混凝土防水剂是一种能减少孔隙和填塞毛细通道,可降低混凝土的吸水性或在静水压下的透水性的外加剂。它在许多场合得到了应用。防水剂可显著地提高混凝土的抗渗性能,使混凝土的防水或憎水作用加强,从而使混凝土的渗水,吸水量减少,提高混凝土的耐久性。应用防水剂可配制各种防水混凝土来满足不同防水工程的要求,以及特种防漏工程的要求,提高工程质量。主要应用在工业与民用建筑的基础和地下室、地下铁道、人防工程、隧道、蓄水建筑、港口工程、刚性防水屋面,以及某些特殊工程,如原子能发电站循环水污水箱等方面。
Concrete waterproofing agent is an additive that reduces pores and fills in capillary passages, reduces the water absorption of concrete or water permeability under hydrostatic pressure. It has been applied in many occasions. The water repellent agent can significantly improve the impermeability of the concrete, strengthen the waterproof or hydrophobic effect of the concrete, thereby reducing the water seepage and water absorption of the concrete and improving the durability of the concrete. Waterproofing agent can be used to prepare a variety of waterproof concrete to meet the requirements of different waterproofing projects, as well as the requirements of special leak-proofing projects to improve project quality. Mainly used in industrial and civil construction foundations and basements, underground railways, civil air defense projects, tunnels, water storage buildings, port engineering, rigid waterproof roofing, and some special projects, such as atomic power station circulating water recovery tank.
