The first round comparative test results in five labs were summarized and analyzed in this file.
Based on the test results in the 1st round comparative test, we update the 2nd round comparative test program. The key points that need to pay attention to were marked in red.
We have five labs participating in the 2nd round comparative test now. Hopefully, more laboratories volunteer to join the comparative test program to make the results more reliable.
The fourth WG4 meeting of RILEM Technical Committee 281-CCC is planned to be held online on Tuesday 23 March 2021. All WG4 members are invited to join the meeting. The five labs participated in the first round of the comparative test are invited to have a 10~15 mins presentation to report the test results. It is hoped that all members will have an in-depth and extensive discussion of the results.
