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.
