RESEARCH ON THE CHARACTERISTIC OF CONCRETE WITH RECYCLED AGGREGATES IN NUCLEAR POWER PLANTS (PART2): EFFECT OF THE CHARACTERISTIC OF HIGH- QUALITY RECYCLED AGGREGATE ON DRYING SHRINKAGE, CARBONATION AND FREEZE - THAW RESISTANCE

Abstract

In our previous report (PartⅠ), the correlation between the characteristics of recycled aggregate and the unit water content, compressive strength and Young's modulus of recycled aggregate concrete was investigated. And this paper described how the characteristics of recycled aggregate were correlated with durability such as drying shrinkage, carbonation and freeze-thaw resistance. Through a series of our reports, the effects of mortar particles on the behavior of recycled aggregate concrete were able to be systematized. This has led to the conception of a method for producing modified recycled aggregate free of mortar particles.
