This paper presents the effects of using Rice Husk Ash (RHA) as a partial cement replacement material in mortar mixes. This work is based on an experimental study of mortar made with Ordinary Portland Cement (OPC) and 10%, 15%, 20%, 25% and 30% of OPC replaced by RHA. The RHA used was obtained from uncontrolled autocombustion of rice husk, in a chamber, without control of temperature and burning time. Sieve no 200 was used to sieved the ash and finally collect the passing ash. The mechanical properties investigated were the compressive strength, and also the porosity of mortar was tested. The obtained results show that the strength and porosity of mortar incorporating RHA were better, up to 20% of cement replacement level.
