耐磨砼在高速公路收费广场的应用研究

Application of Abrasion Resistant Concrete to Highway Collecting Fees Square

砼的耐磨性受集料的硬度、水泥(砂)浆质量及砼各组成相间的界面结合情况等因素的影响.通过在普通水泥砼中加入活性混合材改善水泥石结构,在保证界面黏结的前提下加入金刚砂提高水泥砂浆耐磨性,可以配制耐磨砼以适应高速公路收费广场的特殊要求.

The abrasion resistance of a concrete is influenced by mangy factors such as aggregates＇ hardness, quality of cement mortar and interface among all concrete＇ s composition. By adding active mixtures to common cement in order to improve the micro-structure of hardened cement paste, or by mixing emery to it to strengthen wear resistance of cement mortar, the concrete can adapt to the special requirement of highway collecting fees square.
