High-toughness waterproof self-repairing concrete as well as preparation method and application thereof
The invention discloses preparation and construction processes of high-toughness waterproof self-repairing concrete for a sealing layer. The high-toughness waterproof self-repairing concrete is prepared from fly ash, fine sand, an expanding agent, a repairing agent, heavy calcium powder, fibers, cellulose ether, dispersible latex powder, a water reducing agent, a water repellent agent, water and optional cement. The invention further provides a construction process for applying the high-toughness waterproof self-repairing concrete to a ballastless track sealing layer of a high-speed railway. The concrete has the advantages that the raw materials are simple and easy to obtain, the concrete has the advantages of high toughness, high crack resistance, super waterproofness, self-repairing and the like, construction can be performed in a pumping mode, and construction is convenient.
本发明公开了一种封闭层用高韧性防水自修复混凝土的制备及施工工艺，该高韧性防水自修复混凝土包括粉煤灰、细砂、膨胀剂、修复剂、重钙粉、纤维、纤维素醚、可分散乳胶粉、减水剂、疏水剂、水以及任选的水泥。本发明还提出了将上述高韧性防水自修复混凝土应用于高速铁路无砟轨道封闭层的施工工艺。本发明具有原材料简单易得，混凝土具有高韧性、高抗裂性、超防水、自修复等优点，且可采用泵送的方式进行施工，施工方便。
