Utilização de concreto e argamassa de reboco com adição de resíduo de porcelanato e de cerâmica

Abstract

The civil construction scenario is also a cause of problems because it generates a lot of the environment, they do not cause problems, such as those that are discarded correctly, that do not serve correctly. Among several discarded materials, porcelain and ceramic waste have qualities that can favor the replacement of some components present in this industrial sector. In this way, this study mainly evaluates appropriate forms of reuse, where these materials can be aggregated, in the field of civil construction, mainly replacing mortars and concrete. The main focus of the present work was to evaluate the use of waste managed through ceramic coatings (ceramic and porcelain waste), as a replacement of sand for the manufacture of cement mortars and structural concrete. Two residues were evaluated, ceramic and porcelain, both generated by polishing the material and grinding and grinding it. These residues were characterized in terms of their granulometric distribution and chemical composition. To make the specimens, cylindrical shapes measuring 10x20cm and 15x30cm were used, in which they were molded and subjected to compressive strength tests after 28 days of curing. In addition to water absorption tests for mortars and concrete and Pull-off (adhesion) for cementitious mortars. The results show that there was an increase in the water/cement ratio both in the mortars and in the concrete produced, due to the use of materials (waste) that require a greater amount of water to have plasticity in the application of mortars and compactness. in the necessary concrete, thus producing a reduction of its intended compressive strength when compared to the traditional traits of mortars and concrete, and the mortars can be used mainly because of their lower cost and superior results of the current norms and the concrete must also be used by the obtaining a lower cost of traditional concrete and superior results of the current norms for non-structural purposes and for structural concretes for rural environments.
