Characterization of pervious concrete focusing on non-destructive testing
Revista IBRACON de Estruturas e Materiais, 2020 This study aims to investigate the properties of pervious concrete focusing on characterization tests by the Ultrasound Method. For this, three mixtures were produced with the paste/aggregate (P/Ag) ratio ranging from 0.45 to 0.65, water to cement ratio (
