弯曲荷载影响粉煤灰混凝土碳化规律的研究
Research on Carbonation Rule of Fly Ash Concrete Influenced by Bending Load
摘要
Abstract
Based on the accelerated carbonation test of fly ash concrete under load, carbonation velocity of concrete under bending load was investigated. The experiment results indicate that the concrete carbonation depths under the bending tensile (compressive) stress are larger (smaller) than the concrete carbonation depths under the non-stressing condition. By virtue of the bending stress coefficient of concrete carbonation, the influence of stress levels on concrete carbonation was analyzed. The bending stress coefficient of concrete carbonation and stress levels are consistent with quadratic polynomial quadratic.关键词
