(2018-06-21T06:33:48Z) Kalyani, S; Narla Hari Prasad, Reddy; Nayana Reddy, R; Are, Saichand
The main objective of this research is to investigate the possibility of utilizing waste steel slag in concrete production. In this project experimental investigation conducted on optimum steel slag replacement with fine aggregate. After the formation of by-product steel slag, in large amount from steel industries. This steel slag is disposed to open land area, it makes land pollution and harmful to environment. It has good physical parameters and gives enough strength to concrete and due to this it is suitable to bear heavy load. In further study fine aggregate is replaced by steel slag, and then concrete is prepared. The replacement ratio which have been studied were, 20%, 40%, 60%, 80%, and 100% by weight. Water–cement ratio kept 0.34. Concrete made with steel slag as fine aggregate replaced achieved better performance compared to normal concrete. Physical properties of conventional concrete and fine aggregate replaced concrete are compared. On fresh concrete slump test was preformed to check workability of concrete and after then compressive strength and flexural strength was checked. Thus steel slag is appropriate substitute of fine aggregate in concrete mix for construction.
Comparative Study on Structural Parameter of RCC and Composite Structures
(2018-06-21T06:44:39Z) Basavaraj S, Bachihal; C M Lakshmi Narayana, Kanth; Hemanth, D R; Lakshman, K
In today's modern era of innovation, two materials widely and inevitably used as construction material are steel and concrete for structures ranging from buildings to bridges. Though these materials may have different properties and characteristics, they both seem to complement each other in many ways. Steel has excellent resistance to tensile loading but lesser weight ratio so thin sections are used which may be prone to buckling phenomenon. On the other hand concrete is good in resistance to compressive force. Steel may be used to induce ductility an important criteria for tall building, while corrosion protection and thermal insulation can be done by concrete. Similarly buckling of steel can also be restrained by concrete. In order, to derive the optimum benefits from both materials composite construction is widely preferred
Compatibility and Efficiency of Superplasticizer and New Generation Superplasticizer with Different Brands of Cement
(2018-06-21T07:07:56Z) Adarsh, L D; Madhu Patel, N V; Manoj, R; Shivanand, Patil
In order to meet the performance requirements of the concrete for various infrastructure projects, concrete mixers have to be designed and produced using combinations of different cementitious materials with water and aggregate and chemical admixtures. The active constituent of concrete is cement paste and largely it determines the performance of the cement paste, also setting time acceleration or retardation can be achieved by the use of admixtures. In addition of some particular admixture may develop undesirable interaction between varying ingredients of concrete. Many times addition of admixture beyond the certain limit may show incompatibility. The constituent materials of making concrete confirm to Indian standard specifications, but different types of cement vary from batch to batch and brand to brand in there chemical composition. Therefore in this study the compatibility of a chosen admixtures (Auromix 200, Master Glenium sky 8341, Master Rheobuild 1126 N D and Master Glenium sky 8233) with different brands of 53 grade ordinary Portland cement ( ACC cement, Birla Super cement, Dalian cement, Ramco cement and Maha cement ) have been determined by optimum dosage and efficiency of admixtures by marsh cone test.
A Study on Bacterial Concrete
(2018-06-21T07:28:31Z) Sandhya, MG; Radhika, S; Savitha, R
Concrete is a construction material that is used world-wide because of its first-rate properties. However, the drawback of this material is that it easily cracks due to its low tensile strength. It is a well-known fact that concrete structures are very susceptible to cracking which allows chemicals and water to enter and degrade the concrete, reducing the performance of the structure and also requires expensive maintenance in the form of repairs. In this paper, the following notable points regarding classification of bacteria, selfhealing of cracks in concrete, chemical process for crack remediation, self-healing mechanism of bacteria, application of bacteria in construction field, Advantages and disadvantages of bacterial concrete etc., are observed and identified from the other research works. Cracking in the surface layer of concrete mainly reduces its durability, since cracks are responsible for the transport of liquids and gases that could potentially contain deleterious substances. On the other hand the concrete structures show some selfhealing capacity, i.e. the ability to heal or seal freshly formed micro-cracks. When micro-cracks growth reaches the reinforcement, not only the concrete itself may be damaged, but also corrosion occurs in the reinforcement due to exposure to water and oxygen, and possibly CO2 and chlorides too. Self-healing of concrete can be done by many ways such as application of specific calcite precipitating bacteria for concrete repair, usage of synthetic polymers such as epoxy treatment, biomineralization of bacteria in concrete etc.,

(2018-06-21T07:37:39Z) Bimal, Shah; Vivek, Shah; Mukesh kumar, Yadav; Krishna kumar, Sah
The 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 is used at varying percentages ranging from 5%, 10%, 15% & 20% and Lime is kept constant to 6% in the test. Then the results and graphs of various mixes are compared to see their effects in sub grade stabilization. The stabilization technique has an additional benefit of providing an environment friendly way to deal with industrial waste (copper slag) with lime.

