| Abstract | The effect of rice hull ash in cement and concrete mixes was investigated. The mechanical properties studied include compression strength, splitting tensile strength, creep, shrinkage, expansion and durability. Two series of tests were conducted and these are referred to as Series A and B. In Series A, rice hull ash was used as aggregate with cement. The amount of cement was kept constant while the rice hull ash and water-cement ratio were varied. In Series B, the rice hull ash was used as partial replacement of cement in an ordinary concrete mix. The water-cement ratio in this mix was also varied. The compressive and splitting tensile strengths in both series were obtained for different mix proportions. Creep and shrinkage properties were obtained from specimens over a 60 day period. The durability of the specimens was measured by repeated wetting and drying process. The effect of rice hull ash on these mechanical properties are discussed. An economic study for the production of lightweight cement-rice hull ash hollow blocks was conducted and the results showed that these can be produced at a price lower than the cement-sand blocks of the same volume sold locally. |
