Utilizing waste and recycled materials in fly ash fiber-reinforced mortar

Abstract

       This experimental investigation was conducted to determine the effect of fiber type and mixing proportion on the strength and durability of fiber-reinforced mortar with fly ash. The compressive strength was not significantly affected by sand-binder ratio, but flexural strength increased as sand-binder ratio increased. Increasing the volume of fly ash resulted in a decrease in compressive and flexural strength, flexural toughness, and air permeability, but this result may be attributed to the slow curing speed of fly ash. Polypropylene and recycled fiber mortars exhibited similar behavior. [This abstract is not included in the PDF]
