摘　　要：活性粉末混凝土(Reactive Powder Concrete,简称RPC)是近年来受到广泛重视的一种新型复合材料,力学性能优越,具有优良的抗压、抗弯、抗裂和耐久性能。随着建筑业以及其他行业的高速发展,玻璃由于其独特的性能而被广泛地使用,使得废弃玻璃大量增加。国内外对废弃玻璃应用于混凝土的制备做了大量研究,分析了利用废弃玻璃粉制备RPC的可行性和环保经济方面的意义以及确定了玻璃粉掺量的最佳配合比。结果表明玻璃粉应用于活性粉末混凝土的制备有技术性能优越、节约成本、便于推广和减少污染的优势,但仍有很多问题未研究。Reactive powder concrete（RPC）has received extensive attention in recent years.It is a new type of composite material which has ex-cellent compression,bending,crack resistance,durability and other properties.With the rapid development of construction and other industries,glass has been widely used because of its unique properties which lead to a significant increase in waste glass.Lots of studies have been done of waste glass to be used in the preparation of concrete at home and abroad.Analyses the feasibility and the significance in environmental protection and economy of making RPC with obsolete glass dust,and determined the best mix proportion of obsolete glass dust.The results show that the glass dust used in the preparation of RPC has many advantages,such as excellent technical performance,cost saving,easy of promotion and reduc-ing pollution.But many problems still have not been studied.
