Waste which is increasing day by day becomes eyesore and in turn pollutes the environment, especially in villages on the top of mountains, where no garbage collection system exists. The production of cement depletes natural resources, consumes high energy and emits huge amount of greenhouse gases. It accounts for 7% of the global carbon dioxide emission, as the production of one ton of ordinary Portland cement releases approximately one ton of carbon dioxide. Due to severe environment pollution and health hazards associated with the cement and construction industries, they are strict scrutiny from the government and environmentalists. Rice husk is an agricultural waste, whose natural degradation is restricted due to irregular abrasive surface and high siliceous composition, it is not appropriate to be used as a feed for animals due to the low nutritional values. If dumped as landfill, they can take a lot of area and become a major challenge to the environment. The use of RHA and glass fibre is found durable, environment friendly and economically viable. Studies suggest there is scope of usage of RHA and glass fibre in cementitious material. RHA is having good strength and high silica content while glass has similar chemical composition as that of sand, glass also has high tensile strength and good fire resistant property the addition of these materials will definitely provide us great concrete
