Abstract

The aggregates and cement were replaced by the mixture of saw dust ash (5-12%) and coal dust (5-12%) respectively. The saw dust ash was used earlier for replacing the mixture of cement by maximum 25%. But in this project we are replacing the aggregate with saw dust ash and coal. Here as the surface area of the aggregate increases, the water demands increases and the strength of the concrete decreases. But the saw dust ash has less area as compared to that much volume of coal so it may increases the strength with the help of coal and cement. Our aim is to reduce the cost of construction attaining the strength by replacing the saw dust ash and coal dust by construction material. And after this we would find out the areas where the concrete (contain the saw dust ash and coal dust) can be used economically.
