Experimental investigation on effect of using fine_grained and dolomite powder on physical characteristics of porous concrete separately

The use of porous concrete system in urban areas as a modern and applied management approach during rainfall can prevent the problems by rapid outflow of the surface runoff. In this research, effect of replacing dolomite minerals in two modes of fine-grained and powder, as part of the aggregates or...
