引用本文摘 要：試驗研究對比了4種復合液體抗腐蝕劑FS-1~FS-4對水泥膠砂強度和混凝土的工作性、力學性能與耐久性的影響。結果表明：相對于空白樣，4種復合液體抗腐蝕劑均可提高水泥膠砂的抗折強度11.6%~13%，改善混凝土的工作性，提高混凝土28 d抗壓強度14%~15%；通過碳化試驗、抗氯離子滲透試驗以及模擬海水干濕循環試驗得出，4種抗腐蝕劑可以減緩混凝土碳化速率13.0%~21.7%，提高混凝土的抗碳化性能，6 h電通量降低23%~32%，有效降低海洋環境對混凝土強度和質量損失的影響。 Abstract: The effects of four kinds of composite liquid corrosion inhibitors FS-1~FS-4 on the strength of cement mortar and workability, mechanical properties and durability of concrete were studied.The results show that the flexural strength of cement mortar can be improved by 11.6%~13% and the workability of concrete can be improved by 14%~15% compared with the blank sample. Through carbonation test, chloride ion penetration test and simulated seawater dry-wet cycle test, the carbonation rate of concrete can be slowed down by 13.0%~21.7%, and the carbonation resistance of concrete can be improved. The electric flux of concrete can be reduced by 23%~32% after 6 hours. The chloride ion penetration resistance of concrete is improved, and the influence of marine environment on concrete strength and quality loss is effectively reduced.
