The problem was the worst for the wall made of lightweight blocks. In this research, masonry and<br>plastering mortars made from Portland cement, fly ash, expanded perlite, mortar plasticizer, and sand were<br>tested. The testing program included the determination of water demand, setting time, water retention,<br>compressive strength, splitting tensile strength, density, and elastic modulus. For the masonry mortar, the mixes<br>with high calcium fly ash with or without plasticizer could be used with required properties and reduced cost.<br>The mix of expanded perlite gave water retention over the required 70%. The mix containing fly ash and 0.2%<br>plasticizer gave water retention slightly less than 70%. It was recommended that the mix with expanded perlite<br>should be used for indoor plastering and the mix with fly ash and plasticizer should be used for outdoor<br>plastering.<br><br></p> ER -
