抗腐蚀性能好，尤其是抗海水腐蚀优于高抗硫波特兰水泥，抗腐蚀系数大于1。

Good corrosion resistance, especially for seawater corrosion is better than highly resistant Portland cement and the corrosion resistance coefficient is larger than1.

铸铁与水泥热膨胀系数不同，长时间就会变形、分离，在外力作用下翻开。

Cast iron is different from cement thermal expansion coefficient, will transform, separate with long hours, over - towing force action descend turn over the turn on.
