用于生产自应力管的硅酸盐自应力水泥,应具有合适的膨胀量和一定的膨胀速度,在水养阶段其试件各龄期强度的发展还要基本平衡,以使管体获得较高的自应力值。要满足上述要求,就必须掌握好配制工艺这一生产环节。我厂配料质量多年来基本稳定,自应力值达30～40公斤/厘米~2。下面就配制工艺、测试方法、控制范围及最佳配料方案作些介绍。
The silicate self-stressing cement used in the production of self-stressing pipes should have a suitable amount of expansion and a certain rate of expansion. In the water-holding stage, the development of the strength of each sample in the water-in-water phase must be basically balanced so that the pipe body can obtain better performance. High self-stress value. To meet the above requirements, we must master the production process of this production process. The quality of ingredients in our factory is basically stable for many years, and the self-stress value reaches 30-40 kg/cm~2. The following describes the preparation process, test methods, control range, and the best dosing plan.
