PORE STRUCTURE AND CHLORIDE PERMEABILITY OF CONCRETES CONTAINING FLY ASH, BLAST-FURNACE SLAG AND SILICA FUME. FLY ASH, SILICA FUME, SLAG, AND NATURAL POZZOLANS IN CONCRETE. PROCEEDINGS, FOURTH INTERNATIONAL CONFERENCE, ISTANBUL, TURKEY, MAY 1992. VOLUME I
Data is presented on the effects of mineral admixture such as fly ash blast-furnace slag and silica fume on the pore structure and chloride permeability of concrete stored under various environmental conditions for a long time. The results showed that at the surface of concretes containing mineral admixtures the hydration of portland cement and the pozzolanic reaction of mineral admixture were considerably depressed and coarse pores were developed when the concrete specimens were exposed to a dry environment for a long time. Details of the findings are discussed.
