On the Young's Modulus of Different Form for Standard Size

Past reports have been said that there are not the clear tendency between Young's modulus and size of specimen. But, judging from the relationships of compressive test which was reported before in the Memoirs Yamaguchi University, effects on the size of specimen are recognized. Then, authors experimented under several proportions of concrete, ages and curings, and defined the elastic and elastic-plastic limit owing to their discussion for experimental stress-strain curves. We have the idea that each Young's modulus of specimen are the tendency of a straight line within elastic limit. It is not recognized that influences depend on concrete proportions and ages in accordance with study larger mainly than those of standard specimen under the water curing. The results of experimental research have mentioned in this paper.
