Abstract

Abstract

Strength and deformation were studied on plastic concrete in different loading ways through direct and cyclic loading and unloading testing.Conclusions have been drawn: Peak strength reduces generally through cyclic loading,and the degree of change is less than 10%,and the peak strength of cyclic loading and unloading of the maximum value of 60% uniaxial one is more than the others,stress-strain in loading condition does not conform with that in unloading.The area between curve of loading and one of unloading does not change with times of cyclic loading,and increases with increment of the maximum cyclic loading.The slope of the curve of loading is about the same as the one of unloading.The strain of peak strength increase through cyclic loading.
