DETERMINACIÓN DE LOS PORCENTAJES ÓPTIMOS DE FIBRA DE VIDRIO PARA HORMIGONES DE BAJA, MEDIANA Y ALTA RESISTENCIA

Abstract

Nowadays in the world, the most used construction material is the reinforced concrete. This is required for the construction of housing, roads, buildings; itself, a number of civil works that merit a durable material, which also provide security and durability. The resistance of this element is measured in kilograms per square centimeter; in easy terms, how many kilograms of force are supported by a square centimeter of area until the rupture. The concrete may have different types of strength, which have to do with the aggregates that are being used. This, is basically made up of water, sand, stone and cement, but he human being is always experiencing replacing or adding other aggregates in the conventional formula. This research project is adding fiberglass to a conventional concrete design. The strength used for this research will be of one hundred ninety kilograms per square meter, two hundred and ten kg per square meter, two hundred and ninety kg per square meter, and three hundred and fifty kilograms per square meter. Why adding fiberglass to a conventional concrete? As is known, the concrete is the main material used in civil works by different factors (resistance, cost, workability, durability, etc.), it is expected that with this fiber material, that the resistance to compression increase. Why these strengths are used to perform this experiment? In common and professional terms, the resistance below two hundred and ten kilograms per square centimeters are low resistance, the resistance of two hundred and ten is the boundary between structural and non-structural resistance, and above this already they are considering medium and high strength. Furthermore, other positive effects could be observed and quantified in experimentation. The bending stress experienced by civil structures is also of great importance, and the research suggests that it also heightens. It is intended to contribute to the knowledge of the Ecuadorian engineer. However, it is expected to use this work for future research. It would be grateful if the thesis is also shared for public knowledge and in the professional area, so it would be applied in the civil works of the Republic of Ecuador.
