Análise de pisos intertravados de concreto com substituição de agregado miúdo por borracha

Abstract

Concrete is one of the most used materials for civil construction, its mechanical properties are fundamental for the construction of a building, its production requires a diverse number of materials, causing a great demand for resources. Seeking to reduce the consumption of one of the materials, fine aggregate, the objective of this work was to elaborate and study a concrete with partial replacement of fine aggregate by crushed rubber, resulting from the tire retreading process, with interlocking floors being made, known as blocks for analysis. behavior in the face of mechanical stress. As a test study was carried out, the replacement percentages of 4% and 6% were defined. Previous research has shown that along with the reduction in fine aggregate, there is also a reduction in compressive strength, in return, an increase in toughness. The results obtained are promising, the compressive strength complied with the established by the standard, even with the already expected reduction, along with the increase in toughness.
