Experimental Studies on Compressive Strength of Aerated Concrete with Varying Percentage of Aluminium Powder

Abstract

Today the disposal of various by-product materials is a concern against the environment, these are producing due to rapid industrial growth in our country. Most of the researchers are focused on the utilization of these by-products in the civil engineering construction industry. By using these by-products, on one hand, will protect the environment and other hands the disposal problem will be solved. Day by day the requirement of building materials increased due to urbanization, due to this more raw materials are required and depleted the natural resources. In this contest, environmental protection is need to protect incremental temperature in nature. To avoid these problems of the modern era, aggregation of these by-products can be used as one of building material and to overcome this situation, Aerated concrete is one of the solutions by reducing the raw material quantity in concrete like sand and cement by introducing air without compromising in the volume. Day to day aerated concrete has become popular due to lightweight and high insulation against temperature and sound. This concrete is using in high raised buildings to reduce the self-weight of building to protect during earthquake situations. In this experimental study mainly performed the compressive strength of aerated concrete with replacement of sand by quarry dust. Also reducing the cement content with replacement of fly ash, GGBS and lime powder at various percentages that is ranging. the performance of aerated concrete was observed more satisfactory when compared with and without replacement of above-saided materials.
