- Abstract
This study evaluates the effects of fly ash microsphere (FAM) on the flowability and cohesiveness performance of cement paste. FAM is a superfine fly ash captured from the coal-fired power stations. It has a mean particle size of around 2 mm and is of spherical shape. An experimental program comprising a total of 38 cement paste mixes was launched and the flowability and cohesiveness performance of the mixes were measured. Results showed that addition of FAM up to 40% by volume could improve the flowability but decrease the cohesiveness at the same water to cementitious materials (W/CM) ratio. In general, the cohesiveness of cement paste would decrease with increasing flowability.
