Abstract
Cement is an important construction material in concrete production; however, it is expensive and unaffordable for many low-income and rural communities in developing countries. In this experiment we replace the cement by rice husk (RHA) and fly ash(FA). In this experiment rice husk is constant i.e. 20% of weight of cement and fly ash is varied i.e. 5% ,10%and 15% by weight of cement. The study further satisfy that the RHA based concrete was more cost efficient in structures that were close to areas of rice production due to reduced RHA transportation costs.

Key word: Rice husk ash, expensive, construction, communities
