TRB’s National Cooperative Highway Research Program (NCHRP) 360: Rheological Characterization of Flow Table Reference Material summarizes the key findings of a project that characterized available batches of cement and concrete reference laboratory (CCRL) flow table reference material. The project also explored more efficient, stable, and reproducible methods for future production of the reference material that is independent of the CCRL flow table.
The contractor’s final report, which is summarized by NCHRP RRD 360, is available online.
