| 摘 要： | 利用快硬硫铝酸盐水泥、氨基苯磺酸系高效减水剂和自配的RF早强掺合料配制出了高流动性、5 h抗折强度大于3.5M Pa、抗压强度大于20M Pa的路面快速修补混凝土。对外加剂与胶凝材料的相容性、混凝土的早期抗压强度、抗折强度、新老混凝土界面粘结性能及抗冻性能进行了试验研究,并在实际破损混凝土路面修补中进行了应用。结果表明,所配制的高流动性超早强修补混凝土便于施工操作、力学性能及耐久性能良好,可以应用于各种混凝土路面的修补并能在5 h内恢复交通。 |

| Abstract: | High fluidity and super high-early strength repairing concrete are prepared with sulphate aluminium cement,aminobenzene sulfonamide-type superplasticizer and RF admixture.The compatibility of cement and addictives,compressive strength,flexural strength,interfacial bond and freeze-thaw durability of the concrete are studied and used in concrete pavement mending.The results reveal that the concrete have high fluidity and good mechanics performance and durability,which can be used in rapid repair of concrete pavement and traffic can return to open in 5 hours. |
| Keywords: | rapid repair superplasticizer compatibility early-strength admixtures |
