To achieve this, concrete samples were prepared according to established methods, and the samples were molded. The percentages of magnesium oxide nanomaterials varied from 0% to 2% of the cement weight, while the percentage of polypropylene fibers ranged from 0% to 1.4% of the cement weight. The results indicate that the maximum compressive strength is achieved on average with 0.5% magnesium oxide nanomaterials and 0.8% polypropylene fibers. This trend is also observed in the splitting tensile strength and flexural strength. The water absorption of 28-day concrete without fibers and magnesium oxide nanomaterials is approximately 4.3%, which decreases to 3.1% as the amount of nanomaterial increases to 2% of the cement weight. polypropylene fibers mechanical behavior concrete nano magnesium oxide Full Text Additional Declarations No competing interests reported.
