Abstract
Cellular concrete has increased in popularity in the construction industry due to its particular characteristics. It is classified as lightweight concrete and its structural behavior is consistent with this definition, showing less rigidity and more brittleness compared to normal concrete. In this work, experimental results obtained through bending tests on hybrid beams formed by two layers, one of normal concrete and the other of foamed cellular concrete, reinforced with polypropylene fibers, are presented. In this way, it was sought to increase the rigidity of the elements subjected to bending, through the incorporation of the normal density concrete layer and, in addition, to reduce the fragility of the foamed cellular concrete, through the addition of polypropylene fibers. Furthermore, the interface between both layers was treated with chemical glue for concrete, to achieve a better structural behavior of the elements. Characterization of the materials used was also carried out. In this way, the mechanical properties of the different concrete are analyzed and compared and the bending behavior of the hybrid beams is evaluated. Conclusions are drowned
