And it represents the main investment and the most important assets of middle and low income families. However, despite acknowledging its importance, the deficits recorded for the countries of Latin America are more than 25 million housing units (CEPAL, 1995) and to Ecuador, a requirement of 1 million, two hundred thousand solutions. The causes that prevent the provision of housing are associated with the unequal distribution of wealth, the high costs of building materials, and the dependence on technology and the lack of local research and ingenuity. Currently, the predominant use of concrete has led to the discovery of composite materials, achieved through the addition of fiber to the concrete matrix, aiming to reduce costs. In this case, the design of concrete was performed under the Maximum Density Method and utilized Iriartea deltoidea or Pambil as fiber reinforcement, which is readily available in the province of Zamora Chinchipe, located in the south eastern part of Ecuador. It was used in varying percentages of 0.50, 1.50 and 2.5% and whose sizes were retained in sieves 4 and 8, placed randomly in the concrete mix. The results obtained show that the addition of fiber elements tested under compression improves the characteristics of the composite. However, with regards to flexion the concrete strength decreases, showing not so encouraging results for the manufacture of composite concrete and fiber pambil. This adverse outcome does not guarantee the success of the composite concrete, which under experimental conditions is technically recommendable, but still does not prove to be economically advisable. |
