However, the common cement concrete has the defects of low compression and fracture resistance, low environmental corrosion resistance and durability, poor wear resistance and the like. Concrete is the most important building material in hydraulic engineering, especially large hydraulic engineering. The requirements on the material are extremely high, and the material is required to have better impermeability, heat resistance and low shrinkage; when the paint is used at a part flushed by high-speed water flow, the paint is required to have scouring resistance, wear resistance, cavitation resistance and the like; in cold regions, particularly in water level fluctuation regions, high frost resistance and corrosion resistance are required. Vermiculite is rarely used in existing building materials because of its strong water absorption.
