Problems solved by technology

But all do not provide concrete chemical composition in above-mentioned prior art
In addition, similar products are in the form of powder. When applying, add appropriate amount of water and mix to form a slurry to smear on the surface of the concrete structure. The thickness of the coating is generally controlled at 10~20mm. The waterproof effect is closely related to the quality of the construction, and the construction is more troublesome. Construction quality seriously affects its waterproof effect

Description

Technical field [0001] The invention relates to a material in the technical field of construction engineering and a preparation method thereof, in particular to an aqueous permeable crystalline waterproof material and a preparation method thereof. Background technique [0002] As a widely used building material, concrete plays a huge role in modern construction engineering. However, due to some inherent defects and shortcomings of concrete during use, leakage often occurs. To explore the phenomenon of concrete leakage, the most fundamental reason is that concrete is a heterogeneous material. There are many pores inside. Under certain water pressure, these pores are interconnected and eventually lead to leakage. Therefore, over the years, a lot of research work has been carried out on how to improve the compactness of concrete and block its internal pores, such as adding various waterproofing agents and fine mineral additives. These measures have indeed played a great role in im...