Due to scarcity of petroleum and coal it threatens supply of fuel throughout the world also problem of their combustion led to research in different corners to get access the new sources of energy, like renewable energy resources. Solar energy, wind energy, different thermal and hydro sources of energy, biogas are all renewable energy resources. But, biogas is distinct from other renewable energies because of its characteristics of using, controlling and collecting organic wastes and at the same time producing fertilizer and water for use in agricultural irrigation. Biogas does not have any geographical limitations nor does it requires advanced technology for producing energy, also it is very simple to use and apply
Biogas Production from Anaerobic Digestion using Sewage Sludge
(2018-06-21T07:59:43Z) Adel, Jeelani; Khalid, Ajaz; Kumar, Shivankar; R K, Pintu
Biogas production requires anaerobic digestion. The anaerobic digestion of kitchen waste produces biogas, a valuable energy resource. Anaerobic digestion is a microbial process for production of biogas, which consists of primarily methane (CH4) & carbon dioxide (CO2). It is further facilitated by addition ofinoculum i.e. sewage sludge. The wastes produced in the college premises is dumped which is not utilized and proves to be a nuisance to the environment. Hence this waste was used for biogas generation. Preparations were for the installation setup where the generation of biogas was measured and different laboratory tests were carried out. The continuously-fed digester requires addition of sodium hydroxide (NaOH) to maintain the alkalinity and pH to 7. The digester was seen to have a temperature of 30°C mesophilic range

(2018-06-21T08:09:12Z) Aditya, A; Avinash, C; Dheeraj, P.A; Srivatsava, K
The black cotton soil possess less stability, less shear strength and large expansion and shrinkage in volume with changing seasons. Hence, we must increase the compressive strength of black cotton soil with the use of quick lime and polypropylene. Black cotton soil occupies nearly 23% of the area in India is a problematic soil, available up to a depth of 3.7 meters on a average. Innovative methods of soil stabilization are in great demand all over the world. The demerits obstruct construction like big infrastructure, road pavement, etc. on the soil. These soils cause more extensive damage than even natural disasters.

(2018-06-21T09:00:57Z) Amrutha Lakshmi, B.M; Apoorva.M., Reddy; Charan, .R; Darshini.P., Naik
Since globalization, day by day construction activities have enormously taken place. The raw materials used for making concrete have become an acute shortage, especially aggregates. In the present study, we have made an attempt to replace natural crushed coarse aggregate by cinders, which is a by-product of steel manufacturing industry in slag based concrete blocks. Blocks of size 400*200*150mm are chosen and mix proportion is selected as per IS: 2185 i.e., 1:4:8 and w/c is 0.6. The blocks were casted by replacing (0%,20%,40%,60%,80%, & 100%) natural crushed coarse aggregate by cinders using concrete block making machine (egg laying machine), and cured for 28 days. After curing, the blocks were tested to know the mechanical properties such as compressive strength, modulus of elasticity and water absorption. From the results obtained, 20% replacement is found to be suitable in terms of strength development, water absorption and modulus of elasticity.

(2018-06-21T09:07:41Z) B R Bheema, Reddy; Charan, U T; Darshan, A M; V, Goutham
Construction and demolition waste constitute one of the major components of waste generated worldwide. Very large quantities of aggregates are used in construction. When the useful life of the structure is over it will be demolished and all the demolished wastes just find their way to landfills. Finding large areas for landfills is becoming very difficult. On the other hand continuous extraction and quarrying of natural aggregates for construction is causing depletion of natural resources. The recycling of demolished construction waste aggregates to be used in new engineering application provides a promising solution to both problems. So in order to reduce construction cost and resolving housing problems faced by the low income communities of the India. This project/research includes an experimental study on concrete by taking partial replacement of coarse and fine aggregate with demolished waste to determine the compressive strength and flexural strength and results are compared with normal concrete

LIFE CYCLE COST ANALYSIS OF PAVEMENT (LCCA) is detail study of transportation project relating pavements starting from its design phase to its entire service life. It determine the total cost and value of item over the entire cycle along with pavement thickness and type. The cost of road construction includes design expenses, material extraction, construction equipment, rehabilitation and maintenance strategies. In this project a stretch of 24km national highway of BUTWAL, NEPAL was considered and various data like pavement performance, traffic, and climatic condition, economic indicators were collected and integrated. Flexible pavement was designed for design period of 10 year with maintenance of 15 years and was compared with rigid pavement designed for period of 30 years to finalize optimum performance of pavement based on pavement cost and strain, stress analysis. Based on above study we conclude that the initial cost of rigid pavement is 28% higher than the initial cost of flexible pavement but these costs get balanced during the entire 30 year life since more durability and serviceability is provided by the pavement

(2018-06-21T09:44:10Z) Bhavyashri, R; Deepika, B G; Gangamma, K; Vanitha, B
Concrete is strong in compression but weak in tension. As concrete is brittle material the failure in concrete due to tension is sudden. There are also cracks in concrete due to shrinkage and these micro cracks propagate and leads to failure. To safeguard the concrete against flexural cracks fibers are used in concrete section which is known as fiber reinforced concrete
Redesign of Storm Water Drains in Chinnappanahalli Kere Catchment
(2018-06-21T09:52:20Z) Archana, Gopinath; Dilip Kumar, G; Sai Somesh, V; Yadav, C R
With advent of housing developments, the canals were encroached upon and became drains. Lakes were filled up and became housing layouts. The drains were used as dumping ground for construction debris and solid waste from the housing areas. Canal systems which used to function very well transferring excess water downstream got interrupted and many low-lying areas got submerged even with a small flood. Thus, the rehabilitation of existing drains has assumed significance. The project identifies the deficiencies in the existing Storm water drains and also the measures to correct them. The entire catchment area is divided into sub catchments that form the designated units for data collection. The redesign of storm water drains is based on the principles of hydraulics to meet the required capacities, which is technically, economically, socially, legally and environmentally feasible.
