Cement-based capillary crystalline waterproof material
The invention discloses a cement-based capillary crystalline waterproof material which comprises cement as a main material and silicon dioxide, rho aluminum oxide, magnesium oxide, calcium sulfonate, cellulose ether, high-molecular water-absorbent resin, filler, a crystal precipitator, a crystal growth agent, a surfactant, an accelerator and a retarder as auxiliary materials. According to the cement-based capillary crystalline waterproof material and the preparation method thereof, the anti-permeability performance of the cement-based capillary crystalline waterproof material on a concrete test block is improved by changing the proportion of the filler to the high-molecular water-absorbent resin or changing the parts of the raw materials, and the waterproof material prepared according to the first comparison embodiment of multiple embodiments is optimal and has the advantages of being good in waterproof performance and good in waterproof performance. The cement-based capillary crystalline waterproof material effectively avoids the defects of high shrinkage degree, easiness in cracking, poor durability and the like during use, and the preparation steps are simple, convenient and complex, so that the practicability of the cement-based capillary crystalline waterproof material can be improved, and the volume stability of standard concrete is ensured.
本发明公开了一种水泥基渗透结晶的防水材料，包括用水泥作主料，用二氧化硅、ρ氧化铝、氧化镁、磺酸钙、纤维素醚、高分子吸水树脂、填料、结晶沉淀剂、晶体生长剂、表面活性剂、速凝剂和缓凝剂作辅料。本发明通过改变填料和高分子吸水树脂的比例，或者改变原料的份数，从而提升水泥基渗透结晶的防水材料对混凝土试块的抗渗性能，根据多个实施例的对比实施例一制备出的防水材料最优，有效的避免使用时仍然存在收缩程度大、容易开裂、耐久性不良等弊端，且制备的步骤简单方便复杂，进而可提高该水泥基渗透结晶的防水材料的实用性，从而保证基准混凝土体积的稳定性。
