1)  retarding mortar
缓凝砂浆
1.
The key problem of retard-bonded prestressed concrete is that the retarding materials around the prestressed tendons would not harden until the prestressed tendons are tensioned,so experimental study on retarding mortar is carried out.
通过大量的正交试验和理论分析,研制了一种能满足缓粘结预应力体系的缓凝砂浆,其初凝时间可以根据复合缓凝剂的掺量和养护温度从几小时到十几天任意调节,缓凝砂浆28d抗压强度达到35MPa以上。

补充资料:缓凝剂
分子式:
CAS号:

性质:掺入混凝土中能延长混凝土凝结时间的外加剂。其掺用量仅为混凝土中水泥用量的千分之几即可延缓凝结时间由几小时到几天不等。其主要成分为糖类、酒石酸钾钠、柠檬酸等物质。可单独使用,亦可与减水剂、外气剂等复合使用。
