Abstract Scope |
Portland cement is widely used in civil construction due to various convenient properties, however, in its production processes a large volume of polluting gases is dispersed in the atmosphere, harming the environment. Composites of geopolymer matrices reinforced with natural fibers emerge as potential mitigators of the use of conventional cement, reducing the emission of pollutants. Pineapple crowns are a residue generated on a large scale in fruit producing places, making their use in composites possibly viable. This work carried out a chemical treatment of the fibers of the pineapple crown leaves in a 5% NaOH solution to study the properties of a geopolymeric mortar in the fresh state, with the addition of 2% and 4% of the reinforcing elements, on the mass of metakaolin. Consistency tests, incorporated air content, density in the fresh state and viscosity were carried out, which verified a good workability of the mortars. |
