UTILIZAÇÃO DOS RESÍDUOS SÓLIDOS DA CONSTRUÇÃO CIVIL: ensaios comparativos de resistência entre agregados minerais e produtos reciclados

Abstract

The transformations that have occurred on the planet have demanded changes in behavior, as man has caused huge impacts on the environment, causing the exhaustion of ecological and climatic systems. Civil construction has a relevant contribution from the point of view of progress in basic sanitation, supply of drinking water and energy for the populations, with works of reservoirs, hydroelectric plants. However, it also contributes to the generation of solid waste. It is public knowledge and that of the government and private sectors of environmental management that, especially in large centers, the volume of debris from civil construction is considerable. Just as it is through Engineering that a large part of the solutions to the problems and needs of man in their social and economic development as a whole are elaborated, it is expected that more and more alternatives will emerge to solve and mitigate the impacts generated by the RCD - Construction and demolition waste. A viable solution to comply with the legislation, as a mitigating action for the problem of accumulation and inadequate disposal in the environment in relation to the RCD, will be the treatment of waste in order to be recycled allowing the reuse in civil construction works. In order to satisfy the doubt regarding the equivalence between the use of RCD and traditional aggregates in concrete, this work evaluates, through tests of compressive strength in the specimens, comparing them with the traditional mineral aggregates. The adopted method was initially of bibliographic research and articles about the RCD and in literature related to the theme and compression tests in concrete specimens with traditional mineral aggregates and RCD aggregates and the execution of tests. After the execution of the predicted tests and the respective results records, it was evidenced the existence of a discrepancy in strength of the concretes of 1st composition and 2nd composition. Thus, after analyzing the results, it is concluded that the recycled aggregates can be added in non-structural concrete.
