Self-repairing hydrophobic concrete and preparation method thereof
The self-repairing hydrophobic concrete is prepared from the following raw materials in parts by weight: 100 parts of cement, 200 to 300 parts of sand, 0.3 to 0.5 part of microspheres, 4.2 to 6 parts of a hydrophobic additive and 0.3 to 0.4 part of a water reducing agent, wherein the zeolite grafted with carbonic anhydrase is coated with sodium alginate to prepare the microspheres. The invention also discloses a preparation method of the self-repairing hydrophobic concrete. Through mutual cooperation of the microspheres and the hydrophobic additive, the hydrophobic self-repairing microsphere has good overall hydrophobic performance and self-repairing performance.
本发明公开了一种自修复疏水混凝土，其原料按重量份包括：水泥100份、砂200‑300份、微球0.3‑0.5份、疏水添加剂4.2‑6份、减水剂0.3‑0.4份；其中，接枝碳酸酐酶的沸石被海藻酸钠包覆制得微球。本发明还公开了上述自修复疏水混凝土的制备方法。本发明通过微球和疏水添加剂相互配合具有良好的整体疏水性能和自修复性能。
