High Volume Fly Ash Concrete

Dr. R. R Singh, Er Arpan Jot Singh Sidhu

Abstract :

Millions of tons of cement is used every year that adversely affects environment. Cement is also an important building material for infrastructure development. Cement can be suitably replaced with low cost and so called waste materials like fly ash favoring environment and saving cement. For a variety of reasons, the concrete construction industry is not sustainable. First, it consumes huge quantities of virgin materials. Second, the principal binder in concrete is portland cement, the production of which is a major contributor to green-house gas emissions that are implicated in global warming and climate change. Third, many concrete structures suffer from lack of durability which has an adverse effect on the resource productivity of the industry. Because the high-volume fly ash concrete system addresses all three sustainability issues, its adoption will enable the concrete construction industry to become more sustainable. So as a Civil Engineer we should effectively try to use fly ash in construction,as it helps in saving environment with reduced construction cost along with many other advantages, but now question rises to what extent or percentage fly ash could be used in concrete for construction works, and to answer this present study have been made. In this paper, a ief review is presented of the theory and the design of M40 concrete mixture containing 28%, 50%, 70% fly ash by mass of cementitious material. The compressive strength of 3, 7 and 28 days and flexural strength of 28 and 56 days of 28%, 50% and 70% fly ash content M40 concrete cubes and beam sample respectively are compared.
