Structural reinforcement: the CRM technique – Composite Reinforced Mortar

Why and when to use the CRM technique?

In Italy, the use of innovative materials for the structural reinforcement of existing buildings and structures is increasingly spreading. However, having a detailed knowledge of all the application techniques, often referred to by acronyms, is not always guaranteed. This is the case with FRP (Fiber Reinforced Polymer), a reinforcement technique that involves the application of fabrics and laminates made of glass, carbon, and aramid fibers with thermosetting resins; FRCM (Fiber Reinforced Cementitious Matrix), which involves the use of fabrics or nets made of various fibers applied with inorganic matrices (mortars); and CRM (Composite Reinforced Mortar), an intervention technique that uses preformed fibrous reinforcements and inorganic mortars, which will be the focus of this short article.
