英文摘要	In this study, pervious concrete (PC) was prepared by partially replacing the cement with waste glass powder (WGP). The effects of varying the WGP content (0%, 10%, 15%, 20%, and 25%) and water -cement ratio (w/c) (0.22, 0.24, 0.26, and 0.28) on the mechanical properties, water permeability, and frost resistance of PC were analyzed. The results showed that the compressive strength of the PC initially increased and then decreased with the increasing w/c. With an increase in the WGP content, the com-pressive strength decreased in the early stage (28 d), and slowly increased in the middle stage (56 d); however, at the age of 112 d, this value first increased and then decreased. Similar trends were observed for the splitting tensile and flexural strengths of the PC. The water permeability of the PC first increased and then decreased with increasing w/c. With the increasing WGP content, the water permeability pre-sented a downward trend. In addition, it was observed that the increase in WGP content can improve the freeze-thaw resistance of the PC. Based on the experimental data, a series of models was established to predict the effect of the w/c and WGP content on compressive strength and water permeability of PC using a non-linear surface fitting method. The proposed models showed good agreement with the exper-imental results. (c) 2021 Elsevier Ltd. All rights reserved.
