Reinforced concrete mixture using abaca fiber

Abstract

Abstract This research study discusses the reinforcement of concrete mix design using abaca fiber. The process of mixing the abaca fibrous concrete used in this mixing is the dry mixing method. The addition of abaca fiber to concrete mixture was done with abaca fiber composition with fiber variation: 0%; 0.15%; 0.20%; 0,25% and variation of fiber length: 25 mm; 37.5 mm; 50 mm. The specimens of cylindrical material (100mmx200mm) and beam (100mmx100mmx400mm), are tested after the test object reaches the age of 28 days in the Universal Testing Machine (UTM) and are evaluated through the ASTM standard in compressive strength test, splitting tensile strength and flexural strength. The addition of fibers significantly affects the physical properties of the concrete, when the fiber increases the slump value will be smaller so the mixture becomes more difficult to mix. The results obtained by the abaca fiber concrete mixture for the composition (0.15%) and the ideal fiber length (50 mm) by providing an optimum value increase in the compression test of 12.61%, 72.64% tensile test, 98.98% flexural test of the normal concrete mixture.
