通过对混凝土RCM试验结果的分析总结,利用线性回归分析数学手段,认为水胶比、粉煤灰和矿粉掺量与氯离子扩散系数有很好的线性相关性.建立水胶比、粉煤灰和矿粉掺量多因素共同影响下的氯离子扩散系数模型,并结合JGJ—2011《普通混凝土配合比设计规程》和龄期衰减系数模型,提出一种新型高性能混凝土配合比设计方法.
Through the analysis of RCM test results, linear regression analysis of mathematical means that the water-cement ratio, fly ash and slag content and chloride ion diffusion coefficient has a good linear correlation.A water-cement ratio, pf In this paper, a new type of high performance concrete mix design method is put forward based on JGJ-2011 “Specification of Mixture Design of Ordinary Concrete” and age attenuation coefficient model.
