摘要
本文分析了影响汾河二库碾压混凝土VC值的主要因素,总结出VC值与气温、相对湿度、停滞时间的定量关系,提出了VC值的事前控制办法。
In this paper,the main factors influencing the VC(vibrating compacted)value of roller compacted concrete,the Fenhe Reservoir Ⅱ are analyzed.The quantitative relations between the VC value and air temperature,between the VC value and relative humidity,and between the VC value and stagnation time that the mixed concrete came out of the outlet of batch mixer to time that the concrete starts to be rolled are summarized.A prior control measure of the VC value has been presented thereby.
