Abstract: In this paper, the effects of fine aggregate type on consistency, capillary water absorption and compressive strength were evaluated for cement mortars blended with 0%, 10%, 20%, 30%, and 50% biomass ash, by mass. Following types of fine aggregate were varied: standard quartz sand, fractionated aggregate of river origin - fraction 0-4mm and sand for plastering of river origin. The ash generated by combustion of mixture of wheat and soya straw (1:1, by mass) was used as a SCM. The results indicate that it is possible to produce mortar, with 30% of biomass ash, with physical and mechanical properties comparable with those of reference mortar.
