Press-plastering reinforced high-ductility concrete and preparation method thereof
The invention relates to press-plastering reinforced high-ductility concrete and a preparation method thereof. The press-plastering reinforced high-ductility concrete is prepared from cement, mineralpowder, steel slag powder, quartz sand, polypropylene fibers, a water reducing agent, biogel, a defoaming agent, an expanding agent and water. The toughness and strength of the press-plastering reinforced high-ductility concrete provided by the invention are greatly higher than those of common concrete, and the concrete has high strength, high toughness, high crack resistance and high damage resistance, and is widely applied to structural repair, press-plastering reinforcement treatment and the like of projects such as house buildings, bridges and tunnels. Besides, a large amount of industrialsolid waste can be utilized by pressing, plastering and reinforcing the high-ductility concrete, so that the requirement for resource regeneration and recycling is met, the production cost is reduced, the environmental protection advantage is achieved, and high social benefits and economic benefits are achieved.
本发明是一种压抹加固高延性混凝土及其制备方法；所述压抹加固高延性混凝土包括水泥、矿粉、钢渣粉、石英砂、聚丙烯纤维、减水剂、生物胶、消泡剂、膨胀剂以及水，本发明所提出的压抹加固高延性混凝土其韧性和强度大大高于普通混凝土，具有高强度、高韧性、高抗裂性能和高耐损伤能力，广泛应用于房屋建筑、桥梁隧道等工程的结构修补、压抹加固处理等。此外，压抹加固高延性混凝土还可以大量利用工业固体废弃物，符合资源再生循环再利用的要求，即降低生产成本又有环保优势，具有较高的社会效益和经济效益。
