Study of the effect of carbonation on concrete produced with vegetable fiber (buriti)

Abstract

This article is based on the production of concrete with vegetable fiber (buriti), emphasizing the
effect of carbonation as a form of prevention in relation to pathological causes caused in reinforced
concrete. The structuring of this project is done through the preparation of a conventional concrete
as the basis of the study to be applied as addition and / or replacement of cement in 0.5% and 1.0%
of buriti fiber. After the rupture at 28 days, these materials were exposed and the chemical indicator
of phenolphthalein was applied to be observed at 7, 28, 63, 91 and 120 of the spray.
