Determinación del módulo de elasticidad de mampostería de bloque no estructural utilizada en la vivienda ecuatoriana

Abstract

In this project a study based on construction permits nationwide in the period 1991-2015 is performed, identifies the block is the material used in the construction of masonry in Ecuador. Samples are taken block for pre testing compressive strength in gross area, the value obtain was 20.9 kg/cm2, in addition the block was categorizing as structural and type B. Five volume dosages for mortar was made with cement-sand ratios (1-3, 1-4, 1-5, 1-6 and 1-7). It is established that the relationship 7-1 resistance reaches 30.2 kg / cm2, this dosage is sectioned for the study in this project. The non-structural block processing of 15 cm was verified in a factory. The moduli of elasticity were obtained with experimental testing and further processing of data is: 4736 kg/cm2, 1 389.8 kg/cm2 and 959 kg/cm2 for mortar, block and masonry respectively. Finally, an analysis of the test procedures and data processing for obtaining curves of stress-strain, and modulus of elasticity of mortar, block and masonry is performed, optimizing the assay process.
