摘 要：以40 mm×40 mm×160 mm试件替代10 mm×10 mm×60 mm试件（A法），建立了混凝土抗侵蚀防腐剂抗蚀系数试验方法（B法）。保持养护及腐蚀制度不变，按灰砂比1∶6，流动度（250±5）mm确定了水胶比，使侵蚀溶液浓度提高至15%，分别测试20 ℃侵蚀溶液中和水中90 d砂浆试件的抗压强度，以抗压强度比确定90 d抗蚀系数。结果表明：B法的90 d抗蚀系数与原A法的28 d抗蚀系数结果相吻合，B法是可行的。
Abstract: The corrosion resistance coefficient test method B for environmental corrosion-resistance admixture was established. The traditional 10 mm×10 mm×60 mm specimen (test method A) was replaced by 40 mm×40 mm×160 mm mortar specimen, while the curing and corrosion system remained unchanged, water-cement ratio was determined according to the mortar fluidity of (250±5)mm and the cement-sand ratio was 1∶6. The concentration of corrosion solution was increased to 15%. The compressive strength of mortar in corrosion solution and mortar in water at 20 ℃ for 90 d were tested, respectively. And the corrosion resistance coefficient at 90 d was determined by the compressive strength ratio. The results show that the corrosion resistance coefficient at 90 d of method B is consistent with the corrosion resistance coefficient at 28 d of the original method A. Therefore, test method B is feasible.
