Experimental Study on the Use of Pond Ash and Walnut Shell in Concrete

The main objective of the present study is to find out a suitable, effective and alternative material for partial replacement of cement and coarse aggregate, to find out the possible utilization of waste materials in the construction industry that in turn considerably minimizes the usage of cement and coarse aggregate and ultimately reduce construction cost, to explore possibilities of improving mechanical properties of concrete using pond ash instead of cement and Walnut Shell instead of coarse aggregate partially, to evaluate the effect of using pond ash and Walnut Shell in concrete and to investigate the strength of replaced concrete with that of conventional concrete. This project is mainly undertaken to study the behaviour and performance of concrete using waste materials such as pond ash and Walnut shell. This type of use of waste material can solve problems of lack of aggregate in various construction sites and reduce environmental problems related to aggregate mining and waste disposal. The use of waste aggregates can also reduce the cost of concrete production and increase the workability.
