Abstract:Concretes containing either latex, Class F fly ash, ground granulated blast-furnace slag, silica fume, or, in some cases, combinations of these ingredients generally are found to have lower permeabilities than concretes containing only portland cement as the cementitious material. Concretes with low permeability provide high resistance to penetration by chlorides or other aggressive ions, which is essential for insuring their long-lasting performance when exposed to aggressive chemical attack while in service. The tests conducted show that either the rapid chloride- permeability test (AASHTO T 277 or ASTM C 1202) or the ponding test (AASHTO T 259) (used for periods longer than the standard 90 days) can be used to differentiate the permeability of different concretes. General agreement in the findings of the two tests with respect to chloride permeability is expected, provided that the concretes compared have been exposed to similar conditions and periods of exposure, and that possible interferences with the results of the rapid test have been eliminated.
