Analysis of Mechanical Strength Concrete with Addition of Fiber PAMBIL

Abstract:

In the second decade of the twentieth-century housing still plays a decisive role in the quality of life of the population of the countries in the developing world and it represents the primary investment and the most important assets of middle and low-income families. However, despite acknowledging recognizing 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 accommodation 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 real matrix, aiming to reduce costs. In this case, the design of concrete 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 southeastern part of Ecuador. It used in varying percentages of 0.50, 1.50 and 2.5% and whose sizes 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, about 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 …
