    An Experimental Investigation on FaL-G Paste
    (2015-04-13T10:18:30Z) Niranjan, PS; Radhakrishna
    FaL-G is the product name given to a cementitious mixture composed of Fly ash (Fa), Lime (L) and Gypsum (G). It is low-cost and environmental-friendly material very useful in rural housing industry. Since it is manufactured using industrial wastes and by-products, the environmental impacts are mitigated. This paper addresses the technology of making compressed FaL-G paste blocks with low-calcium (Class F) dry fly ash procured from Raichur Thermal Power Plant, Karnataka and sponge iron plant Malur. The cardinal aim is to study the setting and strength characteristics of FaL-G paste. Its applicability as controlled low strength material is also ascertained. The FaL-G paste compressed cylinders were prepared without the use of conventional cement. The compressive strength of FaL-G cylinders were tested with different parameters. It was noticed that the strength of FaL-G paste increases with age and adequate to use it in making deferent composites. FaL-G paste can also be used as controlled low strength material as it has good relative flow area and adequate strength development with age.

    Fal-G Mortar Compressed Hollow Blocks
    (2015-04-13T10:29:41Z) Niranjan, P S; Radhakrishna
    FaL-G is the product name given to a cementitious mixture composed of Fly ash (Fa), Lime (L) and Gypsum(G). It is low-cost and environmental-friendly material very useful even in rural housing industry. FaL-G in certain proportions, as a building material is an outcome of innovation to promote large-scale utilization of fly ash. It gains strength like any other hydraulic cement in the presence of water and it is water resistant when hardened. This paper addresses the technology of making FaL-G mortar compressed hollow blocks with lowcalcium (Class F) dry fly ash as the base material. The FaL-G masonry hollow blocks were prepared without the use of conventional cement. Quarry dust and sand were used as fine aggregates as sustainable materials. The properties and compressive strength of FaL-G masonry hollow blocks were tested with different parameters. The experimental results reveal that the FaL-G hollow blocks are suitable to be used for the construction of masonry structures.

    Feasicbility studies of reusing of industrial waste water for irrigation
    (2011-11-11T06:59:42Z) Thippeswamy, H.N; Manjunath, NT
    This paper throws light on the results of experimentation carriedout to evaluate the feasibility of reusing industrial effluents and combination thereoffor irrigation to grow root crop radish. The parameters namely germination percentage, leaf numbers and plant height were considered for study. The impact of sugar mill and distillery effluents and their diluted combination with sewage, along with control irrigation (water) on the parameters selected are discussed in this paper. It was abserved that industrial effluent from sugar mill and distilleries and their diluted combination with sewage con be productively reused to grow radish. TDS and organic conteuts of waste water had significant influence on yield and growth.
