Análisis de las propiedades mecánicas del concreto al añadir fibras de acero en forma triangular

Abstract

Because the mechanical properties of concrete are often insufficient and do not meet the requirements imposed on it, it has been decided to experiment by modifying the shape of the steel fibers to a triangular shape and implementing them as reinforcement to the concrete mixture, given that it is not desired to study the effects of implementing different dosages in the mixture but only as the properties of the concrete change when changing the shape of the fiber, the dosage suggested by the manufacturer will be taken.

By improving the mechanical properties of concrete by adding steel fibers, costs and labor in different constructions are reduced. Mainly the stone material will be acquired from the Agremet plant and work with the Holcim cement.

The concrete mix will be carried out at the Santo Tomas University facilities, the formwork process of the joists and cylinders will be started for later testing at 7, 14 and 28 days of curing, taking the samples to an independent laboratory ending with the resistance tests of the samples for later data collection and result analysis.

In this investigation it is desired to verify that the samples reinforced with steel fibers in a triangular shape are more efficient and demonstrate a better result than the samples reinforced with conventional steel fibers. According to the results analysis, it was shown that samples containing triangular shaped steel fibers greatly improve the compressive and flexural strength of concrete.

It is feasible to construct elements such as slabs and to use concrete reinforced with triangular fibers in elements where there is a high risk of cracking and in constructions where time is limited since this reduces construction time compared to traditional reinforcement.
