摘要
对掺加相变物质的水泥水化放热速率及放热总量分析的结果表明,相变物质显著影响水泥水化过程并有效改变水泥放热总量。直接加入相变物质对水泥净浆流动度和混凝土的抗压强度也会产生一定的负面影响。
By analyzing the rate of exothermic hydration and total hydration heat of cement with and without PCM,It was found that PCM had a remarkable influence on the cement hydration process as well as the total hydration heat evolution.PCM also had an negative effect on the flow of cement paste and compressive strength of concrete.
