Method for determining performance of high-fluidity concrete in tunnel lining

The invention belongs to the technical field of concrete testing, and discloses a method for determining the performance of high-fluidity concrete in a tunnel lining. The method comprises the following steps: measuring the meaning and slump value of medium-high-fluidity concrete, measuring the slump expansion value, measuring the expansion time, and comparing the measured test result with a prepared standard value to judge the working performance of the medium-high fluidity concrete. The method for evaluating medium-high-fluidity concrete in the tunnel lining facilitates improvement of the compactness of a tunnel lining vault and scientific and objective evaluation of the workability of the concrete, makes the mixed medium-high-fluidity concrete adapt to the construction characteristics and economic requirements of the tunnel, and provides reference and foundation bases for engineering projects needing to meet the economic and high-quality requirements at the same time in the future. 本发明属于混凝土测试技术领域，公开了一种隧道衬砌中
