Estudio de comportamiento de un diseño de mezcla de concreto con adición de material reciclado de llantas.

Abstract

The mix designs are competent systems by competent theoretical-practical foundations that allow the calculation of the corresponding dosages to produce concentrations corresponding to a compressive strength for a given age with physical-mechanical properties suitable for its correct durability and stability in the fulfillment of its service time in the field. Because of the above mentioned is that technological and development fields such as academia offer research products annually that compete additional materials and mix designs in order to offer different conclusions that respect the advantage or not of certain designs or additive materials in the internal structure of a concrete (Osorio, 2019). This research project was executed with the objective of analyzing the physical-mechanical behavior of a mix design in with two types of mixes, a mix design established through the laboratories performed to determine the design composed of coarse aggregates, fines, water and cement; and an altered mix design (coarse aggregates replaced in three percentage mixes by recycled tire material), where a clear range of structural advantages were evidenced by the mix design without replacement of the coarse aggregate, such as its high resistance to compression, bending and modulus of elasticity, and in the second moment it was evidenced that the modulus of elasticity can be improved with the replacement of coarse aggregate by rubber in a small amount.
