摘要
研究了不同养护方式的PHC管桩混凝土耐硫酸盐侵蚀的情况。结果表明,不掺掺合料的混凝土经蒸汽养护后,其耐硫酸盐侵蚀的性能有所降低,而掺有磨细砂的混凝土经压蒸养护工艺后混凝土抗蚀系数较高,抗硫酸盐侵蚀性能良好。
The effects of the sulfate resistance on the prestressed high-intensity concrete piles with different maintenance methods are studied.The results indicate that after steam curing,the sulfate resistance performance of the concrete with no admixtures decreases ,while the corrosion resistance coefficient of concrete with fine sand powder after autoclaved curing process is higher,and its sulfate resistance performance is good.
