Cement-based repairing mortar for repairing road pavement and preparation method of cement-based repairing mortar
The invention discloses cement-based repair mortar for road pavement repair and a preparation method of the cement-based repair mortar. The cement-based repair mortar is prepared from 380kg of sulfur-aluminum special cement, 540kg of quartz sand, 49.3 kg of heavy calcium carbonate, 25kg of latex powder, 1.2 kg of tartaric acid, 0.6 kg of cellulose, 0.6 kg of a stabilizer, 0.3 kg of lithium sulfate, 2kg of a water reducing agent and 1kg of a defoaming agent. The preparation method comprises the following specific steps: weighing the sulfur-aluminum special cement, the quartz sand and the heavy calcium carbonate by using equipment according to a production formula, adding into a stirring tank, and starting stirring at the same time; manually weighing latex powder, tartaric acid, cellulose, a stabilizer, lithium sulfate, a water reducing agent and a defoaming agent, adding into a stirring tank, and stirring for 5 minutes after all the raw materials are added; sampling and testing, wherein the water-cement ratio is 0.25: 1; and packaging after the test is qualified, and stacking by a manipulator. The cement-based repairing mortar disclosed by the invention has high fluidity; the quick-drying early strength performance is good, and the corrosion resistance is high; and after being dried and solidified, the coating is basically not shrunk and does not crack, and cracks are effectively prevented from appearing on the pavement.
本发明公开了一种用于道路路面修补的水泥基修补砂浆及其制备方法，包括硫铝特种水泥380kg、石英砂540kg、重钙49.3kg、乳胶粉25kg、酒石酸1.2kg、纤维素0.6kg、稳定剂0.6kg、硫酸锂0.3kg、减水剂2kg和消泡剂1kg。具体步骤如下：按生产配方用设备称量硫铝特种水泥、石英砂、重钙，添加至搅拌罐中，同时开启搅拌；人工称量乳胶粉、酒石酸、纤维素、稳定剂、硫酸锂、减水剂和消泡剂，添加至搅拌罐中，添加完所有原料后，搅拌5分钟；取样测试，水灰比0.25:1；测试合格后进行包装，机械手码垛。本发明的水泥基修补砂浆具有高流动度；快干早强性能好、抗腐蚀性能强；无收缩：干固后基本无收缩，既不开裂，有效防止路面出现裂纹。
