Improvement of concrete strength and durability are of great concern especially when the concrete is exposed to an aggressive environment. Considerable efforts are being taken worldwide to utilize local natural waste and by–product materials in making concrete, such as rice husk ash (RHA) as supplementary cementing materials to improve concrete properties (strength, durability, etc.). Hence an attempt has been made in the present investigation on replacement of cement with rice husk ash up to 20%. In present investigation, the grade of concrete M30 and M60 mixes has been taken as reference concrete and to find out the mechanical properties and some durability characteristics. In general the properties of rice husk ash concrete are higher than the controlled concrete. From the experimental study it has been observed that the RHA based concrete reduces permeability property of concrete compared to control concrete specimens.
