Seawater-corrosion-resistant grouting material dry material and use method thereof
The invention discloses a seawater-corrosion-resistant grouting material dry material and a using method thereof, and relates to the field of buildings. The seawater-corrosion-resistant grouting material dry material is characterized by comprising the following components in parts by weight: 500-600 parts of Portland cement; 20-45 parts of mineral powder; 20-50 parts of silica fume; 50-80 parts ofa CSA expanding agent; 250-350 parts of quartz sand; 4-6 parts of a polycarboxylate superplasticizer; 0.05-0.10 parts of lithium carbonate; 0.5-1.0 parts of calcium formate; 80-100 parts of modifiedhigh-molecular water-absorbent resin, wherein the modified high-molecular water-absorbent resin comprises a high-molecular water-absorbent resin core and a polyvinyl alcohol layer wrapping the surfaceof the modified high-molecular water-absorbent resin core, the polyvinyl alcohol layer is a polyvinyl alcohol film forming matter, the alcoholysis degree of polyvinyl alcohol is 75%-80%, and the seawater-corrosion-resistant grouting material dry material has the advantages of being high in seawater corrosion resistance and stable in mechanical property.
本发明公开了一种抗海水腐蚀的灌浆料干料及其使用方法，涉及建筑领域。其技术要点是：一种抗海水腐蚀的灌浆料干料，包括如下重量份数的组分：硅酸盐水泥 500～600份；矿粉 20～45份；硅灰 20～50份；CSA膨胀剂 50～80份；石英砂 250～350份；聚羧酸减水剂 4～6份；碳酸锂 0.05～0.10份；甲酸钙 0.5～1.0份；改性高分子吸水树脂 80～100份；其中，改性高分子吸水树脂包括高分子吸水树脂内核以及包裹于改性高分子吸水树脂内核表面的聚乙烯醇层，聚乙烯醇层为聚乙烯醇的成膜物，聚乙烯醇的醇解度为75%～80%，其具有抗海水腐蚀能力强、力学性能稳定的优点。
