摘要
自密实混凝土用作隧道防水是一项有效的措施。试验以某高速公路隧道工程为背景,采用透水法和氯离子扩散系数法对自密实防水混凝土和普通混凝土的抗渗性能进行比较,并分析养护时间、水灰比、粉煤灰掺量等对混凝土抗渗性能的影响。
Self-compacting concrete used for tunnel waterproof is an effective measure.This experimental study is based on an engineering of highway tunnel and comparisons are made between self-compacting concrete and normal concrete on impermeability with water permeability and chlorion diffusion coefficient methods.The influence of curing time,water/cement ratio and content of fly ash on impermeability of concrete has also been analyzed.
