Durabilidad del hormigón con fibras de yute.

Abstract

The present research article has the aim of study the durability of concrete; which is one of the most important aspects, relating it directly to the useful life of the structures. There are different aggressions, physical and chemical that affect the behavior of concrete. For the present study, seawater has been taken as a reference, since it is one of the main factors that causes destructive effects on concrete, due to the formation of calcium sulfate and calcium sulfoaluminiate, generating deformation in the structure because of the increase in its volume. This research integrates variables such as: resistance, unit weight, modulus of elasticity, absorption, porosity, important indicators for the study of durability. In this search, 40 standard concrete specimens and 60 concrete specimens were made, including jute vegetable fiber with resistances of 21 MPa respectively, which after curing at 28 days, 60% of the samples were subjected to immersion cycles in solution of Sodium sulfate and oven drying at 110 °C ± 5 °C, and then the corresponding mechanical tests were carried out. From the results obtained, a comparative analysis was made among all the concrete samples, confirming that the presence of sodium sulfate, affects the resistance and porosity for each type of concrete samples, being important aspects for the study of durability
