Abstract

According to current Greek and international regulations regarding repair of damage in concrete structures or masonry, epoxy based mortars can be used for these applications. In this paper, the mechanical behaviour of epoxy based mortars under typical laboratory testing conditions such as uniaxial compression, was simulated by means of finite element analysis of two-dimensional models. The analysis was performed in the elastic domain for the aggregates and the elastoplastic domain for the resin. Four elementary models were created and material model values were based on laboratory data. Comparative diagrams of stresses and displacements are presented and compared. The prominent failure mechanism is identified as plastic deformation of the resin material.
