AN EXPERIMENTAL STUDY ON CRITICAL DIFFERENTIAL MOVEMENTS IN DELAMINATED SITUATIONS OF CEMENT MORTAR RENDERINGS BONDED ON CONCRETE BODIES

Abstract

For the purpose of evaluating critical differential movements between cement mortars and concrete bodies, material thickness of mortar finishings bonded on concrete were experimented herein. As a result, regardless of the thickness, cement mortar finishings were exfoliated by interface fracture. The exfoliation point are clarified between strains of concrete and finishings. Furthermore critical movements were evaluated on addition of potential performance to deformation of finishings.
