| 摘 要： | 为提高橡胶混凝土的抗压强度,采用水泥浆包裹橡胶的方法配制混凝土,并进行抗压强度测试;利用SEM、EDXA和显微硬度等测试方法,对混凝土界面过渡区结构进行表征。结果表明:采用水泥浆包裹橡胶集料的方法,与基准混凝土相比较,随橡胶集料掺量的增加,混凝土7d和28d的抗压强度虽有所降低,但降低的幅度较小;橡胶集料掺量30 kg/m~3,混凝土7d和28d的抗压强度分别为普通成型混凝土的141%和136%。水泥浆包裹橡胶法配制的混凝土抗压强度高。

| Abstract: | It is investigated that compressive strength of rubberized concrete with cement paste wrapping rubber aggregate is improved by compressive strength test. And interfacial transition zone of concrete is characterized by scanning electron microscope(SEM),Energy Dispersive X-ray Analysis(EDXA) and microhardness.The results showed that compressive strength of rubberized concrete with cement paste wrapping rubber aggregate was better than that of reference concrete with increasing of rubber at 7d and 28d respectively. Furthermore, when rubber was 30 kg/m3 in concrete, compressive strength of rubberized concrete 7d and 28d was as 141% and 136% as of that of concrete with popular casting. Compressive strength of concrete with cement paste wrapping rubber aggregate is high. |
