Mechanical strengths and durability properties of pervious concretes with blended steel slag and natural aggregate

Steel slag (SS) was used to replace natural aggregate (NA) in pervious concretes (PCs) and important properties of the PCs were investigated in this work. The replacement levels of SS were 25%, 50%, 75% and 100%, respectively. The properties of the PCs, including the compressive strength, the splitting tensile strength and the flexural strength as well as the bulk density, the connected porosity and the water permeability coefficient, were...
