Some durability properties of ground blast furnace slag and ground basaltic pumice concretes

Abstract

In this research, the durability properties of the concrete incorporating ground blast furnace slag (GBS) and ground basaltic pumice (GBP) each separately or both together were investigated. The fine aggregate of concrete were replaced by GBS and GBP. The abrasion of concrete, compressive strength and microstructure of concrete, which were immersed in sea, was determined. The mechanical abrasion of concretes, which were immersed in tap water, was also determined. The test results showed that the presence of GBS and GBP had a beneficial effect on the compressive strength and chemical abrasion value. The results indicate that the durability of concrete depending on the types and amount of additives. Furthermore, specimen which was made equal percentage of GBS and GBP was found to have higher seawater attack resistance than that of the control concrete. Results showed that concrete used in marinastrucrute, the use of GBS and GBP as fine aggregate could be enhanced concrete durability.
