| dc.description.abstract | The cellular lightweight concrete (CLC) or sometimes might often called that foamed concrete is either a cement paste or mortar, classified as lightweight concrete, in which air voids are entrapped in mortar by suitable foaming agent. This research study various mechanical properties of compressive strength, dry density and water absorption of cellular lightweight concrete (CLC), which made from ordinary portland cement, sand , bagasse ash and foaming agent admixture. Bagasse ash use to replace cement in different proportions from 5 to 30 percent by volume of cement. Optimum replacement percentage is determined using cement-sand mortar then applies in CLC. Optimum bagasse ash present is a percentage which gives same or higher performance compare with CLC without bagasse ash. Different mix of CLC with constant water to binder ratio of 0.5, 1.5% foaming admixture and target density of 1600 kg/m3 were tested. 10% replacement of cement with bagasse ash slightly increases compressive strength and dry density, while 15% replacement of cement gives almost same strength with the control mix. The study result shows that replacing cement with bagasse ash up to 15% improves mechanical properties of CLC such as compressive strength, dry density, water absorption and plastic shrinkage.
