3D analysis of tower considering all the members of the space truss as primary members. STAAD Pro has been used to analysis and designs the members of tower. A number of experimental configurations of the tower are obtained by increasing the heights of tower and also by changing the bracing patterns. After analysis, the comparative study is carried out with respective to slenderness effect, critical sections, forces and deflections of the towers.Item Evaluation and Comparative Study of Green Building and Conventional Building(2017-08-16T10:38:35Z) Allen Thomas, Varghese; Megha, Majumdar; Nikhil, SreenathA Green Building refers to the efficient use of energy flows. A Green Building is one which uses less water, optimises energy efficiently, conserves natural resources, generates less waste and provides healthier spaces for occupants as compared to a conventional building. A Green building, also known as a sustainable building, is a structure that is designed, built, renovated, operated or reused in an ecological and resource efficient manner. We compare these houses, bringing out the differences and benefits over the conventional buildings. The objective of the study is to incorporate the energy saving techniques and materials for a building to convert it into a green building, find out the percentage increase in cost while constructing a green home instead of a conventional home, find out a way to encourage green construction, and to compare the costs of construction between green houses and conventional houses. In this project, we are converting conventional villas into green buildings through various incorporations and comparing the cost aspects with conventional buildings. The results are outstanding as there will be environmental benefits, economic benefits and social benefits which helps people to stay in a better world.Item Recycling of Construction and Demolition Waste(2017-08-16T10:33:16Z) Ajay Kumar, Koyalmudo; Nikhil, S; Avinash, PThe project is based on the recycling of the rapidly increasing construction and demolition waste. Through this process we want to take a step ahead, the idea of stopping illegal sand mining, earth excavation and ultimately save our mother Earth from destruction. The cost of recycled sand and aggregates is lower than conventional aggregates and sand, resulting in reduction of overall construction cost. Our primary aim is to study in depth about the different properties of construction and demolition waste, perform various tests, so that the recycling processes can be designed accordingly for optimum efficiency. On the basis of these test results and projections we will get a rough estimation about the total quantity of recycled aggregate and recycled sand that can be obtained. Further with the help of the obtained recycled material we intend to use in construction based on their properties which will in turn be less costly as well. These recycled materials and products made from it are economical without any considerable change in the strength and durability aspect. Not only the cost effectiveness but it will also be aesthetically pleasing.
