Estudo da Gestão e principais aplicações dos Resíduos da Construção Civil (RCC)

Abstract

The Civil Construction sector stands out as the largest consumer of natural resources and generates solid waste, explained by the advance of urbanization associated with the emergence of new buildings. According to Abrelpe, in 2018, 122,012 t / day of construction waste (RCC) were collected in Brazil, which are those resulting from construction, renovation, repairs and demolitions, and those resulting from the preparation and excavation of land. According to CONAMA Resolution No. 307, waste management consists of a system that aims to reduce, reuse or recycle waste. RCC management aims to improve urban cleanliness, reduce costs, ease the disposal of small volumes generated and the disposal of large volumes generated, environmental preservation, incentives to partnerships and reduction of generation. Even though it is an incipient process, the recycling of materials is being an efficient mechanism to minimize the problems arising from the non-management of RCC. Several studies have evaluated the technical and economic feasibility of using RCC in the production of aggregates used in paving, in the production of concrete without a structural function, mortar, among others. Thus, this work carries out a survey of secondary data on the main uses of construction waste and an overview of management and generation in Brazil.
