Concrete self-repairing waterproof agent
The invention discloses a concrete self-repairing waterproof agent, which is prepared from the following ingredients in parts by weight: 10 to 12 parts of potassium silicate, 20 to 22 parts of lithium silicate, 1 to 2 parts of water reducing agents, 25 to 28 parts of micro silicon powder, 6 to 20 parts of filling agents, 5 to 8 parts of calcium hydroxide, 3 to 5 parts of calcium formate and 15 to 18 parts of inorganic silicon powder. The waterproof agent disclosed by the invention is a self-repairing inorganic waterproof material doped in concrete, and can be subjected to compound chain reaction with clinker and hydration products in cement to form crystals to block cracks and capillary channels in the concrete, so that the strength, impermeability and other properties of the concrete can be greatly improved.
本发明公开了一种混凝土自修复防水剂，按重量份计，包括：硅酸钾10‑12份、所述硅酸锂20‑22份、减水剂1‑2份、微硅粉25‑28份、填充剂6‑20份、氢氧化钙5‑8份、甲酸钙3‑5份、无机硅粉15‑18份。本发明的防水剂是一种混凝土内掺自修复型无机防水材料，能够与水泥中熟料以及水化产物发生复式链化反应形成结晶体，堵塞混凝土内的裂缝及毛细孔道，可大大提高混凝土的强度及抗渗等性能。
