Influencia del enlucido en la resistencia de paredes de mampostería.

Abstract

The objective of this investigation is to study the influence of plastering on the resistance of masonry walls by incorporating cement base mortar as a wall coating. In this sense, one fourth scale walls were built where a cement base mortar plastering was applied to a group of elements on each side of the wall. The plastered and unplastered walls were subjected to different tests to obtain the compressive, tensile and flexural strengths. These tests aim to model the behavior of the walls for the expected load condition like gravitational or seismic loads. The results show that plastered walls have better behavior and provide greater resistance. In the case of gravitational loads, the difference is not very important; but for the case of seismic behavior, especially out of the plane, the difference is significant.
