| Popis: | It is clear, the great impact that the latest advances in the field of nanomaterials is having in the scientific community The possibilities of graphene and its derivatives are endless, since it has qualities never found before in another material, such as better electrical conductivity that of copper, and a resistance and flexibility between 100 and 300 times greater than steel. Although carbon nanofibers (CNFs) are used mainly in the field of technology, research is beginning to study the behavior of concretes with CNFs and that they show a better resistance to flexion, an increase in ductility, a better control of microcracks. and an improvement in compression resistance at early ages, while the incorporation of polypropylene fibers into concrete is a well-known result. The objective of the present investigation is to study the mechanical compression behavior in concrete with hybridization of fibers and compare it with traditional concretes. For this, cylindrical concrete specimens were made with hybridization of carbon nanofibers (CNFs) and polypropylene fibers, with 1% by weight of cement of each type of addition and cylindrical concrete specimens without additions, according to the results obtained it can be seen that the hybridization of the fibers does not represent a great advantage in the compression strength of the concrete, but it implies an improvement in the ductility of the same. |
