Abstract

Wood waste ash is generated as a by-product of combustion in wood-fired power plants, paper mills, and other wood burning industries. The present investigation is mainly aimed to use wood waste ash (WA) in cement mortar as partial replacement and addition to cement at different levels. The compressive strength of mortar mixes (1:3 and 1:6) was determined at different curing periods. It is concluded that the increase in the addition of WA decreased the mechanical properties. Whereas the mechanical properties of wood waste ash mortars have increased with 10% of replacement of cement by wood ash. Further increase in replacement level decreased the mechanical properties significantly. It is observed that for both the mortar mix proportions, the compressive strength values have increased with the addition or replacement of WA from 0% to 10%. Beyond 10%, the compressive strength values have decreased. Also, the present research carries out X-ray diffraction analysis (XRD) and scanning electron microscopic analysis (SEM) to examine the microstructural properties of mortar mixes.
