Study on Freeze-thaw Resistance of Polymer Mortar with Different Proportion Of Silica Fume
At present,the crack diseases of highway pavement are mostly repaired by surface filling with emulsified asphalt,hot mix asphalt mixture,etc.This article determines the optimal mix ratio of geopolymer grouting materials within the horizontal range through orthogonal test,and compares the freeze-thaw resistance performance of geopolymer grouting materials under different silica fume proportion through freeze-thaw resistance tests.The experimental results show that with the increase of silica fumeproportion,the quality loss rate of geopolymer grouting material increases,but the strength loss first increases and then decreases.To ensure comprehensive road performance,it is recommended that the silica fume content should not exceed 5%.
