Problems solved by technology

However, the strength of the crystals formed inside the concrete cannot be guaranteed, and the pores cannot be completely blocked, so the compressive strength and waterproof effect are poor, and the application site is the concrete base surface, the penetration distance is limited, and the thickness of the waterproof layer is also thin. The effect is limited to the surface of the concrete substrate, which can lead to water seepage if the substrate is cracked, worn or weathered

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a crack-resistant inorganic waterproof material and a preparation method thereof. Background technique [0002] With the increasing urban construction in our country, the construction projects of subways, underground shopping malls, civil air defense facilities, underground parking lots, and underground corridors are coming one after another. In these construction projects, the leakage problem has always been a difficult and miscellaneous disease that plagues the engineering field. Scientific researchers focus on researching and solving important issues. The harm of leakage can accelerate the development of concrete aging diseases, and cause damage to buildings or even accidents, and the loss will be immeasurable. The use of waterproof materials is currently the main way to solve the problem of penetration in construction projects. As the problem of waterproofing in e...
