Salt-freezing-resistant high-performance repairing mortar for repairing concrete bridge
The invention discloses salt-freezing-resistant high-performance repairing mortar for repairing a concrete bridge. The repairing mortar comprises deep-layer repairing mortar and thin repairing mortar.The deep repairing mortar comprises the following components in parts by weight, 600 parts of quartz sand, 200 parts of ordinary Portland cement, 100 parts of double-fast anti-cracking sulphoaluminate cement, 40 parts of granulated blast furnace slag powder, 20 parts of silica fume, 8 parts of redispersible latex powder, 4 parts of modified sulfonated melamine, 0.5 parts of a defoaming agent, 0.5parts of a silicon-magnesium lubricant, 0.5 parts of a lithium carbonate coagulant, 0.5 parts of starch ether and 0.5 parts of polyacrylonitrile fiber. The thin-layer repairing mortar comprises the following components in parts by weight: 200 parts of quartz sand, 100 parts of epoxy resin, 100 parts of low-calcium fly ash and 20 parts of a curing agent. According to the salt-freezing-resistant high-performance repairing mortar for repairing a concrete bridge, the deep-layer repairing mortar or the thin-layer repairing mortar can be selected according to actual construction requirements, and different applicability is shown on the basis of salt-freezing denudation resistance, so that the repairing effect of the concrete bridge is improved.
本发明公开了一种混凝土桥梁修复用抗盐冻高性能修补砂浆，包括深层修补砂浆和薄层修补砂浆，所述深层修补砂浆的重量组分如下，石英砂600份、普通硅酸盐水泥200份、双快防裂硫铝水泥100份、粒化高炉矿渣粉40份、硅灰20份、可再分散乳胶粉8份、改性磺化三聚氰胺4份、消泡剂0.5份、硅镁润滑剂0.5份、碳酸锂促凝剂0.5份、淀粉醚0.5份、聚丙烯腈纤维0.5份；所述薄层修补砂浆的重量组分如下，石英砂200份、环氧树脂100份、低钙粉煤灰100份、固化剂20份。该混凝土桥梁修复用抗盐冻高性能修补砂浆，可根据实际施工需要选配深层修补砂浆或薄层修补砂浆，在抗盐冻剥蚀的基础上，分别体现不同的适用性，从而提高了混凝土桥梁的修复效果。
