CHARGEDevelop a technical report on the characterization of mechanical behavior of cement and test methods to measure the mechanical parameters of cement in the laboratory. This TR is intended to serve as the basis of an ISO NWI.
ApproachCombined current methods used in industryCreated working documentUse cooperative testing to refine documentIdentify variancesSet testing protocols Apply limits when necessary Answer questions
Winter MinutesA presentation was reviewed that included:A summary of the results obtained in the first coop testing effortA large portion of the data has been collected for the second coop testing effort with the following notes: 7 labs have reported results Various load and displacement rates documented Different sample sizes used Various load frames and instrumentation used The next step is to combine the coop testing results and include them in an appendix within the working TR. This will be shared with TG along with recommendations for the document.
Summary of 2nd Round Robin7 labs reportedSeveral Parameters InvestigatedLoad Frame and InstrumentationDisplacement and Load Rates Splitting Sample Size Cyclic Loads Analysis Technique
Status of Working DocumentAppendix added containing round robin #2 results.Minor corrections made
Next StepsAdd Round #1 ResultsUse results to refine sections as necessaryMixingInstrumentation Load/Displacement Rate L/D ratio Etc. Determine if there is suitable supporting test data to have a reproducible procedure Finalize Document
