摘要
铁路无碴桥桥枕一直是水泥混凝土使用的禁区。鉴于木材供应日趋紧张,需要一种新型替代材料。高强聚合物胶结混凝土就是一种新型替代材料。文中重点介绍了这种材料的原料、配方工艺和主要性能。
As Portland cement concrete has hardly been used for railway bridge sleeper,without
ballast and wood sleeper is in short supply,it is imperative to develop a new material asa nal tern-
ative.Accordingly the high strength polymer concrete was developed.In this paper raw materi-
als,form dation,mannfaecuring process and principal properties of this material were presented.
