摘要
塑性混凝土的抗渗性能是其主要性能之一,但目前尚没有统一的评价指标体系。通过对混凝土的各种抗渗性能指标进行研究及比较分析后,发现渗透系数物理意义明确,能较好反映塑性混凝土的渗透特性。稳定渗流法试验方法经过改进后,实验结果可准确反映塑性混凝土渗透性,同时结合允许水力坡降,确立反映塑性混凝土的抗渗性能指标体系。
Anti-permeability is among the most performance of plastic concrete,nevertheless the unified appraisal system hasn＇t been established.Through study and comparable analysis of anti-permeability performance index of concrete,it is found that the concept of permeability coefficient has clear physical meaning,and can reflect the characteristic of plastic concrete permeability preferably.Stability permeability methods are improved so that the experimental result can express permeability of plastic concrete well and accurately.Combining the allowable hydraulic slope,index system of plastic concrete impermeability is established.
