Abstract
The infrastructure system is one of the main investment to every modern society for their economic and
social development, so demand for concrete is more and it is extensively used material for all construction activities.
There are different materials which are locally accessible and furthermore practical to acquire the best possible
quality of the concrete in development. By this significant demand for natural resources like sand etc., are consuming
day by day and heavy releases of carbon dioxide gas in cement manufacturing process, so in the recent years, global
warming and ecological and economical issues have become major problems. There is a need to identify suitable
alternatives for the production of Concrete. The use of industrial waste materials for concrete production has become
the latest trend in the research and construction industry. In this study an attempt has been made with a M20 grade
concrete. Experimental study is conducted to evaluate the mechanical properties of hardened concrete. Properties of
concrete have been assessed by partially replacing cement with Fly-Ash and sand with waste foundry sand. The
cement has been replaced by Fly-Ash in the range of 10%, 30% and 50% by weight of cement. The sand has been
completely replaced by Waste foundry sand. Concrete cubes were casted and tested after 7 days and 28 days of curing
period.
