The last meeting of TC HFC was held in conjunction with the International Workshop on HPFRCC in Structural Applications in Honolulu, Hawaii in May 2005. The theme of the workshop was closely related to the working program of TC HFC and the workshop presentations were structured in the following Task Groups:
Summaries and conclusions of the Task Group presentations and discussions, and of the subcommittees meetings are available below to be downloaded for you information. Please note that conclusions of TG A and TG B coincide with those of SC 1 and SC 2, respectively. For more information on the HPFRCC workshop, please visit www.hpfrcc-workshop.org. The subcommittees held their meetings subsequent to the workshop and were based in part on the Task Group meetings. TC HFC is organized in three subcommittees:
TG A and SC1
Conlusion TG B and SC2
Conlusion TG C
Conlusion TG D
Conlusion TG E
Conlusion TG F
In the general meeting of TC HFC, the discussion focused primarily on the terminology used to describe cementitious composite materials with strain hardening and multiple cracking characteristics. The term HPFRCC, used in the past to characterize such materials, was based on a misinterpretation of a definition introduced by Naaman and Reinhardt in 1996 ("Characterization of high performance fiber reinforced cement composites - HPFRCC" in Proc., HPFRCC 2, pg. 1-23) and is now considered not sufficient to uniquely describe strain hardening cementitious composites.
Based on the discussion in TC HFC, the acronym SHCC (Strain Hardening Cementitious Composites) is suggested as an improved description. There is a consensus among a large part of the members of TC HFC that the term SHCC should be used in the future to refer to cementitious materials with strain hardening characteristics. Please contact Victor Li (TC HFC Chair) or Gregor Fischer (TC HFC Secretary) should you have any comments or questions on the issue of terminology.
The activities of the subcommittees in TC HFC for the projected duration of the committee are outlined in the attached summaries of the SC meetings. Should you be interested in contributing to the work of a subcommittee, please contact the respective SC Chair to indicate your interest.
