摘要
对掺入高活性特细掺和料(FC掺和料)的混凝土进行硫酸盐侵蚀试验 ,试验表明在混凝土中掺加适量FC料 ,可以提高混凝土的耐腐蚀性能。从微观孔结构分析了FC掺和料提高高性能混凝土抗硫酸盐腐蚀性能的机理。指出硫酸根离子 (SO42 -)在混凝土中起到了激发FC掺和料及腐蚀混凝土的双重作用。
The experiments for sulfate corrosion on concrete with high activity and superfine admixture (FC admixture) are carried out. The tests show that the concrete resistance to corrosion can be greatly increased by adding proper FC admixture into concrete. The mechanism of FC admixture increasing the high performance concrete resistance to sulfate corrosion is analyzed as viewed from micro structure.The sulfate radical ion (SO42-) has two actions in concrete: exciting FC admixture and corroding concrete.
