Abstract

Concrete is today the largest consumable material in the world that utilizes the natural resources such as sand, crushed stone and water. Due to the depletion of these natural resources for concreting, research is being carried out nowadays to reduce the consumption of these resources. Rapid development of construction in India has resulted in shortage of conventional construction material. In developed country like India use of concrete is higher quantity and availability of raw material is very less. The ceramic industry inevitably generates wastes, irrespective of the improvements introduced in manufacturing processes, in the ceramic industry; about 15%-30% productions goes as waste. In India during the milling of paddy about 78 % of weight is received as rice, broken rice and bran, the rest 22 % of the weight of paddy is received as husk, the 25 % of the weight of this husk is converted into ash during the firing process, which is known as rice husk ash (RHA). These wastes causes problem in present day society, requiring a suitable form of management in order to achieve sustainable Proper introduction of ceramic powder and rice husk ash in concrete improves both the mechanical and durability characteristics of the concrete. This paper present literature review on replacement of cement with rice husk ash and fine aggregate with ceramic powder which includes current and future
