摘　　要：普通页岩陶粒吸水率偏大,对其进行表面憎水处理,可有效降低其吸水率,满足高性能轻集料混凝土(HPLC)配制的需要。本文利用经过表面憎水处理的普通页岩陶粒作为粗集料,配制出28天抗压强度高于30MPa且抗渗等级大于P12的高性能轻集料混凝土,并对其拌合物性能、强度和抗渗性等进行了分析研究。Water-absorption of ordinary expanded shale was too high, it can be red uced greatly and be satisfied to high performance light-weight concrete(HPLC) af ter surface hydrophobic treatment. This paper shows that HPLC which 28days str ength over 30MPa and anti-permeability grade greater than P12 can be produced by that treatment shale haydite. And also studied the workability of the fresh con crete, strength and anti-permeability of the harden concrete.
