Study of influential factors on the rheological properties of Brazilian market adhesive mortars

Resumo

Rheology studies the flow of matter seeking to describe the deformation of materials depending on the time they are exposed to mechanical actions. This paper proposes an understanding of the behavior of fresh adhesive mortar, from the Squeeze flow test. In this test, the flow of material results from the application of a compressive load on the fresh sample. It was further performed the physical characterization of mortars and viscosity of the pastes. It was observed that the mortars studied showed differences in rheological behavior, probably due to synergistic action of parameters of the composition, especially the particle size distribution.
