Due to the wide use of cement mortar and cement concrete the cost of building materials increasing very quickly in some parts of the world also in developing country like India so only the industries, business cooperation, government and few individuals can afford it. This rising cost can however be reduced by use of alternative building materials that are locally available and cheap. Some industrial and agricultural waste products may be used as building material. There are different wastes available in large quantities that have properties to make concrete and mortar such as fly ash, rice husk ash, blast furnace slag etc. i.e. geopolymer mortar and geopolymer concrete. The study begins with a detailed literature review on fly ash, rice husk ash, its chemical properties its bonding with mortar or cement and its feasibility in the construction industry focusing firstly on the nature of the scope of the construction industry and the most activities that involve cement mortar and cement concrete operations. Here we will talk about strength of Fly ash and RHA both with cement blending and without cement, environmental impact of cement and its reductions with using Fly ash and RHA.
