试验以粉煤灰、矿粉两种矿物掺合料与液体或固体防腐剂进行组合配置高性能混凝土,通过对其28天和56天抗压强度和电通量的测试,分析混凝土的强度和氯离子渗透性。结果表明,粉煤灰、矿粉与固体防腐剂复合混凝土具有较高的强度和氯离子渗透性,是抗氯盐高性能混凝土。可为桥梁和高速铁路等具有高抗腐蚀性要求的百年混凝土结构设计提供参考。
試驗以粉煤灰、礦粉兩種礦物摻閤料與液體或固體防腐劑進行組閤配置高性能混凝土,通過對其28天和56天抗壓彊度和電通量的測試,分析混凝土的彊度和氯離子滲透性。結果錶明,粉煤灰、礦粉與固體防腐劑複閤混凝土具有較高的彊度和氯離子滲透性,是抗氯鹽高性能混凝土。可為橋樑和高速鐵路等具有高抗腐蝕性要求的百年混凝土結構設計提供參攷。

Flyash and mineral powder mixture with liquid or solid preservative are used to prepare high-performance concrete in the test.Through test on compressive strength and dielectric flux for 28 days and 56 days,concrete strength and chloride ion penetration are analyzed.The result shows that flyash,mineral powder and solid preservative reinforced composite concrete has higher compressive strength and chloride ion penetration,with high resistance to chloride salt,which can provide reference for century concrete structure design of bridge and high-speed railway with the requirement of high corrosion resistance.
