Ready mixed concrete plants near the cement factory often use cement of high temperature, because fresh cement is directly provided from the cement factory. According to a previous investigation, concrete with high temperature cement indicates significant slump-loss. The purpose of this study is to propose an effective mixture to reduce slump-loss of the concrete. The experimental study firstly investigates flowabilities of paste using alternative materials of cement, i.e. fly-ash and limestone powder. In addition, this paper reports slump tests of concrete using the powder materials. The experimental investigation indicates that concrete with 20% replacement of fly-ash can effectively reduce slump-loss.
