Análise das propriedades físicas e mecânicas do concreto com substituição parcial da areia pela cerâmica vermelha de Resíduos da Construção Civil (RCC)

Abstract

The construction industry is responsible for much of the country's economy, but on the other hand it consumes about 20% to 50% of natural resources, as well as being a major waste generator. Waste generated from losses during the process or from demolitions often has inadequate disposal, further increasing the environmental impact caused by the sector. Based on this information, this work seeks to bring an alternative to the use of red ceramics in the production of concrete. By means of tests with substitution levels of 15%, 30% and 45% and comparisons with the pilot trace, all of them met the minimum resistance expected. The trace with a substitution content equal to 45% reached 22,4 MPa when subjected to the compression test. Thus, for the studied properties, the use of this material in the production of conventional concretes was satisfactory.
