一种材料,比如混凝土,要克服其自身缺陷,最有效的办法是化劣势为优势。水、气体等容易渗入混凝土。处于地下水位之下的基础和板,由于其多孔渗水的特点,水的渗入会在建筑物内产生许多问题。渗入的水和水中溶解的侵蚀性化学物质都能破坏混凝土。混凝土利用自身的毛细孔径作为渗透结晶型防水材料的输送 A material, such as concrete, to overcome its own shortcomings, the most effective way is to disadvantage the advantages. Water, gas and so easy to penetrate the concrete. Because of its porous nature, infiltration of water into the foundations and slabs below the water table creates many problems in the building. Infiltration of water and water dissolved in aggressive chemicals can damage concrete. Concrete uses its own capillary pore size as a permeable crystalline water-repellent material
