机场道面除冰液对机场高性能混凝土具有一定的腐蚀性，采用浸泡腐蚀法研究了粉煤灰高性能混凝土在25%的醋酸钙镁（机场道面除冰液主要成分）溶液中的抗腐蚀性。结果表明，25%的醋酸钙镁溶液长期作用下对于粉煤灰高性能混凝土内部没有化学腐蚀作用，当粉煤灰掺量越高，高性能混凝土的抗醋酸钙镁剥蚀能力越强。相对抗硫酸盐水泥高性能混凝土而言，硅酸盐水泥高性能混凝土表现出更为出色的抗醋酸钙镁剥蚀能力。因此，采用较大掺量的粉煤灰作为矿物掺合料，以硅酸盐水泥作为胶凝材料，制备的高性能混凝土具有非常好的抗醋酸钙镁表面剥蚀性能。

Airfield pavement deicer has a certain corrosive to high performance concrete.Studied corrosion resistance using immer-sion corrosion of fly ash high performance concrete in a 25% solution of calcium magnesium acetate.The results showed that 25% of the long-term effect calcium magnesium acetate solution for fly ash high performance concrete no internal chemical corrosion.When the fly ash higher dosage,high performance concrete,the stronger anti-erosion calcium magnesium acetate.Relative terms against Sulphate resisting cement high performance concrete,the Portland cement high performance concrete exhibit more excellent anti-erosion ability calcium magnesium acetate.Therefore,the use of fly ash as a larger mineral admixture to Portland cement as gelling materials,preparation of high performance concrete has a very good resistance to surface erosion calcium magnesium acetate performance.
