concrete patching meaning in English
混凝土路面修补
Examples
- Through many project applications and long - term performance testing , it is proved that the polymer cement mortar is one kind of ideal concrete patching and shielding material
经过多年工程应用和长期性能测试表明，聚合物水泥砂浆是一种理想的混凝土修补防护材料。 - Specially , the axial tensile strength of the interface of the new and old concrete has reached above 2 . 40mpa , greatly surpassing the preconcert goal ( > 1 . 0mpa ) , and its flexural strength also above 5 . 80mpa , having surpassed the preconcert target and the standard request ( 4 . 50mpa ) . ( 2 ) after hardening 4h and 8h the compressive strength of the patched concrete is bigger than 20 mpa , which can satisfy the request of fast patching . ( 3 ) the ych color material , which is mixed into rapid sulfoaluminate cement - concrete patching material , can take better effect and avoid chromatism on the appearance of new - old concrete
特别是新老混凝土界面的轴向抗拉强度已达2 . 40mpa以上,大大超过原定目标(大于1 . 0mpa ) ,其界面抗折强度也在5 . 80mpa以上,也已超过原定指标及规范要求(大于或等于4 . 50mpa ) ; ( 2 )修补混凝土硬化后4h 、 8h抗压强度大于20mpa ,能满足快速修补的要求; ( 3 )在快硬硫铝酸盐水泥混凝土修补材料中掺入自配的ych调色材料,能较好地起到调色作用,避免新老混凝土表面色差。
