摘要:
通过开展掺矿物掺和料混凝土力学和耐久性能指标的试验测试,研究不同龄期混凝土氯离子扩散系数与单方水泥用量、单方胶凝材料用量、立方体抗压强度、碳化深度以及动弹性模量间的相关关系.试验结果表明:单方胶凝材料用量与84 d龄期混凝土氯离子扩散系数线性相关性良好；混凝土氯离子扩散系数均随立方体抗压强度的提高而降低,84 d立方体抗压强度与不同龄期混凝土氯离子扩散系数线性相关性良好；混凝土氯离子扩散系数均随碳化深度的提高而提高,碳化深度与84 d龄期混凝土氯离子扩散系数线性相关性良好；不同龄期混凝土氯离子扩散系数均随84 d龄期动弹性模量的提高而降低.
Abstract:
Through test on mechanical and durability index of concrete with supplementary cementitious mate-rials,the correlation of chloride diffusion coefficients at dfferent ages with cement amount per cube meter, ce-mentitious materials amount per square meter,cube crushing strength,carbonation depth and dynamic elasticmodulus are studied. The test results show that 84d chloride diffusion coefficient has a good linear correlationwith cementitious materials amount per square meter. Chloride diffusion coefficients at different ages all re-duced with the increase of cube crushing strength,and chloride diffusion coefficients at different ages all havea good linear correlation with 84d cube crushing strength. Chloride diffusion coefficients at different ages allincreased with the increase of carbonation depth,and 84d chloride dffusion coefficient has a good linear corre-lation with carbonation depth. Chloride diffusion coefficients at different ages all reduced with the increase of84d dynamic elastic modulus.
