Spray reinforced high-ductility concrete and preparation method thereof
The invention relates to spray-reinforced high-ductility concrete and a preparation method thereof. The spraying reinforced high-ductility concrete is prepared from cement, mineral powder, coal ash, quartz sand, polypropylene fibers, a water reducing agent, biogel, a defoaming agent, an expanding agent and water. The toughness and strength of the spray-reinforced high-ductility concrete provided by the invention are greatly higher than those of common concrete, and the spray-reinforced high-ductility concrete has high strength, high toughness, high crack resistance and high damage resistance,and is widely applied to spray reinforcement of building supports, mine tunnels, river channel revetments, concrete structure repair and the like.
本发明是一种喷射加固高延性混凝土及其制备方法；所述喷射加固高延性混凝土包括水泥、矿粉、粉煤灰、石英砂、聚丙烯纤维、减水剂、生物胶、消泡剂、膨胀剂以及水。本发明所提出的喷射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，广泛应用建筑物支护、矿山隧道、河道护坡、混凝土结构修补等的喷射加固。
