海韵牌BT-7009型硫铝酸盐水泥用速凝剂对硫铝酸盐水泥的促凝效果是十分明显的，凝结时间从30min 缩短到3min。除了速凝作用外，速凝剂对硫铝酸盐水泥还有以下作用：

　　Chaton brand BT-7009 type sulfur aluminates alite-suiphoaluminate cement with quick coagulation of sulfur aluminates alite-suiphoaluminate cement of coagulant effect is extremely obvious, setting time from 30min shorten to 3min. In addition to speed, accelerating the coagulation effect of sulfur aluminates alite-suiphoaluminate cement and the following function:

1 、缩短初、终凝时间差的作用。正常的硫铝酸盐水泥初、终凝时间的间隔一般为20～30min 。在加入速凝剂后，不仅初凝时间缩短，而且初、终凝时间间隔缩短到10min之内。

1, shorten the first-landfall and last-landfall coagulation time of function. Normal sulfur aluminates alite-suiphoaluminate cement the first-landfall and last-landfall coagulation time interval is commonly 20～30min. Before joining herein, not only initial set time shortens, and the first-landfall and last-landfall coagulation time interval shorten to 10min within.

2 、增加早期强度的作用。在加入速凝剂后，早期强度大大提高，特别是 6h 强度可以提高 2～4 倍。在加入一定量后，2h 强度也大大提高。

2, increase early strength of function. Before joining herein, early strength greatly improved, especially 6h intensity can raise 2～4 times. Before joining a certain amount, 2h strength also rises greatly.

3 、加入量小。在加入量达到 0.3% 之后，再增加速凝剂的加入量不但不会起促凝作用，反而对硫铝酸盐水泥的后期强度不利，造成后期强度大幅度倒缩。因此对硫铝酸盐水泥来说，基础速凝剂的最大掺量为 0.3% 。

3, add small amount. In addition amount to 0.3%, then increase the addition amount not only accelerating won't rise coagutant role, instead of sulfur aluminates salt cement post strength adverse, causing post strength greatly pour shrinking. Therefore for sulfur aluminates alite-suiphoaluminate cement speaking, the biggest based accelerating the admixture of 0.3%.
