海韻牌BT-7009型硫鋁酸鹽水泥用速凝劑Chaton brand BT-7009 type sulfur aluminates alite-suiphoaluminate cement with herein執行標準： JC477 — 2005 《噴射混凝土用速凝劑》Execution standard: JC477-2005 "sprayed concrete in accelerating"　　海韻牌BT-7009型硫鋁酸鹽水泥用速凝劑對硫鋁酸鹽水泥的促凝效果是十分明顯的，凝結時間從30min 縮短到3min。除了速凝作用外，速凝劑對硫鋁酸鹽水泥還有以下作用：　　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 、縮短初、終凝時間差的作用。正常的硫鋁酸鹽水泥初、終凝時間的間隔一般為20～30min 。在加入速凝劑后，不僅初凝時間縮短，而且初、終凝時間間隔縮短到10min之內。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 、增加早期強度的作用。在加入速凝劑后，早期強度大大提高，特別是 6h 強度可以提高 2～4 倍。在加入一定量后，2h 強度也大大提高。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。在加入量達到 0.3% 之后，再增加速凝劑的加入量不但不會起促凝作用，反而對硫鋁酸鹽水泥的后期強度不利，造成后期強度大幅度倒縮。因此對硫鋁酸鹽水泥來說，基礎速凝劑的**摻量為 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%.
