Concrete rapid repair construction method suitable for severe cold environment
The invention discloses a concrete rapid repair construction method suitable for a severe cold environment, which comprises the following steps: after a concrete base layer to be repaired is cleaned, brushing an interface agent on the surface of the concrete base layer to be repaired, and then pouring a magnesium phosphate cement repair material to realize repair. According to the interface agent, the temperature of the interface of the magnesium phosphate cement repairing material and the concrete base can be kept at 0 DEG C or above in the early age (2-3 h) through the phase change heat storage function. When the magnesium phosphate cement repairing material is used for treating the surface of the concrete, the 2h bending bonding strength between the magnesium phosphate cement repairing material and the concrete can reach 1.2 MPa or above, so that good bonding performance between the magnesium phosphate cement repairing material and the concrete is ensured, and rapid repairing construction of a damaged concrete pavement or an airfield pavement in a severe cold environment is realized.
本发明公开了一种适用于严寒环境的混凝土快速修复施工方法，在待修补的混凝土基层清理干净之后，在待修补混凝土基层表面涂刷界面剂，然后再浇筑磷酸镁水泥修复材料实现修复，其特征在于，所述界面剂通过相变蓄热功能使磷酸镁水泥修复材料和混凝土基层的界面处温度在早龄期（2~3h）能够保持在0℃以上。采用本发明对混凝土表面进行处理，磷酸镁水泥修复材料与混凝土之间的2h弯曲粘结强度可以达到1.2 MPa以上，从而保证磷酸镁水泥修复材料和混凝土之间均有良好的粘结性能，实现严寒环境下破损混凝土路面或机场道面的快速修复施工。
