Influence of Mineral Admixtures on the Carbonation Resistance and Chloride Permeability of Steam-Cured HPC
This paper studies the influence of different mineral admixtures（fly ash and ground granulated blast furnace slag）on the carbonation resistance and chloride permeability of steam-cured HPC. The test results show that under the condition of steam-cured and standard-cured, incorporating 20-30% of the ground granulated blast furnace slag or 15-20% of fly ash decreased the alkalinity and the carbonation resistance of the concrete; with the increase of the proportion of the mineral admixture in concrete, carbonation resistance of HPC was decreased; incorporating 20-30% of the ground granulated blast furnace slag or 15-20% of fly ash improved the chloride permeability of steam-cured concrete, and the influence of ground granulated blast furnace slag is better than that of the fly ash.
