【摘要】 混凝土结构的加固、维护和修补在土木行业中越来越受到重视。修补材料与基体混凝土的相容性将影响被修补结构的耐久性。本文采用修补砂浆与基体混凝土相容性优劣来选择乳液改性硫铝酸盐水泥快硬修补砂浆的配比,分别选用羧基丁苯胶乳和醋酸乙烯酯-乙烯共聚乳液对快硬硫铝酸盐水泥进行改性,研制快硬的高性能修补砂浆。更多还原

【Abstract】 Strengthening,maintenance and repair of concrete structure are more and more highly thought of in the trade of civil engineering.Compatibility of repair materials with matrix concrete was one of the key factors to influence durability of the repaired structure.Good or bad compatibility was taken into account to determine the rapid hardening repair mortar formula.SBR and VAE were selected to modify repaid hardening Sulphoaluminate cement with which high performance repair mortar was developed.更多还原
