摘　　要：该文以碱矿渣胶凝材料作为胶结材,使用级配合理的普通砂、石集料来制备装配式构件高强混凝土,并采用蒸汽养护制度以加速混凝土的强度发展。文章较全面的研究了裹浆工艺、养护方式、配制参数及碱组分等因素对装配式构件高强混凝土强度的影响,确定了装配式构件高强混凝土的制备技术条件及参数。With alkali-activated slag material as cemented material and, combined with reasonable ordinary sand and aggregate, high-strength concrete of prefabricated members is prefabricated, and its strength development is accelerated with steam curing system. This paper studies impact of factors like wrapped slurry, curing method, fabrication parameters and alkaline constituents on the strength of high-strength concrete of prefabricated members, with preparation technological conditions and parameters determined.
