为降低修补用碱激发材料的泛碱，通过表面喷涂外加剂、掺加玻璃粉、掺加赤泥的方式研究了修补用碱激发材料的泛碱抑制措施。并通过扫描电镜、氮吸附分析、超景深图像分析等方法分析其抑制机理。结果表明：在砂浆试件表面涂刷PNC401防水涂料或有机硅防水剂后泛碱量分别减少了61.3%和26.7%；玻璃粉、赤泥的掺量在15%内满足修补砂浆各项性能要求；掺加15%的玻璃粉、赤泥后泛碱量分别减少了60.7%、52.0%，且砂浆内部孔隙数量较少，无明显裂缝产生，减少了碱性离子的溶出通道，对修补用碱激发材料的泛碱有很好的抑制效果。

In order to reduce the panalkalisation of alkali-inspired materials for repair, the inhibition of panalkalisation of alkali-inspired materials for repair was investigated by means of surface spraying of admixtures, doping of glass powder, and doping of red mud. The inhibition mechanism was also analysed by scanning electron microscopy, nitrogen adsorption analysis and super depth of field image analysis. The results show as follows. After brushing PNC401 waterproof coating or organosilicon waterproofing agent on the surface of mortar specimen, the amount of alkali flooding is reduced by 61.3% and 26.7%, respectively. The dosage of glass powder and red mud within 15% meets the requirements of the performance of the repair mortar. The amount of alkali flooding was reduced by 60.7% and 52.0% after doping of 15% glass powder and red mud, respectively, and the number of pore spaces inside the mortar was less, no obvious cracks were produced, which reduced the dissolution of alkaline ions. The number of pores inside the mortar is less, and there is no obvious crack, which reduces the dissolution channel of alkaline ions, and it has a good inhibition effect on the alkaline flooding of alkaline stimulating materials for repairing.
