High-strength high-toughness composite compact cementing material
The invention relates to a high-strength high-toughness composite compact cementing material. The material comprises the following components: quartz sand, Portland cement, alkaline mineral powder, silica powder, fly ash, polycarboxylate superplasticizer, an expanding agent, a retarder, a defoaming agent, polyacrylonitrile fibers, moisture-curing single-component polyurethane, polyacrylamide and water. The above technical scheme has excellent physical and chemical properties such as deformability, fatigue strength, wear resistance, bonding strength, freezing resistance, corrosion resistance and permeability resistance, and can be widely applied to the fields of special engineering, saline and alkaline regions, special bridges, roads, bridges and buildings in alpine regions, building maintenance and reinforcement and the like.
本发明涉及一种高强高韧性的复合型密实胶结材料，包括如下组分：石英砂、硅酸盐水泥、碱性矿粉、硅微粉、粉煤灰、聚羧酸高效、膨胀剂、缓凝剂、消泡剂、聚丙烯腈纤维、湿固化型单组份聚氨酯、聚丙烯酰胺和水。本技术方案具有优异的形变能力、疲劳强度、耐磨性、粘接强度、抗冻性和防腐抗渗透性等物理化学性质，可广泛应用于特种工程、盐碱地域、特种桥梁、高寒地区路桥与建筑、建筑维修与加固等领域。
