Abstract
The research discovers the effects of adding roselle fibers in high-strength concrete. Due to increasing environmental concerns, researchers replacing synthetic fibers with natural fibers. Insufficient quantity of materials presence leads to a way to find substitute materials. This research work discusses the mechanical and durability performance of roselle fibers reinforced high strength concrete. Silica fume -10% and metakaolin -5% were added as cementitious mixtures in both Concrete specimens. The experimental work was carried out with various fiber percentages from 0 to 3%. The results show that the optimum quantity of fiber requirement is 2%. Comparison was made between FRC (Fiber reinforced Concrete) specimens and conventional concrete specimens. The comparison shows concrete with fibers exhibits higher strength than conventional concrete. Due to the utilization of Silica fume and metakaolin, the cement requirement is reduced and with this, the CO2 emission is highly reduced. There was an increase in compressive strength, split tensile strength, and flexural strength by 23%, 10.04%, and 10.72% respectively with 2% roselle fiber. Durability test results suggest that these values are acceptable for constructing durable structures. Roselle fibers usage in concrete has vast applications in the construction sectors. The scientific name for roselle fibers is Hibiscus sabdariffa and it belongs to the Malvacea family. Roselle fiber’s are widely used in the textile industry. Roselle fibers presence shows enhanced performance than plain specimens. It is recommended that roselle fiber reinforced concrete would be feasible for durable concrete structures including high-rise buildings and multi-storied buildings and it makes a way to create an eco-friendly environment.
期刊介绍：
The journal Silicon is intended to serve all those involved in studying the role of silicon as an enabling element in materials science. There are no restrictions on disciplinary boundaries provided the focus is on silicon-based materials or adds significantly to the understanding of such materials. Accordingly, such contributions are welcome in the areas of inorganic and organic chemistry, physics, biology, engineering, nanoscience, environmental science, electronics and optoelectronics, and modeling and theory. Relevant silicon-based materials include, but are not limited to, semiconductors, polymers, composites, ceramics, glasses, coatings, resins, composites, small molecules, and thin films.
