Experimental analysis on modulus of elasticity of slag based concrete

Abstract

Based on present scenario construction industries adopt so many problems directly, the problem is mainly due to release of carbon dioxide in atmosphere, how to rectify this problem, researchers are doing research regarding this particular issue only, so many researchers are found that replacement of OPC as industrial waste gives the more eco-friendly. Industrial wastes like GGBS, Fly ash, etc. based on the laboratory work industrial waste like GGBS in concrete without any cement is getting the required strength after adding 3% lime in place of cement and that too with stone dust not with sand due to high silica content. This concrete is getting the target mean strength after 90 days of curing. At 50% replacement of sand with stone dust shows better results than other proportions. This concrete is not that much workable when compared with conventional concrete as silica content more in this. This concrete absorbs more water as it is full of waste material; this is the main reason for not getting required workability. Elastic behavior is also good for this concrete and that too more at 50% stone dust. Elastic behavior of this slag based concrete depends upon proportion of stone dust as FA in this concrete. Modulus of elasticity of this concrete decrease with decrease of stone dust content in the concrete.
