Abstract

This paper describes a study undertaken to determine the effect of ground calcium carbonate(GCC) cement mortar with respect to sulfate attack. It were investigated visual appearance and expansion of cement mortars with GCC immersed in artificial solution of 5% sodium sulfate during 510days. According to increasing replacement of GCC, the expansion ratio was comparatively superior to GCC0 mortar specimen. The test results indicated that cement mortars with GCC was benefit the resistance of sulfate attack due to micro filler effect.
