WebAug 11, 2014 · Test methods – like ASTM 1202, Standard Test Method for Electrical Indication of Concrete’s Ability to Resist Chloride Ion Penetration – monitor the amount of electrical charge passed through cylindrical specimens for six hours. The total charge passed, in coulombs, is related to the specimen’s ability to resist chloride ion penetration. WebFeb 7, 2024 · The permeability of porous concrete increases with increasing RCA content by between 17.12 and 35.66% due to the increased void ratio. The value ranges from 1.84 to 2.86 cm/s, which is high enough to be used as a drainage system. This shows that as the percentage of RCA increases in the mixes, the permeability of the concrete increases.
