Abstract

Construction is a large waste generator that is mostly disposed of in landfills or in irregular places, causing environmental impacts. Sustainable construction is an alternative that seeks to prevent and reduce waste generation by reducing, reusing and recycling. Recycling Construction and Demolition Waste (RCD) as aggregates of floor concrete can bring economic, technical and environmental advantages. The concrete floor has a longer durability than the others. This work aimed to investigate the waste generated in construction and demolition works in the city of Porto Nacional (TO) and its application as minute aggregates of concrete. The research aimed at results that allowed the verification of the behavior of the concrete in relation to its tensile strength and compression when submitted to what was proposed so that it could analyze its suitability for road use. The ceramic residues were characterized and evaluated according to the type of material, and the fine aggregates used, defined in the trace, had their replacement percentages set at 0%, 3%, 4,5% and 6%. Thus, through the tests that were performed, it was verified the possibility of substitution of natural small aggregates by ceramic recycled small aggregates in which some proved viable and quite advantageous not only for the environmental issue, but also in the resistance gain of the material.
