Study on Drying Shrinkage Properties of Concrete Using Blast Furnace Slag as Fine Aggregate

Abstract:

In this paper, the experiment about drying shrinkage of concrete using blast furnace slag as fine aggregate was introduced. In this experiment, blast furnace slag fine aggregates that were produced by two different steel factory and natural river sands that came from two different producing area were been used, and compressive strength of concrete for testing were four levels from ordinary strength level to high strength level. As results, the drying shrinkage of concrete that used blast furnace slag as fine aggregate is less than concrete that used natural river sand as fine aggregate when the mix proportion condition of concrete was identical. The relationship between drying shrinkage and age of drying of concrete that used blast furnace slag as fine aggregate could be described by same approximated curve equation that was used for the concrete using natural river sand as fine aggregate. As same as concrete using natural river sand, the drying shrinkage of concrete that used blast furnace slag as fine aggregate would decrease with decreasing of water cement ratio.
