| Sumario: | [EN] The use of recycled materials is becoming increasingly widespread in the field of construction. The high volume of raw materials used for the manufacture of construction products has made the use of materials out of use for the manufacture of new materials arises. And it promotes sustainable construction, reducing the environmental impact. Given the increasing use of fibers to reinforce concrete, incorporating recycled fibers to replace them or manufacturing new types of fibers from wastes to reach the possibility of getting behavior, if not the same, similar to the trade standard fibers. The motivation for this work is the study of the feasibility of using recycled synthetic fibers from waste, big bags, covers agricultural greenhouses, etc. This product type are used for transporting other products and in agricultural activities and involves a large volume of material that goes directly to landfill. They are made with synthetic fibers of polypropylene material with some commercial fibers for concrete are made. This presents an advantage over fibers made from PET having durability problems because of the alkaline nature of the concrete. One of the possible applications of these fibers is the control of shrinkage cracking of concrete. Currently, one of the most commonly used to control shrinkage cracking methods is the inclusion of fibers in the concrete mass which are distributed homogeneously. These fibers are about 31μm diameter and 12 mm length so that allow to include a large number of fibers per m3 of concrete. The effect produced on the concrete is to prevent the free movement of water to the surface, which is one of the main reasons for the retraction occurs. The phenomenon causes retraction concrete cracks affecting the durability of structures because it facilitates the penetration of aggressive agents that can damage the concrete and reinforcement itself. Since the recycled synthetic fibers have a granulometry in which a large number of similar to commercially used for fiber shrinkage control exists, a work project is presented to characterize the behavior of these fibers against this phenomenon. Because of the discontinuous granulometry of recycled synthetic fibers, another aspect is to study the mechanical behavior of concrete reinforced with fibers. In case of reaching a favorable outcome, would be taking into the market potential of a product that would be a significant contribution to the environment, since plastic waste pose a significant volume to total waste. Getting incorporate recycled materials, not only it is given a new life to waste, but lower consumption of virgin raw materials is encouraged, reducing the environmental impact involved |
