摘要
本文针对混凝土的抗碳化、抗硫酸盐侵蚀、抗氯离子渗透等进行试验研究,对比了不同粉煤灰掺量混凝土的耐久性差异。试验结果表明在低水胶比下,即使在60%的粉煤灰大掺量时,混凝土仍能保证较髙的抗碳化、抗硫酸盐侵蚀、抗氯离子渗透能力。
This paper tested the anti-carbonation properties,sulfate-attack resistance,and anti-chloride ion permeability of concrete,and compared the effect of different fly-ash proportions on the durability.The result showed that at low W/C,the concrete had good anti-carbonation properties,sulfate-attack resistance,and anti-chloride ion permeability even mixed 60% fly-ash.
