Compuesto de cemento reforzado con fibras de totora.

Abstract

In composite materials, one of drawbacks is low adhesion between reinforcement and matrix. For the treatment of this connection, different physical or chemical treatments are carried out that produce structural changes on the surface of the fiber and improve properties of fiber. compound. In this same order and direction, high alkalinity of Portland cement paste inside a compound protected against steel fibers from corrosion, but it affects other types of fibers that deteriorate with the passage of time, such is the case of glass and natural fibers. In natural fibers, a degradation process occurs due to the chemical attack that with time produces alkalized water that contains cement (Saraz, Aristizabal and Mejía, 2007). Therefore, three paraffin treatments are used, a chemical solution, which helps to improve the fiber within the compound. Finally, after of analysis process, the results obtained from different tests carried out, it was determined that paraffin treatment is an appropriate process.
