Relationships of Strengths and Dimensional effect of Plastic Concrete

摘要

This article carried out the strength experiments on four hundred and five specimens with twelve mix proportions and three curing ages, systematically investigated the relationships of related strengths, the dimensional effect of compressive strength and splitting tensile strength of plastic concrete. The results showed that there well exist the statistical relationships among the related strengths of plastic concrete, the dimensional effect coefficients of compressive strength and splitting tensile strength with 100mm cubic specimen are 0.9375 and 0.8616 respectively compared with 150mm cubic specimen. Based on the analysis of test results, the conversion formulae of strength-related indicators and linear function relationship between axial compressive strength and curing ages are put forward respectively.
