Five ASTM Type V portland cements, two portland blast-furnace slag cements, and two portland pozzolan cements are evaluated for sulfate resistance by a new laboratory method which is reliable, quick and reproducible. It is concluded that significant differences existed in the sulfate resisting character of commercial Type V cements. Similarly large variations were found in the sulfate resisting behavior of portland slag cements and portland pozzolan cements. An attempt is made to explain these variations with the help of X-ray diffraction analyses of the specimens.
