Abstract
This present paper investigates the influence of equivalent control, (moisture content, cement content, the amount of bottom ash from Khon Kaen municipal solid waste ash content, and curing time) on strength development in clay admixed with cement and bottom ash. This paper reveals a possibility of replacing cement with bottom ash to improve strength of clay. It is found that strength increases with bottom ash content. The role of bottom ash is to disperse the clay-cement clusters into smaller clusters, which increases the reactive surface, and hence strength. An addition of 20% bottom ash in the cement gives the highest strength for all combination of water content and cement content. Based on the claywater/cement ratio and the parameter equivalent cement content, the strength prediction equation for the clay admixed cement is introduced. It is found that for all curing times test, bottom ash content is equal to 0.80 cement content for all combinations of water content, cement content and bottom ash content.
