Analytic methods and theory of quantitative stereology for the determination of concrete proportioning in structural components

The analytic methods and the theory of the quantitative stereology combining with micro-analysis for concrete proportion on structural components were systemically described in this paper, specifically, the effective mix proportion of structural concrete was identified through three levels macroscopic (coarse aggregate), mesoscopic (fine aggregate) and microscopic (cement paste). Moreover, the porosity and hydration degree of structural concrete could be understood based on the compositional analysis of aggregate and cement stone. The results of the experimental analysis indicated that the mix proportion of concrete was similar to the effective mix proportion, the systemic error of the method could be amended, and the relative errors among configurations of materials were less than 4%, which validated the accuracy and the applicability of the methods.
