Abstract
Coal bottom ash (bottom ash) has the characteristics of coarse grains like fine aggregate, black to grey in colour and non-glossy. Bottom ash can be used as an alternative material to replace fine aggregate in lightweight mortar mixtures. One of the current technologies for using coal waste (bottom ash) is lightweight mortar for precast walls with other forming materials consisting of foaming agent, cement, sand and water. In this experimental study with a mortar ratio of 1PC : 1PS, the compressive strength of lightweight mortar for use in precast wall elements with the addition of coal waste (bottom ash) as a substitute for fine aggregate is determined. The results showed that the difference in compressive strength value of lightweight mortar with the addition of bottom ash volume at a composition of 30% foaming agent showed that the more the percentage of bottom ash, the lower the compressive strength of lightweight mortar. And for the composition of 50% foaming agent, it is found that the more the percentage of bottom ash, the lower the compressive strength of lightweight mortar, with the addition of foaming agent with a certain percentage, it can be concluded that the more the percentage of foaming agent, the compressive strength value of lightweight mortar increases. The best (ideal) composition of soil ash addition results is the addition of 25% soil ash by weight of sand, foaming agent is found in the composition of 50% with a ratio of 1:60.
