Committee Home

Committee Mission: Develop and report information on assessment, repair, rehabilitation, preservation, restoration, and strengthening for sustainable management of existing concrete and masonry structures.

Goals: - Develop a guide for rehabilitation and preservation of historic concrete. - Develop and maintain TechNotes to address issues concerning concrete repair and rehabilitation not covered by existing documents. - Provide liaison and promote interaction with other committees related to repair and rehabilitation. - Form a task group to coordinate the development of information on rehabilitation of masonry with the TMS (The Masonry Society) Existing Masonry Committee. - Maintain the Guide for Assessment of Concrete Structures before Rehabilitation (ACI PRC-364.1-19). - Maintain the Guide for Cementitious Repair Material Data Sheet (ACI PRC-364.3-22).
