Discover the technical characteristics of complete, certified systems for the repairing and strengthening masonry, the products, the fields of application, the advantages, the reference standards and the System acceptance guidelines.
The Ruregold CRM System has been issued with ETA 22/0078.
It has also been the subject of extensive experimental trials at the Materials and Structures Testing Laboratory of the Department of Civil Engineering and Architecture (DICAr) of the University of Pavia, conducted on natural stone masonry samples strengthened using different combinations of mortars, meshes and connectors from the product rang, with the aim of evaluating the positive effect of the various CRM strengthening systems applied to the unstrengthened original masonry, in terms of resistance and failure modes.
The experimental tests, conducted on a wide variety of samples, improved the understanding of the beneficial effects of the various components of the CRM system, while the test report issued by the University of Pavia provides a clearer picture of the advantages of the CRM System.
The monograph includes a detailed description of the experimental tests conducted by the University of Pavia.
ELEMENTS OF THE RUREGOLD CRM SYSTEM
FIBREGLASS MESH
STRUCTURAL MORTARS
NHL 3.5 lime base
Compressive strength ≥ 15 MPa
ETA:
European Technical Assessment EAD 340392 – 00- 0104 “CRM (Composite Reinforced Mortar) Systems for strengthening of concrete and masonry structures”.
Compressive strength ≥ 15 MPa
The Ruregold CRM System is completed by the connection system, consisting of HELICAL CONNECTORS
helical bars in stainless steel, or preformed A.R. fibreglass elements, the G-MESH GUSSETS for distributing stress concentrations at the connections, and the G-MESH ANGLE preformed angular element.
THE ADVANTAGES OF THE RUREGOLD CRM SYSTEM
INNOVATIVE SYSTEM
The G-MESH 400/490 system represents the transition from the traditional reinforced plaster technique to the CRM system, based on the use of preformed meshes in alkali-resistant composite material.
EXCELLENT PERFORMANCE
During the extensive experimental trials conducted at the University of Pavia, Ruregold strengthening systems achieved excellent results, even exceeding the indications set out the Regulations.
DURABILITY
G-MESH 400/490 meshes demonstrate excellent behaviour in alkaline environments.
COMPATIBILITY
Excellent compatibility with masonry walls., also ideal for historic and monumental buildings.
EASE OF INSTALLATION.
G-MESH 400/490 meshes, which are supplied in 40 m2 rolls, are highly manageable. Installation is quick and simple.
COMPLIES WITH CRM SYSTEM GUIDELINES
The Ruregold CRM System is fully compliant with the Guidelines introduced in November 2018 (European Guidelines) and May 2019 (Italian Guidelines).
The Ruregold CRM System has been issued with ETA 22/0078.
