摘要
采用8字形新老砂浆抗拉粘结强度的试验方法,研究了不同粘结砂浆粘结材料在不同配比条件下的粘结性能,得到了不同粘结材料抗拉强度的变化规律。试验结果表明,碳纳米管增强水泥砂浆粘结性能良好,适宜作为新老混凝土界面修补材料。
The figure 8 new and old mortar tensile test method is used for bond strength of adhesive mortar, bonding material in different mixture ratio under conditions of adhesive properties of different bonding materi-als, and the variation law of tensile strength is obtained as well. The test results show that carbon nanotubes reinforced cement mortar performance is good, which is suitable as an interface between new and old concrete repair materials.
