Experimental Testing of Aerated Building Types using Gypsum, Copper Slag and Fly Ash

Construction industry is very essential for infrastructure development. Thus the needs of building Types are in keep on increasing. In India industrial by-products like Fly ash-50 million tons, copper slag-24.6 million tons and gypsum-5 million tons are produced each year and causes serious storage and environmental problem. The utilization of these industrial by-product materials is important in terms of environmental and economical issues are concerned. The study was made to evaluate the technical possibilities of incorporating fly ash, copper slag and gypsum in production of building Types. Various mixtures were prepared by incorporating these industrial wastes with different weight proportion. The suitable mix proportion was founded as 1: 2: 2 (G: CS: FA) and the physical and mechanical properties of that specimen such as unit weight, compressive strength, flexural strength, tensile strength, dimensional stability, water absorption and efflorescence values were founded out. The results were compared with conventional building Types shows utilization of these wastes additives is not only for conservation of clay resources, but also an alternative solution to difficult and expensive waste disposal problems. The bricks produced with these bi-products were named as SPAASH bricks.
