| Abstract: | On the basis of statistical theory,the distribution probability of full graded concrete strength and the relation between the sample size and coefficient of variation are introduced.According to statistical analysis of the strength ratio of full graded concrete to wet screened concrete,the probability distribution and confidence level of the ratio are obtained,which can be used in engineering practice. |

| Keywords: | full graded concrete statistical analysis strength confidence level sample size |
