摘要:
开展矿物掺合料混凝土的电阻率测定、抗氯离子渗透和立方体抗压强度试验,以分析研究电阻率和氯离子扩散系数随龄期的变化规律,混凝土电阻率和氯离子扩散系数间的相关关系.试验结果表明:混凝土电阻率随龄期的增长而增加,氯离子扩散系数随龄期的增长而下降,矿物掺合料双掺效果优于单掺.氯离子扩散系数随电阻率的增大而下降,两者之间呈良好的倒数回归关系.
Abstract:
Rsistivity measurement，resistance to chloride penetration and cube crushingstrength of mineral admixtureconcrete are tested to analyse the variation of resistivity andchloride diffusion coefficient with age and theregression relationship betweenresistivity and chloride diffusion coefficient．Testresults showthat con— crete resistivity increasedwith the increase ofconcrete age and chloride diffusioncoefficientdecreasedwith the increase of concrete age．The effect of double mixing mineral admixture is better than that of single mixing．Chloride diffusioncoefficient increasedwith the decrease of concrete resistivity and has agood inverse regression relationship with each other．
