INFLUENCE OF FINENESS LEVELS ON THE SULFATE RESISTANCE OF CEMENT MATRIX WITH GGBS

摘要

This paper describes the sulfate resistance of cement matrix with or without ground granulated blast furnace slag (GGBS). Sulfate attack was performed on the cement matrix, which had been prepared by using water-binder ratio of 0.45. Variables were the fineness levels of GGBS and two sulfate solution. Microstructural analyses such as X-ray diffraction (XRD) and scanning electron microscopy (SEM) as well as determination of physical properties, compressive strength and length change were carried out to evaluate the sulfate resistance of GGBS with various fineness levels
