CONCRETE ANALYSIS

Within the construction sector, concrete is one of the most used materials, being a mixture of cement, coarse and fine aggregates, water and in some cases additives are added. A new alternative in the manufacture of this material are construction waste class A as aggregates, this way can lead to a reduction of discarded materials, reducing environmental impacts. It is also necessary to highlight the need for analysis in situationsde incêndios, visando definir o estado da estrutura após ser exposta ao fogo. In this sense, this paper addresses the study in fire situation of concretes produced with civil construction waste class A. For this, a mix was defined by replacing 50% of the gravel by CCR as coarse aggregate, and its properties were analyzed at certain temperatures. In general, the analyzed concrete did not show good behavior compared to conventional concrete.
