Y. Yanya, Frattura ed Integrità Strutturale, 46 (2018) 343-351; DOI: 10.3221/IGF-ESIS.46.31 350 When the replacement rate of the recycled coarse aggregate was 30%, the compressive strength of the pervious concrete was the largest, 6.71 MPa; when the replacement rate became higher than 30%, the compressive strength stopped increasing. The splitting tensile strength was in a positive correlation with the compressive strength; the splitting tensile strength increased with the increase of the compressive strength. But the compressive strength was in a negative correlation with the porosity; the compressive strength decreased with the increase of the porosity.
