Abstract
Concrete is most used construction material worldwide in the construction industry. Use of the concrete in the construction world is going high day by day. With the increasing urbanization the demands of the people are also increasing which is putting more pressure on the natural resources which are depleting day by day. On the other hand, the construction waste is increasing at drastic pace, which is currently dumped as waste in the landfills. In this research work, efforts had been made to utilize the waste .Production of cement also produces enormous amount of the greenhouse gases. Rice husk ash (RHA) which also shows the cementious properties has the potential to be used in production of concrete as replacement of cement. This study covers the utilization of recycled aggregates in place of cement and RHA as a replacement of cement in the production of concrete. Their utilization in the concrete shows that the both can be used as alternate material for the concrete production paving the path to sustainable development. This study will help the construction industry to enhance the potential to use such waste in the construction.
