Comportamento tensão-deformação de corpos de prova de Argamassa comprimidos axialmente

Abstract

The work studied the behavior stress-strain bodies of the test piece of mortar compressed axially, compression tests were performed on cylindrical bodies of the test piece and prismatic, justified the use of cylindrical to make it possible instrument them to perform reading of deformations with strain gauges when subjected to compression, and prismatic to study traction on bending were also analyzed modulus data, the influence of the mortar compressive strength of the stress-strain behavior, Poisson's ratio and specific volume variation. To make it possible to simulate the mortar confinement were two times body-specimens, and was also used two lines of mortar, a low resistance and other high strength which are also studied the variation in behavior stress-strain when modified trait. On the other hand, it was also carried out the same instrumented tests with a new procedure in order to identify possible variations in the results analyzed for the two cases, thus concluding that the second procedure offered more real and reliable results for the proposed work.
