Use of Mortar Plaster and Reinforcement For Repairing and Stiffening of Non-Structural Masonry Walls

Abstract
Many constructions built using the techniques of daub, paving clay or adobe have presented many pathologies and sometimes even risk of ruptures of some walls. In order to reinforce such walls, it is suggested in this work the use of mortar plaster, or reinforced mortar plaster with welded steel mesh, applied to the wall with non-structural blocks.Nine walls were tested for compression, being three walls of non-structural blocks without mortar plaster, three walls withmortar plaster and finally three walls with the same blocks plastered with reinforced with welded steel mesh.Three specimens had the dimensions of 1.20 m by 2.60 m andthe other six, called small walls,had dimensions of 0.90 m by 1.04 m. Simple compression loads capacity were obtained and it can be concluded that the application of the mortar plaster substantially increased the load capacity of the walls, as compared to the walls without mortar plaster.An increase of up to eight times in the rupture load was observed. The tests performed with the walls containing welded steel mesh inserted in the mortar plaster were not conclusive, although comparing them with the walls without mortar plaster, there was also gain of significant mechanical resistance.
