Estudio del hormigón con fibras naturales de abacá como componente en la dosificación, con tratamiento químico : estudio del hormigón con fibras naturales de abacá al 0.75% como componente en la dosificación, con tratamiento químico NaOH.

Abstract

This text describes the influence of the use of natural fiber, in this case abaca, as an addition in the dosage of concrete to reduce the presence of cracks once the concrete has dried. Knowing that concrete has minimum elasticity characteristics, the use of materials whose main characteristic is elasticity, as is the case of abaca fiber, was used, and to make use of it, the decision was made to do it under a previous chemical treatment with 4% sodium hydroxide, which helps to eliminate organic impurities that may affect the concrete. Cylindrical specimens, beams and slabs were used to study them in compression, bending and the presence of cracks, respectively. The inclusion of abaca fiber in the concrete dosage is a function of the mass of the coarse aggregate and a minimum resistance of 210 kgf/cm2 was used to guarantee that this is a commercial concrete.
