Abstract

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.
