CONCRETO PERMEÁVEL COM RESÍDUO DE CONSTRUÇÃO: VIABILIDADE E BENEFÍCIOS

Abstract

Contemporary urbanization has intensified the demand for new buildings, resulting in substantial volumes of construction-related solid waste. The progressive impermeabilization of urban areas has diminished stormwater infiltration capacity, thereby exacerbating extreme hydrological events such as flooding, which poses increasing challenges to the construction sector. Within this context, permeable concrete manufactured with recycled aggregates derived from concrete construction and demolition waste (CDW) represents a promising mitigation strategy. Its implementation, however, requires rigorous evaluation of technical, regulatory, and economic criteria, including structural performance, durability, permeability, and compliance with Brazilian standards.This study provides an overview—supported by a literature review and an analysis of relevant Brazilian regulations—of the technical and economic feasibility of incorporating CDW into permeable concrete as a means to reduce environmental impacts in the construction industry. The methodology combines hypothesis-oriented analysis with documentary research based on scientific databases, legislation, and applicable technical standards. Findings indicate that the use of CDW in permeable concrete is both viable and environmentally advantageous, contributing to improved urban drainage and the reduction of environmental liabilities associated with construction activities.
