高效减水剂对混凝土性能的影响

Influence on properties of concrete of high range water-reducer

对比研究了三种高效减水剂配制的混凝土的工作性能、力学性能及抗裂性,结果表明,用聚羧酸系减水剂配制的混凝土坍落度损失小、抗裂性能较好而且对混凝土的抗压强度无不良影响,在配制高性能混凝土时,宜选用聚羧酸系减水剂。

This paper through analysis the work, mechanics performance and crack resistance of concrete, which made by three kinds of high range water-reducers. It show that polycarboxylic type water reducer with the preparation of the concrete have small concrete slump loss, better resistance to crack and no harmfulness to compressive-strength. Therefore, in the preparation of high-performance concrete, it is suitable that the department of polycarboxyiate superplasticizer selected.
