Study on the durability of concrete using granulated blast furnace slag as fine aggregate
In order to assessing the durability of concrete using granulated blastfurnace slag(GBS)as fine aggregate and compare it with natural river sand concrete,three different size of specimen were produced by using the same mix proportion with 3 different water cement ratios and 3 replacement ratios,and using it to measure the three aspects on the durability of concrete including freeze-thaw performance,dry-shrinkage performance and anti-chloride-permeability performance.In this paper.The test results show that using GBS as fine aggregate can slightly improve anti-chloride-permeability performance and dry-shrinkage performance of concrete in the condition of low water cement ratio,on the other hand,using GBS or natural river sand as fine aggregate has almost similar durability of concrete.
