Experimental study on freezing resistance of permeable concrete mixed with vinyl acetate-ethylene copolymer emulsion and basalt fiber

In recent years, permeable concrete has been widely used in the construction of urban pavement. However, it discovered that during practical use, cracking pavement seasonal freezing areas is more severe due to its poor frost resistance, and phenomenon threshing evident. To obtain meets resistance requirements areas, mixed with basalt fiber VAE-707 emulsion was studied this study. The conclusion drawn from experiments showed compared basic group show under premise satisfying water permeability, compounding 2 kg/m3 2% can improve concrete.
