2018-1-15  The aggregate gradation of porous concrete is a key issue affecting its strength and permeability. Aggregate sized 9.5–12.5 mm results in higher strength of porous concrete than aggregate sized 2.36–9.5 mm at the same porosity because of a higher amount of paste between conjoint points , while fine aggregate can improve the distribution of cement paste and thus enhance the compressive ...
