Composites with Inorganic Matrix for Repair of Concrete and Masonry Structures
|Publication Date:||1 April 2018|
This SP is the result of two technical sessions held during the 2017 ACI Spring Convention in Detroit, MI. Via presentations and the resulting collection of papers, it was the intention of the sponsoring committees (ACI Committees 549 and 562 together with Rilem TC 250) to bring to the attention of the technical community the progress being made on a new class of repair/strengthening
The terminology adopted in ACI to identify this class of new products is FRCM (fabric reinforced cementitious matrix) when the reinforcement is made of man-made fibers and SRG (steel reinforced grout) when the reinforcement is made of ultra-high strength steel. While it is recognized the other organizations and professionals may refer to these systems with different acronyms and names (for example, TRM for textile-reinforced mortar, TRC for textile reinforced concrete), ACI Committee 549 has made the conscious decision to adopt FRCM and SRG to unequivocally identify systems solely intended for repair and strengthening as opposed to new construction.
The two technical sessions and the resulting Special Publication were also the first tangible outcomes of the partnership between ACI Committee 549 and Rilem TC 250 that has as its ultimate objective, jointly producing a design guide for the repair/strengthening
The editors of this SP are most grateful to the technical sessions presenters and the authors of the papers for having shared their precious knowledge. The editors hope that this SP will be a relevant contribution to the deployment of suitable technologies for the safe preservation and use of existing concrete and masonry structures.
