description To solve the problem of insufficient strength and durability of porous concrete pavement, seven different admixtures were used in this study so that the above properties could be optimized. The strengthening effect of admixtures on the strength and anti-stripping property of porous concrete was evaluated. The effects of different admixtures on the pore characteristics, strength, and anti-stripping of porous concrete were analyzed with CT tomography technology. The relationship between the pore characteristics of porous concrete and its strength, the anti-stripping property, was explored separately, and the correlation between the strength and anti-stripping property was also investigated. The addition of admixtures affected the pore characteristics of porous concrete, and there was no significant correlation between them. The strength of porous concrete was improved by the addition of admixtures, but the addition of different admixtures had different effects on the improvement of strength. Meanwhile, there was no significant correlation between the strength and pore characteristics. Adding admixtures could improve the anti-stripping property of porous concrete, however, different admixtures had different improvement effects. The effect of porosity on anti-stripping property was limited, while the pore number and equivalent aperture had no effect. There was no obvious correlation between the strength and anti-stripping property of porous concrete prepared with different admixtures.
