Hydraulic structure microcrack underwater repairing slurry and preparation method thereof
The invention discloses hydraulic structure microcrack underwater repair slurry and a preparation method thereof, and belongs to the technical field of hydraulic repair materials. The invention relates to a water-based waterproof mortar, which is prepared from the following ingredients in parts by weight: 80 to 100 parts of cement, 70 to 90 parts of blast furnace slag, 15 to 25 parts of nanometer silicon powder, 25 to 35 parts of volume stabilizers, 5 to 8 parts of water reducing agents, 70 to 75 parts of acrylate copolymer emulsion, 10 to 15 parts of water-based epoxy curing agents and 30 to 35 parts of water. The micro-crack underwater repairing slurry has the characteristics of strong dispersion resistance, micro-expansibility in the early stage, slow release of the expansion effect, no shrinkage in the later stage, good fluidity, high filling compactness and the like, effectively utilizes the dispersion resistance and the water penetration resistance of organic components, and has the characteristics of good water permeability resistance, good water permeability resistance and the like. And the cohesiveness of the underwater repairing slurry is improved by compounding the mineral admixture, so that the strength of a consolidated body under an underwater construction maintenance condition is ensured. The underwater repairing slurry is suitable for underwater concrete cracks and underground rock gap cracks with the crack width of 0.1 mm-2. 0mm.
本发明公开了一种水工建筑物微裂缝水下修补浆液及制备方法，属于水工修复材料的技术领域。按照份数比包括以下成分：80~100份的水泥、70~90份的高炉矿渣、15~25份的纳米硅粉、25~35份的体积稳定剂、5~8份的减水剂、70~75份的丙烯酸酯共聚乳液、10~15份的水性环氧固化剂以及水30~35份。本发明所述微裂缝水下修补浆液具有抗分散性强，早期具备微膨胀性，并可实现膨胀效应的缓慢释放，后期不收缩，流动性好，填充密实度高等特点，有效利用了有机组分的抗分散性和抗水渗透性能的同时，通过复配矿物掺合料来提升水下修补浆液的粘聚性，保证了水下施工养护条件下的固结体强度。该种水下修补浆液适用于裂缝宽度为0.1mm~2.0mm的水下混凝土裂缝和地下岩隙裂缝。
