Experimental studies on water absorption and sorptivity of cashew nut shell ash in mortar

When excess water in mortar evaporates, it leaves voids inside the mortar element creating capillaries which are directly related to the mortar porosity and permeability. Proper selection of ingredients, adequate mix proportioning and following by good construction practices lead to almost impervious mortar. Due to incomplete compaction; mortar may consists of gel pores and capillary pores, which leads to low strength of mortar. Due to problems associated with the absorption test and permeability test; which are measuring the response of mortar to pressure which is rarely the driving force of fluids entering in to mortar; hence there is a need for another type of test. Such test should measure the rate of absorption of water by capillary suction;” Sorptivity “of unsaturated mortar. In this paper the study of sorptivity and water absorption properties of Cashew nut shell Ash mortar. The mix design was carried out for 1:3 proportion cement mortar on the basis of IS 269: 1970.
