速凝剂:掺入混凝土中能使混凝土迅速凝结硬化的外加剂。主要种类有无机盐类和有机物类。粉状固体,其掺用量仅占混凝土中水泥用量2%~3%,却能使混凝土在5min内初凝,速凝剂12min内凝结。以达到抢修或井巷中混凝土快速凝结的目的。是喷射混凝土施工法中不可缺少的添加剂。它们的作用是加速水泥的水化硬化,在很短的时间内形成足够的强度,以保证特殊施工的要求。
A low alkaline liquid accelerator for Portland cement(LSA in short)was synthesized by means of organic and inorganic composite.
