| 摘 要： | 该新型防水剂产品能从根本上解决混凝土中毛细孔吸水问题,防止混凝土结构被氯离子渗透,从而防止钢筋锈蚀。对该防水剂的性能进行测试研究,综合测试其对砂浆和混凝土相关性能的影响;率先采用英国标准评价混凝土吸水率;并比对该新型防水剂与某国外同类成熟产品的相关性能。该防水剂对混凝土和砂浆的7 d和28 d抗压强度均有良好的增益效果,在不改变工作性能的情况下,能有效改善混凝土和砂浆的抗渗能力。

| Abstract: | A new kind water-proofing additive can fundamentally prevent water absorption through the capillary pore and keep chlorine ion out of the concrete structure,so as to prevent reinforcement corrosion.This paper studies the performance of the new-kind water-proofing additive,including the influence on both mortar and concrete;Takes the lead to use the British Standard to evaluate the water absorption rate of concrete;Furthermore,it compares it with the same-kind similar foreign products.The new-kind water-proofing additive can improve 7 d and 28 d compressive strength and the anti-permeability of both mortar and concrete in case of no changing the working performance. |

| Keywords: | water-proofing additive capillary pore resistance to chloride ion permeability water absorption rate |
