Frost Resistance of Pervious Concrete Mixed with Waste Glass Powder

Abstract

The contents of waste glass powder (WGP) (0%, 10%, 15%, 20%, 25%) and water-binder ratio (W/C) (0.24, 0.26, 0.28) were used as influencing factors, and the quality loss rate (Δm) and compressive strength loss rate (Δfc) were used as characterization parameters. The Ca/Si ratio and main element contents of C-S-H gels with different WGP content were investigated by energy dispersive spectrometry (EDS). The pore structure evolution characteristics of WGP composite cementing materials were investigated by low field nuclear magnetic resonance (NMR). Using Δfc as the index of frost resistance degradation and Weibull function, the frost resistance degradation of glass doped pervious concrete (WGP-PC) was modeled. The results show that, with WGP, for the same number of cycles, Δm and Δfc decrease and increase with the increase of WGP. Under the same WGP content, Δm and Δfc decrease first and then increase with the increase of W/C. After 100 freeze-thaw cycles, the samples with WGP content of 20% and W/C of 0.26 have the best freeze-resistance. Microscopic tests show that with the increase of WGP content, the Ca/Si ratio of C-S-H gel decreases at first and then increases with the increase of WGP content. The extreme value of Ca/Si is 2.36 when WGP is added by 20%. The pore volume of hardened paste with 20% WGP content decreased by 18.6% compared with that of cement system without WGP. The overall compactness of the specimen was improved. On the basis of the test data, a life prediction model was established according to Weibull function. The experiment showed that Δfc could be used as a durability degradation index, and the slope of the reliability curve became gentle after WGP was added, which reduced the damage degradation rate of PC. W/C was 0.26. It’s about 5 000 hours.
