The invention discloses a novel cement-based permeable crystallization type self-repairing waterproof material which is prepared from the following components in parts by weight: 55-75 parts of Portland cement, 25-45 parts of quartz sand, 4-8 parts of an active component A, 4-8 parts of an active component B, 2-5 parts of a calcium ion supplement, 0.2-0.3 part of a water reducing agent, 0.2 part of a water retaining agent and 28-32 parts of water. Wherein the active component A is alkali metal salt; the active component B is silicic acid or metasilicic acid metal salt. Through the scheme, the cement-based permeable crystallization type waterproof material has the advantages of high condensation efficiency, low cost and the like, and has very high practical value and popularization value in the technical field of cement-based permeable crystallization type waterproof materials.
本发明公开了一种新型水泥基渗透结晶型自修复防水材料，由以下重量比例组分组成：55～75份的硅酸盐水泥、25～45份的英砂、4～8份的活性组分A、4～8份的活性组分B、2～5份的钙离子补充剂、0.2～0.3份的减水剂、0.2份的保水剂和28～32份的水。其中，活性组分A为碱金属盐类；所述活性组分B为硅酸或偏硅酸金属盐。通过上述方案，本发明具有凝结效率高、成本低廉等优点，在水泥基渗透结晶型防水材料技术领域具有很高的实用价值和推广价值。
