| 摘 要： | 采用x射线半定量分析方法研究了在快硬混凝土中掺加缓凝剂和促硬荆对硫铝酸盐水泥凝结时间、水化历程、水化产物种类的影响.结果表明:快硬硫铝酸盐水泥的水化产物主要有Aft、Afm、C4H13及Al(OH)3,而C2S的水化非常缓慢;快硬硫铝酸盐水泥快凝早强的主要原因是Aft的生成,而后期强度发展停滞甚至倒缩的原因主要是Aft...

| Abstract: | The effects of retarder and accelerator on the setting time,hydration progress and hydration products of rapid hardening sulphoaluminate cement are studied by semi-quantitative XRD analysis method.The results show that the main hydration products of rapid hardening sulphoaluminate cement are Aft,AFm,C4AH13 and Al(OH)3,the hydration of C2S proceeds rather slowly.The rapid setting and strength development are due to the formation of AFt,whereas the cease of strength increase and even strength regress of sulph... |
