| Abstract: | In order to ensure the reliability of the assessment of compressive strength of concrete,National Center for Quality Supervision and Test of Building Engineering had organized and carried out many rounds of“Assessment of compressive strength of concrete”proficiency testing project to understand the industry level and identify technical risks.According to the practical experience of that project,this paper analyzes some technical problems in the assessment of compressive strength of concrete from the aspects of the determination of inspection batches,the identification and treatment of abnormal values of core sample strength,the determination of presumed interval of inspection batches,the understanding and use of sampling method,measurement sampling inspection method and the total revised quantity method,and gives some suggestions for improvement. |
