Avaliação da utilização do agregado de concreto reciclado (ACR) em substituição ao agregado miúdo na fabricação de argamassas de concreto para pavimentação.

Abstract

The Amazon region has a large territory, where there are few economic centers with great distance from those of most developed country. Moreover, due to its geological formation, the main cities of the region not have material available that can be economically employed in construction. Moreover, the main capitals have displayed a high level of economic growth with an accelerated pace of new works with the consequent generation of waste construction. Thus, the technical solution for pavements with the use of construction and demolition waste is presented as an alternative technology of great economic and environmental interest. With the objective of obtaining parameters that allow an assessment of technical and economic feasibility of concrete made with the inclusion of construction and demolition wastes (CDW), specifically the RCA (recycled concrete aggregate), to the production interlocking pavers for pavement, in this work is presented a study of determination of its main mechanical properties, considering the partial replacement of the aggregate by the construction and demolition waste. In the development this work, we carried out tests of chareterizatian of the mechanical and physics properties concrete made with RCA, according to the Brazilian standards.
