Concrete repairing agent formula and blade coating equipment thereof
The invention relates to a formula of a concrete repairing agent. The formula comprises the following raw materials in parts by weight: a component A: 25 parts of 100-mesh mixed quartz sand, 20 parts of 2mm granular sand, 45 parts of ordinary 425 Portland cement, 1 part of a water reducing agent, 2 parts of anti-crack fibers and 7 parts of 5000-mesh superfine calcium carbonate; the component B is prepared from 60 parts of styrene-butadiene emulsion, 60 parts of styrene-acrylic emulsion, 60 parts of VAE emulsion, 32 parts of water, 5 parts of a sterilizing agent and 3 parts of a defoaming agent; a specific construction process of the formula comprises the following steps: repairing a damaged concrete pavement, cleaning a base surface, spraying the permeable primer once by using resin emulsion, uniformly stirring the component A and the component B according to a ratio of 4: 1 to form paste, flatly smearing by using blade coating equipment, covering a thin film or coarse cotton cloth after hardening, and curing for seven days, wherein the dosage of the component A and the component B is 15-20kg/m < 2 > each time; portland cement which is the same as that of pavement concrete is matched with quartz sand, then water-based resin emulsion is added, the toughness of the concrete is improved, the hardness of the concrete is reduced, water in the concrete is kept to evaporate slowly, and the bulking problem is solved.
本发明涉及一种混凝土修补剂配方，该配方中各原料的重量份数比为：甲组：100目混合石英砂25份、2毫米颗粒砂20份、普通425硅酸盐水泥45份、减水剂1份、抗裂纤维2份和5000目超细碳酸钙7份；乙组：丁苯乳液、苯丙乳液和VAE乳液均60份、水32份、杀菌5份和消泡剂3份；配方的具体施工工艺：损坏的混凝土路面修复，清理干净基面，使用树脂乳液喷涂渗透底漆一遍，甲组：乙组＝4：1搅拌均匀成膏状，通过刮涂设备抹涂平整，每遍用量15‑20kg/平方米，变硬后遮盖薄膜或毛布养护七天；采用与路面混凝土相同的硅酸盐水泥，与石英砂配比后，加入水性树脂乳液，树脂乳液的加入增大混凝土韧性，降低混凝土硬度，保持混凝土水分缓慢蒸发，解决了起鼓难题。
