浅谈减水剂在泵送混凝土中的应用

Application of water reducing agent in pumping concrete

结合聚羧酸减水剂作用特点和粉煤灰混凝土特点,以连云港伊山华庭工程为例,介绍了聚羧酸高效减水剂在泵送混凝土中的应用,指出使用减水剂后混凝土早期强度高,坍落度损失小,对水泥适应性良好。

Combining with the action features of polyocarboxy acid water-reducer（NOF-AS） and the features of fly-ash concrete, taking Lianyungang Yishanhuating project as the ease, it introduces the application of polyocarboxy acid water-reducer（NOF-AS） in pumping concrete, and points out that early concrete strength increases, collapse damage reduces, and has a good adaptability for cement after using water reducing agent.
