预应力灰砂混凝土建筑构件研究

Prestress sand-lime Concrete buildmember

本文介绍了采用石灰、粉砂为主要原材料生产灰砂预应力多孔板构件的最新研究成果。论述了高碱性灰砂混凝土的力学性能、设计取值、配筋及结构检验依据,以及开发灰砂预应力构件的意义。

In this paper the results of recent investiga- tion on prestressed lime-sand concrete hollow panel with lime and powdery sand are given.The mechanical properties, parameters for design,arrangement of reinforcement and cons- truction test of high alkaliferous lime-sand concrete ele- ments are presented and the signifitcance for developing prestre- ssed lime-sand concrete elements is discussed.
