GEO-POLYMER OF BRICK BY USING RICE HUSK OF FLY ASH

As a result of booming infrastructural development around the world, the demand for cement production is increased. Ordinary Portland Cement (OPC) is mainly used as a cementations material for the concrete production. Nowadays, concrete industry is known to be the major consumer of natural resources, such as water, sand and aggregates, and manufacturing Portland cement also requires large amounts of each of them. The energy consumption for OPC production is high. It is estimated that the production of cement will increase from 1.5 billion tons in 1995 to 2.2 billion tons in 2010 (Malhotra, 1999). For manufacturing each tone (t) of the OPC about 1.5t of raw materials is needed (Mccaffery, 2002). The production of 1t of OPC consumes 4GJ energy and produces about 1t of carbon dioxide (CO2) to the atmosphere which leads to environmental pollution (Mehta, 2001). To reduce the environmental pollution and excess embodied energy utilization, one method of alternative solution can be Geo-polymer concrete.
