MX-PVA FIBRE-REINFORCED
High performance mortar for the structural restoration of walls with polyvinyl alcohol fibers
MX-PVA Fibre-reinforced is a premixed mortar based on a high pozzolan hydraulic binder and low salt content, select aggregates, additives, and polyvinylalcohol fibers.
Its particular composition excludes the possibility of chemical reactions with salts (sulphates, carbonates, nitrates, chlorides, etc.) present in the walls of old buildings.
Following the addition of water, a highly adhesive, thixotropic mortar without shrinkage is obtained. It is durable and suitable to improve the ductility and toughness of masonry structures.
It is ready to use: just add water to obtain a thixotropic mixture with no bleeding or segregation phenomena. It can be applied by trowel or spray.
In cases where a high aesthetic quality of the surface is required, use a suitable finishing coat.

THE STRUCTURAL PVA FIBERS
The structural PVA fibers provide resistance to the composite material, modifying the stress-deformation ratio. The three-di-mensional contribution of the fibrous reinforcement is particularly noticeable in the post-cracking phase, considerably increasing the material's ability to absorb energy and slow down the crack-ing process. It follows that MX-PVA Fibre-reinforced effectively replaces the use of the reinforced slab with reinforcement mesh, con-siderably reducing the thickness (only 3 cm compared to 7 or 8 cm needed for a standard reinforced slab).
