Abstract

Developments in the structural field are currently progressing so rapidly that concrete is one of the choices as the main structural material in development. Self compacting concrete (SCC) is a concrete mixture consisting of water, cement, stone, sand and superplasticizer so that SCC has a high level of fluidity, is able to compact itself and flow through the gaps of reinforcement without the help of a vibrator. SCC can be flexure or deformation and cracks due to strains that arise due to external loads so that SCC will be reinforced with macro and micro polypropylene (PP) synthetic fibers with a percentage of 0%; 0.75%; 1% and 1.25%. This study was conducted to determine the flexural strength and collapse patterns that occur in SCC reinforced with macro and micro PP synthetic fibers. The flexural strength test was conducted on the 28th day with 21 beams of dimension 100 x 100 x 350 mm. The collapse pattern was analyzed by measuring the length, width and number of cracks after the test. The test results for normal SCC were 5.174 Mpa, SCC with the addition of PP macro fiber were 5.753; 6.438; 6.874 MPa and SCC with the addition of PP micro fiber were 5.753; 6.438; 6.874 Mpa. The flexural strength increased as the percentage of PP macro and micro fibers increased. The collapse pattern of PP macro fiber SCC was able to reduce the length, width and number of cracks. The PP microfiber SCC was able to reduce the width and number of cracks but the length of the cracks were connected on each side of the beam due to the PP microfiber binding properties of the SCC mixture.
