The invention discloses a cement-based capillary crystalline waterproof material. The active chemical substances in the cement-based capillary crystalline waterproof material have relatively strong permeability, can be deeply permeated and diffused into internal pores of cement concrete by taking water as a carrier, and chemically react with calcium ions in the concrete to generate water-insoluble silicon-calcium hydrates (branch and tendril-shaped crystals). The crystals are filled with capillary tube pores, the crystals and the concrete are integrated, capillary channels in the concrete are blocked, and therefore the concrete is compact, water leakage is prevented, and the waterproof and anti-seepage functions are achieved. The waterproof material disclosed by the invention has the characteristics and properties of multiple anti-permeability and self-repairing, and has extremely high compression resistance and bending resistance. A waterproof layer prepared from the waterproof material can form a complete system with the surface of concrete, the interface bonding force is high, separation is avoided, and permanent waterproofness can be achieved.
本发明的水泥基渗透结晶防水材料中的活性化学物质由于具有较强的渗透性，能以水为载体深入渗透扩散到水泥混凝土的内部孔隙中，与混凝土中的钙离子发生化学反应，生成不溶于水的硅钙水化物(枝蔓状结晶体),结晶体充满毛细管孔隙并与混凝土结整体,堵塞混凝土内部的毛细孔道,从而使混凝土致密，防止水渗漏，实现防水抗渗功能。本发明的防水材料具有多次抗渗和自我修复的特点和性能,并且具有极强的抗压抗弯折能力。本发明的防水材料所制备的防水层能够与混凝土表面形成完整的体系，界面结合力强，不会分离，可实现永久防水。
