Face-up rapid repairing agent for bridge and tunnel uninterrupted traffic
The invention relates to the technical field of building materials, and discloses a quick face-up repairing agent for uninterrupted traffic of bridges and tunnels, which is prepared from the following raw materials in parts by weight: compound cement, quartz sand, mineral micro powder, latex powder, a water-retaining agent, a thixotropic lubricant, PVA fibers, sodium aluminate, sodium carbonate and quick lime, the compound cement is formed by compounding ordinary Portland cement and quick-hardening sulphoaluminate cement, and the mineral micro powder is selected from at least one of granulated blast furnace slag, silica fume and first-grade fly ash. According to the rapid face-up repairing agent for bridge and tunnel traffic uninterrupted, through addition of the sodium aluminate, the sodium carbonate, the quick lime, the mineral micro powder and other substances, the repairing agent can conduct face-up repairing construction on bridge and tunnel projects without traffic interruption, early strength and rapid hardening are achieved, and the water retention rate of the repairing agent is greatly increased through the water-retaining agent; by adding substances such as the mineral micro powder and the PVA fibers, the bonding force and the compressive strength of the repairing agent and a base layer are improved.
本发明涉及建筑材料技术领域，且公开了一种用于桥隧不中断交通的仰面快速修补剂，包括以下重量份数配比的原料：复配水泥、石英砂、矿物微粉、乳胶粉、保水剂、触变润滑剂、PVA纤维、铝酸钠、碳酸钠和生石灰，所述复配水泥为普通硅酸盐水泥与快硬硫铝酸盐水泥复配，所述矿物微粉选至粒化高炉矿渣份、硅灰和一级粉煤灰中至少其中一种。该用于桥隧不中断交通的仰面快速修补剂，通过铝酸钠、碳酸钠、生石灰和矿物微粉等物质的添加，使得此修补剂可以不中断交通对桥隧工程进行仰面修补施工，早强快硬，通过保水剂大大提高了修补剂的保水率，通过矿物微粉和PVA纤维等物质的添加提高了修补剂与基层的粘结力和抗压强度。
