Mechanical analysis of concrete produced with cdw aggregates associated with the use of bamboo

In the current scenario, it is necessary to develop sustainable constructive practices. The use of Construction and Demolition Waste (CDW) is an alternative to minimize the environmental impacts caused by civil construction, because, in addition to exploiting many resources, this industry generates a lot of waste. In contrast, it is observed that there is a decrease in the compressive strength of concretes produced with CDW. In this sense, bamboo appears as a possibility to mitigate these losses, in view of its high mechanical resistance. In this way, this research had as general objective to analyze the influence of the use of bamboo on the compressive strength of concrete produced with CDW aggregates as coarse aggregate. A bibliographic research was done, followed by an experimental research, being molded and submitted to the compressive strength test concrete and bamboo specimens filled with concrete, both with the following variations in the substitution ratio of CDW aggregates: 0% (reference concrete), 25%, 50%, 75% and 100%. Bamboo samples were also submitted to the test without adding concrete. The main results of the research point to the gradual loss of compressive strength of the concrete, but the use of recycled aggregate for concrete production up to the percentage of 25% has proved feasible. In turn, the association of concrete with CDW to bamboo was insignificant, since the bamboo culm without concrete showed superior resistance. In addition, in the samples filled with concrete, there were no relevant variations in resistance according to the CDW content incorporated into the concrete.
