High polymer duct grouting material and preparation method thereof
The invention discloses a high polymer duct grouting material and a preparation method thereof, and relates to the field of civil engineering construction. Comprising the following components in parts by weight: 70-90 parts of Portland cement, 5-25 parts of an active mineral admixture, 10-30 parts of a composite stirred material, 2-5 parts of an air entraining and water reducing agent, 3-5 parts of a polycarboxylate superplasticizer, 20-35 parts of a fiber expanding agent, 0.2-0.5 part of a defoaming agent, 0.03-0.08 part of an anti-settling agent, 0.2-0.5 part of an anti-freezing agent and 0.5-1.0 part of carbon fibers, the grouting material provided by the invention has proper initial setting time and final setting time, the strength and fluidity of the slurry can be greatly improved, the segregation and bleeding of the slurry are reduced, and the later shrinkage is reduced; and the binding power between the slurry and the reinforcing steel bar and the duct wall can be improved, the corrosion of the reinforcing steel bar is prevented, the compressive strength and the breaking strength are high, the performance is stable, the use is simple and convenient, and the mortar can be widely applied to the construction of roads, bridges and culverts.
一种高聚物孔道压浆料及其制备方法，涉及土木工程建设领域，高聚物孔道压浆料，按质量份数计，包括如下组分：硅酸盐水泥70～90份、活性矿物掺和料5～25份、复合搅拌物10～30份、引气减水剂2～5份、聚羧酸高效减水剂3～5份、纤维膨胀剂20～35份、消泡剂0.2～0.5份、防沉剂0.03～0.08份、防冻剂0.2～0.5份、碳纤维0.5～1.0份；本发明所提供的压浆料具有合适的初凝时间和终凝时间，又可以很大程度的增大浆体的强度、流动性，减小浆体的离析、泌水，减少后期收缩；还能提高浆体与钢筋、孔道壁之间的粘结力，防止了钢筋的锈蚀，同时抗压强度与抗折强度均较高，性能稳定，使用简单方便，可广泛应用在如公路桥涵施工中。
