SOLUTIONS FOR STRUCTURAL AND THERMAL REINFORCEMENT OF MASONRY

The crm system: composite reinforced mortar Seismic Upgrading and Thermal Advantages: Sismactive Thermal System Sismactive thermal system: The components of an innovative solution CORK, THE RESILIENCE OF MATERIAL

THE CRM SYSTEM: COMPOSITE REINFORCED MORTAR THE SEISMIC UPGRADING OF MASONRY STRUCTURES AND BUILDINGS IS A MAJOR GLOBAL CHALLENGE. THE GOALS ARE TO PREVENT THE DESTRUCTIVE EFFECTS OF EARTHQUAKES, INVESTING IN PEOPLE’S SAFETY, ENHANCING AND RECOVERING EXISTING PROPERTIES IN SEISMIC PRONE ZONES. The CRM system – expressed in Diasen’s Sismactive Thermal System - offers an effective response to this widespread building conservation requirement. Improving on the traditional technique of reinforced concrete, its approach is aimed at seismic performance improvement and upgrading and structural reinforcement...

SEISMIC UPGRADING AND THERMAL ADVANTAGES: SISMACTIVE THERMAL SYSTEM Diasen interprets the opportunity of seismic upgrading through CRM systems with an original proposal: the Sismactive Thermal System. This innovative solution guarantees seismic and thermal insulation performances, enhancing all the benefits afforded by a multitasking system designed to meet the safety and comfort requirements of buildings. This is made possible thanks to the use of Diathonite Sismactive, an M10 structural thermal mortar formulated with cork and lime, developed to offer excellent performances in terms of the seismic...

MAXIMUM REVERSIBILITY THEREFORE SISMACTIVE THERMAL SYSTEM OFFERS ITS USERS SIMPLE, HIGH-QUALITY INTERVENTIONS WITH AN OUTSTANDING COMBINATION OF OPPORTUNITIES AND ADVANTAGES: MINIMUM THICKNESSES Unlike reinforced concrete mortar, which required considerable thicknesses (7-8 cm) to cover the electrowelded wire mesh, with the CRM system 3-5 cm is sufficient; 6 MINIMUM INVASIVENESS The application of the reinforced mortar just on the exterior of the masonry allows uninterrupted use of the building even during the intervention. MINIMUM RIGIDITY The limited thicknesses guarantee a negligible increase...

SISMACTIVE THERMAL SYSTEM: THE COMPONENTS OF AN INNOVATIVE SOLUTION THE FUNCTION OF THE MESH WITHIN THE SYSTEM IS RELATED TO ABSORPTION OF TENSILE STRESSES, WHILE THE M10 STRUCTURAL THERMAL INSULATING MORTAR FORMULATED WITH CORK AND LIME HELPS ABSORBING COMPRESSION STRESS FORCES. AT THE SAME TIME, THE CONNECTORS ARE DESIGNED TO STRUCTURALLY ANCHOR TOGETHER THE MASONRY AND THE MORTAR, EXPLOITING A STRESS TRANSFER MECHANISM BETWEEN THE SUPPORT AND THE MESH. The Sismactive Thermal System, in terms of its seismic and thermal properties, is closely linked to the balance of its components and the way...

BELOW ARE REPORTED THE KEY CHARACTERISTICS OF THE DIFFERENT SISMACTIVE THERMAL SYSTEM COMPONENTS: DIATHONITE SISMACTIVE It is a ready-to-use natural thermal insulating mortar formulated with cork (grain size 0-3 mm), NHL5 hydraulic lime and diatomaceous earth. Diathonite Sismactive is suitable for the consolidation of masonry structures and vaults, through the construction of reinforced repointing systems. This is a mortar with excellent mechanical strength. It is made of NHL 5 natural hydraulic lime, hydrated lime and natural aggregates, and it is ideal for the consolidation and renovation of...

This fibreglass mesh is used as a reinforcement material in CRM structural systems, providing global improvement of strength and flexibility. A preformed connector made of fibreglass with resin, designed for the structural reinforcement of masonry and suitable for the upgrading of buildings in seismic prone areas. Characteristics: Handy In conjunction with lime-based mortars, it creates a functional, high-strength system. Strength it has high tensile and shear strength Characteristics: Strength the alkalinity of the mesh is key to excellent corrosion resistance Primed Mesh performance is increased...

An AR fibreglass transversal connector designed for the structural reinforcement of masonry, arches and vaults. Characterised by a rigid preformed central segment and one or two tassel ends. A high-performance resin for anchoring heavy loads and seismic fixing, with excellent mechanical and thermal characteristics. It is ideal for the anchorage of fibreglass connectors in CRM structural reinforcement systems. Strength The tassel extremities ensure that the product is fully integrated in the limebased mortar. Thixotropy easy use in vertical as well as horizontal applications due to its non-drip...

MASONRY REINFORCEMENT ON ONE SIDE ONLY WITH “L”-SHAPED CONNECTORS DIATHONITE SISMACTIVE POLITES AR 330 ELITES L SISMABOND APPLICATION CYCLE • Wet the surface of the support and, if necessary, rebuild any parts of missing or damaged masonry. • Drill the holes for the connectors, inserting guides to help identify the holes subsequently. • Apply a first layer of Diathonite Sismactive, by hand or by machine, without covering the holes. • Partially anchor the Polites Ar 330 mesh in the fresh mortar. • While the mortar is still fresh, remove the 16 guides and inject the epoxy resin Sismabond into the...

MASONRY REINFORCEMENT ON TWO SIDES WITH “L”SHAPED CONNECTORS APPLICATION CYCLE • Wet the surface of the support and, if necessary, rebuild any parts of missing or damaged masonry. • Drill through-holes for the connectors, from one side of the masonry to the other, inserting guides to help identify the holes subsequently. • Apply a first layer of Diathonite Sismactive, by hand or by machine, without covering the holes. • Partially anchor the Polites Ar 330 mesh in the fresh mortar. 18 DIATHONITE SISMACTIVE POLITES AR 330 ELITES L SISMABOND While the mortar is still fresh, remove the guides and...
