聚合物无机胶凝材料减水效果试验研究

Study on the Water-Reducing Effects for Polymeric Inorganic Cementing Material

通过选用不同配比的聚羧酸系、氨基磺酸系和萘系减水剂改进聚合物无机胶凝材料的抗压、耐弯和附着力等物理性能，发现：萘系减水剂的减水效果最差，氨基磺酸系减水剂次之，而聚羧酸系减水剂添加量在0.9%~1.2%时减水效果最好，所得聚合物无机胶凝材料的物理性能也最优。

In this paper, the pressure resistance, bending resistance and adhesive force of polymeric inorganic cementing material were improved by polycarboxylate, aminosulfonic acid series and naphthalene water-reducer by different ratio, which found that naphthalene water-reducer had the worst effect of decreasing water, next is amin-osulfonic acid series water-reducer but polycarboxylate water-reducer had the best effect of decreasing water, and gave the marvelous properties with additional amount about 0 . 9% ~1 . 2%.
