通过缓凝三元复合制成缓凝高效减水剂，延长初凝时间至20 小时以上，并且对混凝土后期强度无副作用。

Mix with setretarder could make compound dispersants setretarder superplasticizer which could extend initial setting time up to 20h and no negative effect on late compressive strength.

保证混凝土在初凝之前，上下层的连续粘接，以保障混凝土的整体强度。

To ensure that in the initial setting of concrete before the row on the lower bond, so as to safeguard the overall strength of concrete.
