摘　　要：研究了预湿陶粒对高强轻骨料混凝土强度和收缩性能的影响。结果表明,通过在高强混凝土中掺加部分提前用水浸泡过陶粒的办法,可以减少高强混凝土因水泥用量过大而引起的较大收缩。In this paper,the effect of prewetting haydite on the performance of the compressive strength and shrinkage in high-strength and lightweight aggregate concrete was discussed.It shows that the shrinkage caused by the large content of cement can reduce by partial filling prewetting haydite in the high-strength and lightweight aggregate concrete.

关 键 词：轻集料混凝土 陶粒 收缩
