骨料细沙对混凝土水化反应影响的液态簧振动力学谱检测与分析

Detection and Analysis of the Effect of Sand Aggregate in Concrete Hydration by Reed-vibration Mechanical Spectroscopy for Liquids

采用液态簧振动力学谱(RMS-L)方法,对掺有骨料细沙的混凝土水化反应过程进行了力学谱检测,同时作为对比,对未掺骨料细沙的水泥浆水化反应过程也进行了力学谱测量与分析.结果表明,混凝土和水泥水化反应都至少经历了i至v过程.而骨料细沙的掺入,使得混凝土的水化反应显著加快,同时也提高了其反应度.因此,RMS-L方法可以对混凝土水化过程中骨料的影响进行灵敏的检测和研究,为骨料对水泥水化反应影响的研究提供了一种新的思路和方法.

The hydration of concrete mixed with sand aggregate was detected by reed-vibration mechanical spectroscopy for liquids （RMS-L）, and as a contrast, the hydration of cement pastes that has not mixed with sand aggregate was detected and analyzed as well. The results indicate that both the concrete and cement pastes experienced process i to v. The hydration of the concrete got obviously faster because of the doped sand aggregate, and the degree of reaction was enhanced as well. Hence, the effect of sand aggregate in concrete hydration could be detected and studied by RMS-L, and it can offer some new idea and method to the relevant research.
