Abstract Scope |
The cement industry is a protagonist in the current economy, however, it does not act in an environmentally sustainable way, given its high CO2 emission. In this context, geopolymer composites with the use of natural fiber reinforcement appear as part of a possible solution. The geopolymer is generally made with sources of aluminosilicates and an alkaline activator solution. There are various natural fibers that can be applied as reinforcement, this work aims to elucidate the use of fibers present in the pineapple crown. The fibers were treated in a 5% solution of NaOH, after the treatment they were characterized by XRD and SEM and then added in a geopolymer matrix in the proportions of 1.6% and 3.2%, on the metakaolin mass, in addition to the production of reference samples. The mechanical properties of the composites were positively evaluated through flexural and compressive strength tests. |
