RESEARCH ON CARBONNATION OF FLY ASH CONCRETE UNDER BENDING LOAD

摘要：

Based on the accelerated carbonation test of fly ash concrete under load,carbonation rate of concrete under bending load was investigated. The experiment results indicate that the concrete carbonation depths under the bending tensile (compressive) stress are bigger (smaller) than those under the non-stressing condition. By virtue of the bending stress coefficient of concrete carbonation,the influence of stress levels on concrete carbonation is analyzed,and the relationship of bending stress coefficient of concrete carbonation and stress levels can be expressed by quadratic polynomial.
