    1、水泥胶体量越多自流平水泥收缩也越大。
    1, the amount of cement colloidal self leveling cement shrinkage is also greater.
    2、自流平水泥用水量越大,高强无收缩灌浆料收缩也越大。
    2, self leveling cement water, the greater the strength of shrinkage grouting material shrinkage is greater.
    3、水泥越细、温度越高,收缩越大。
    3, the finer the cement, the higher the temperature, the larger the shrinkage.
    4、当自流平水泥中在掺灰煤灰同时又掺矿粉时,早期收缩随矿粉产量的提高而增大。
    4, when the self leveling cement in lime ash and slag powder, the early shrinkage increases with the increase of powder yield increase.
    5、使用减缩剂,可明显地减小自流平水泥的收缩。
    5, the use of shrinkage reducing agent, can obviously reduce the shrinkage of self leveling cement.
