Determinación de las propiedades físico-mecánicas en mampostería de ladrillo con morteros de junta

Abstract

In the context of the construction development of the city of Cuenca, the materials used date back to various periods, highlighting the use of masonry bricks and both mixed and cementitious mortars. The evaluation of the physical-mechanical properties of these materials is carried out through laboratory tests to identify their characteristics and behavior. This study focused on the use of Portland cement, graded sand and lime in conjunction with brick masonry from Sinincay (Cuenca) and Susudel (Oña). One of the challenges identified in Cuenca is the lack of mathematical models developed to estimate the compressive strength of masonry prisms. The normative framework used included ASTM C109(2016), ASTM C1314 (2021) and ASTM E477 (1997), which guided the execution of the tests. In addition, for the compression tests of bricks and masonry prisms, plywood was used on the top and bottom faces. Several mathematical models were evaluated and the approaches proposed by Hendry and Malek (1986), Bröcker (1963), Bennet et al. (1997), Dymiotis and Gutlederer (2002), Kumavat et al. (2016), Lumantarna et al. (2014) showed consistency with the results obtained in the laboratory tests, providing a solid basis for the accurate estimation of the compressive strength of the prisms with the materials and reality of Cuenca.
