普通水泥浆体的抗折强度一般较低,通常不超过50～100kg/cm~2,因此其应用范围受到限制,尤其在受弯、受拉的情况下,一般总要配钢筋。虽然已经提出一些办法来提高水泥系材料的抗折强度,如用钢纤维,石棉纤维、有机纤维等来增强,或者在水泥与水拌和时加入水分散性高分 The flexural strength of ordinary cement slurry is generally low, usually not more than 50 ~ 100kg/cm~2, so its application range is limited, especially in the case of bending, tension, the general always equipped with steel. Although some methods have been proposed to improve the flexural strength of cement-based materials, such as reinforcement with steel fibers, asbestos fibers, organic fibers, etc., or adding water-dispersible high points when mixing cement with water.
