| 摘 要： | 对同时掺入两种不同聚合物乳液的5组15个混凝土试件进行单轴压力条件下的超声波测试,研究了双掺聚合物水泥混凝土声速和加权谱面积等声学参数与应力的相关关系.研究发现,低应力状态,双掺聚合物水泥混凝士的声-应力敏感性较普通水泥混凝土有所增强,而随着应力水平的增大,其声-应力敏感性都不同程度的减弱.具体表现为:双掺纯丙乳液和聚... |

| Abstract: | Ultrasound test of a total of 5 groups of 15 concrete specimens mixed with 2 different kinds of polymer emulsion are conducted under uniaxial loading condition and researches on the relationship between acoustic parameters and stress such as acoustic velocities and weighted spec-trum area of double-mixed polymer cement concrete are done.Researches find that the sensitivity of ultrasound and stress of double-mixed poly-mer cement concrete has been enhanced compared with Portland cement concrete in low stress... |
| Keywords: | double-mixed polymer emulsion concrete ultrasonic pulse velocity weighted spectrum area stress |
