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.
