SUMMARY:

The removal of natural resources and the increase in waste generation by the construction industry cause social and economic problems worldwide. This research seeks to investigate the feasibility of using ceramic construction waste (C&D) in the manufacture of pavers as a sustainable alternative for the industry. Through a comprehensive literature review, it was found that pavers produced with C&D can exhibit good compressive strength, low water absorption, good permeability, and adequate durability. The use of waste in concrete contributes to reducing the extraction of natural resources and reducing waste in landfills, demonstrating the potential of recycling C&DW, promoting the circular economy and reducing the environmental impact of construction. This study analyzes the impact of replacing conventional aggregates (sand and gravel) with construction waste (C&DW), maintaining the quantitative ratio (1:2:3) for cement, fine aggregate, and coarse aggregate, and maintaining a constant water/cement ratio. The materials used will undergo pycnometry, granulometry, optical microscopy, and X-ray diffraction tests to verify their properties, such as density, particle size, macrostructure, and crystalline phases, respectively. Four concrete mixes (T1 to T4) will be studied, following the specific standards for the manufacture of interlocking paving, based on ABNT NBR 9781: Concrete Paving Components – Specifications and Test Methods Preparation. The concrete prepared for forming the test specimens will have specific proportions, and characteristic compressive strength and water absorption tests will be performed. Additionally, a test will be conducted to verify the paver's permeability, as described in ABNT NBR 16416:2015 - Permeable concrete pavements — Requirements and procedures. The method determines the pavement's permeability coefficient by measuring the site's water infiltration capacity. This work is expected to identify the composition and process used to produce pavers using RCC with similar or superior quality to commercial products, thus contributing to the environmentally responsible construction sector.
