摘要
制备出高阻尼混凝土并采用快速氯离子渗透法研究了轻集料掺量及其掺入方式对其抗渗性能的影响。结果表明,与同强度等级的普通混凝土相比,高阻尼混凝土具有更好的阻尼功能和抗渗性能,提高轻集料掺量或延长轻集料预湿时间,可较明显地改善高阻尼混凝土的阻尼功能和抗渗性能;利用SEM、孔结构试验探讨了轻集料提高阻尼混凝土抗渗性的作用机理。
The high damping concrete was prepared,and the effect of lightweight aggregate on the impermeability of high damping concrete conducted with a rapid chloride permeability method was investigated.High damping concrete exhibited better impermeability than normal concrete with the same strength grade.Increasing the dosage or extending the pre-wetting time of lightweight aggregate could improve the impermeability and damping of the concrete rather obviously.According to the SEM observing and pore structure analyzing results,mechanism of lightweight aggregate on the damping and permeability of high damping concrete was discussed.
