Problems solved by technology
The crack width of ordinary waterproof mortar and polymer waterproof mortar is large after cracking, and the cracks are concentrated. Once the cracks are formed, they will often run through the entire waterproof layer and cannot prevent the penetration of water.
The tensile strength of traditional waterproof mortar is low, and once it cracks, it will lose its mechanical performance

Abstract
The invention discloses a layered waterproof layer based on fiber concrete and a preparation method thereof. The layered waterproof layer based on the fiber concrete is characterized by being formed by alternately compounding fiber concrete layers and a strong-weak connecting layer, wherein the strong-weak connecting layer is a structural layer which enables the upper fiber concrete layer and thelower fiber concrete layer to be locally strongly connected and locally weakly connected, and the fiber concrete is formed by adding ultra-high molecular weight polyethylene fibers in concrete. The layered-structure waterproof material has the relatively good permeability resistance, water resistance and corrosion resistance, required raw materials are wide in source, energy conservation and environmental protection are achieved, the manufacturing cost is relatively low, the preparation method is simple, construction is convenient, and the layered-structure waterproof material is suitable forvarious waterproof engineering.
Description
technical field [0001] The invention relates to the technical field of waterproof materials, in particular to a waterproof material with a layered structure based on ultra-high ductility fiber concrete and a preparation method thereof. Background technique [0002] With the rapid development of my country's civil construction industry and the improvement of people's living standards, the importance of building waterproofing in the entire construction project is becoming more and more prominent. In recent years, due to problems such as unreasonable selection of waterproof materials, flawed waterproof design, chaotic construction management and insufficient use management, there have been a large number of leakage problems in engineering structures, and a lot of manpower and material resources have been spent on repairing waterproofing projects, which seriously affected the quality of building structures. The use of functions and safety reduces the production and quality of li...
