海韵牌BT-7009型硫铝酸盐水泥用速凝剂Chaton brand BT-7009 type sulfur aluminates alite-suiphoaluminate cement with herein执行标准: JC477 — 2005 《喷射混凝土用速凝剂》Execution standard: JC477-2005 "sprayed co
ncrete in accelerating" 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 commo
nly 20~30min. Before joining herein, not o
nly 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**掺量为 0.3% 。3, add small amount. In addition amount to 0.3%, then increase the addition amount not o
nly 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 ba
sed accelerating the admixture of 0.3%.
