摘　　要：本文研究了煤矸石掺量达60％、强度标号达425#的大掺量煤矸石水泥的抗硫酸盐侵蚀性能。研究表明，这种水泥具有较强的抗硫酸盐侵蚀性能，其原因在于水泥石的致密度较高且水泥中的C3A含量较少。The sulfate - resistant property of the large gangue content cement with the coal gangue addition up to 60% and the strength grade of 425 # is studied in this paper. The study reveals that this kind of cement has an excellent sulfateresistant property as the hardened cement paste has rather high demeness and there is a rather low content of C3A in cement.
