Physical and Hydraulic Properties of Porous Concrete [PDF]

open access: yesSustainability, 2021
The work presented includes a review of the state of art of porous concrete. Its purpose is to evaluate the potential use of porous concrete in constructions where the level of surface runoff justifies it. A review of the literature presented here has been necessary where parameters of special consideration have been defined in the dosage of permeable ...
