Abstract: This paper presents some preliminary results achieved within the scope of a research programme with the main objective of studying the effect of rice husk ash (RHA) particle size in lime based mortars. A Portuguese commercial RHA was used after being sieved and ground in the laboratory. The influence of the RHA particle size was assessed on fresh and hardened properties of lime based mortars. The results point out: the reactivity of the rice husk ash, the increase in the pozzolanic reactivity with the reduction of the RHA particle size and the possibility of improving lime mortars strength.
