有中抗硫酸盐型(MSR)和高硫酸盐型(hsr)两类，适合于中温、中压的井下条件时使用。
Available in moderate sulfate-resistant (MSR) and high sulfate-resistant (HSR) Grades. This product is intended for use under conditions of moderate high temperatures and pressures.
在混凝土中掺入粉煤灰、矿渣和硅灰等掺合料被认为能有效提高混凝土抗硫酸盐耐久性。
Concrete mingled with fly ash, slag and silica fume and other admixtures are thought to effectively improve the anti-sulfate durability of concrete.
强度越高，混凝土的抗冰冻性能越好，但一些强度较高的混凝土试件在硫酸盐溶液中冻融时发生突然的中部断裂而破坏。
The higher strength is, the better anti-freezing performance, but some concrete samples of high strength occurs sudden breaking in sulfate solution for freeze-thawing.
