Abstract

Based on the fact that aggregate surface features have a great effect on the performance of concrete, a method for improving concrete performance by modifying aggregate surface features was proposed. Specifically, with aggregates immersed into concrete interfacial agent (CIA) suspension to increase the bond strength of interfaces between the aggregates and mortar, mechanical properties of concrete were improved. Two group experiments were carried out and the results show that concrete with coarse aggregates saturated in CIA has higher cubic compressive strength and lower discreteness of the strength than that of conventional concrete, and cement paste grade 52.5 has a better modification result than RH-1 paste.
