Hormigón con áridos reciclables procedentes de residuos de construcción

Abstract

This work analyzes the behavior, under compressrve stresses, of recycled concrete and conventional concrete, with previously classified and analyzed rubble obtained from the municipal dump of the Azogues canton, to recommend or discard the use of ecological concrete in structural and non-structural elements where it is required. For the elaboration of the ecological concrete tests, previous activities were conducted such as the selection, classification, and crushing of the rubble used in the tests, then the physical-mechanical properties of the recycled aggregate were defined, such as volumetric weights, granulometry, hurnidity, absorption; necessary for the elaboration of the concrete The results of the tests of conventional and ecological concrete were compared according to the water/cement ratio and the percentages of natural and recycled aggregates applied in each of the specimens tested. The application of ecological concrete presents an advantage in terms of cost and environmental mitigation; although the resistance conditions are not superior to those of conventional concrete, it can be said that the use of ecological concrete can help significantly to mitigate environmental affections, taking into account the acceptable quality in terms of compressive strength that it possesses.
