水泥混凝土路面快速修补材料中SO_3的控制

CONTROL OF SO_3 CONTENT IN THE MATERIAL USED FOR RAPID REPAIRING CEMENT BOUND ROADS

在普通硅酸盐水泥中掺入外掺剂，是制备水泥混凝土路面快速修补材料最简便的方法。外掺剂引入水泥中的ＳＯ３对补路材料的许多性能起了决定性的作用。讨论了ＳＯ３的作用机理及限量控制依据。

It is the simplest way in which the material used for rapid repairing cement bound roads can be made that admixtures are added into ordinary portland cement. The SO3 content introduced by the admixtures will make the key influence on many properties of this matinal. The action mechanisms of SO3 and the relevant testimonies to set a limit to SO3 content are discussed in this paper.
