摘　　要：通过在不同胶凝材料用量、不同粉煤灰掺量和不同水胶比下大掺量粉煤灰混凝土碳化和钢筋锈蚀试验,明确了其抵抗碳化和钢筋锈蚀的基本条件。结果显示水胶比是关键条件,只要保证足够低的水胶比,大掺量粉煤灰混凝土具有优异的耐久性。Carbonation resistance and steel corrosion-resistance of high volume fly ash concrete with different content of ce- menting material, fly ash and water-binder ratio were researched in this paper. This paper showed the basic technical measures. To control water-binder ratio is the key technology. High volume fly ash concrete with low enough water-binder ratio can also have excellent durability.
