| 摘 要： | 脆性是目前高强混凝土研究的关键问题之一.然而,迄今为止,脆性指标并不一致.现有大多数脆性指标的最大缺陷是显著受试件尺寸的影响而不能真实反映实际结构中材料的脆性.基于强度尺寸效应,可得出-与试件几何形式无关的材料脆性指标.该指标真实可靠,测定简单方便.

| Abstract: | The brittleness is one of the key important issues of the high strength concrete.However,there are not consistent brittleness indexes by now.The important shortcoming of the most brittleness indexes is that those indexes are influenced by size of testing sample.Therefore,they can not be used to image the true properties of the material in practice.Based on size effect of strength,the brittleness indexes,which can be obtained easily and are independent of size of the sample,can be reliable and have a great applied prospect. |
