高效减水剂对混凝土力学性能影响的研究

Research on the Influence of the High Efficiency Water-reducer Agent on the Concrete Mechanical Properties

通过聚羧酸系高效减水剂和萘系高效减水剂对混凝土力学性能的影响试验分析,结果表明:聚羧酸系高效减水剂的减水效果要优于萘系高效减水剂,其在提高混凝土抗压强度与抗渗性方面的效果较好,而在抗冻性方面与萘系高效减水剂效果相同。

Based on the test of the influence by polycarboxylic acid high efficiency water-reducer agent and the naphthalene one on the concrete mechanical properties,the results are concluded that the polycarboxylic acid water-reducer agent have better water-reducing effect than the naphthalene one.At the same,the compressive strength and impermeability of concrete could be more improved by the polycarboxylate acid water-reducer agent.But there are the same effect of concrete frost resistance between the polycarboxylate acid and the naphthalene.
