Avaliação do comportamento mecânico do concreto incorporado com resíduos de construção e demolição – RCD

Abstract

The civil civilian chain is one of the human activities that consumes the most raw materials and a high production of waste. This is a process of environmental survival and scarcity of natural resources, the use of civil construction and demolition (RCD) resources in the composition of concrete, the most consumed material in the sector, is shown as an alternative to sustainable development. Therefore, a research had as objective to study a viability of wood residues application in the construction and demolition in the composition of the concrete. To do so, a character search was characterized as an exploratory study, the theoretical framework was developed, based on a collection of results, and was not considered as a property of concrete with RCD, produced by means of experimental, with A approach of quantitative and qualitative data, was not developed and was not lasting, was carried out from tests of tests: cone reduction, compressive strength, water absorption, voids index and mass. From then on, the application of the RCD of 25% of natural aggregate per RCD and of 145% to 50% of RCD can be recognized. For the other properties the results were satisfactory. In this way, an RCD application is feasible for the elaboration of a structural project.
