Sustainable pervious concrete containing glass powder waste: Performance and modeling

The incorporation of fine powder can improve the performance of pervious concrete, as well as promote environmental benefits when fine powder comes from waste recycling. However, the degree of fine powder incorporation is determined empirically in most cases, which may not lead to maximum efficiency. For this reason, the study proposed an adaptation of the Binder Drainage Test to determine the quantity of fine powder and superplasticizer admixture in pervious concrete. Pervious concrete containing glass powder waste was designed by the adapted Binder Drainage Test and was analyzed through specific mass, compressive strength, and permeability coefficient tests. The results allowed finding optimal mixtures and proposing a model that reproduces the adapted Binder Drainage Test results. Glass powder waste incorporation has generated positive effects on the performance of pervious concrete. The highest compressive strength at 28 days was 23.0 MPa for pervious concrete with 34% of glass powder waste (by cement mass), whereas its permeability coefficient was 10.5 mm s-1. There was a good agreement between experimental and modeled results, and the model makes it possible to indicate the optimal mixture composition for pervious concrete obtained by the adapted Binder Drainage Test. Future studies could use an adapted Binder Drainage Test to determine the quantities of other fine powders in pervious concrete, which allow reaching a better and sustainable production.
