ABSTRACT
It is indicated that most of the contributors to CO2 emissions in the air come from industrial cement. One of the materials that can be used as a substitute for cement in concrete mixes namely fly ash, but the use of fly ash can increase drying shrinkage which reduces the initial strength and mechanical properties of concrete. This study aims to examine the compressive strength, split tensile strength, and strong flexible concrete mixed with fly ash with added pineapple leaf fiber at 14, 28, and 56 days of age. The composition of fly ash as a substitute for cement is 10%. Pineapple leaf fiber added to the concrete mixture is 0.0%, 0.3% and 0.6. The test results show that the compressive strength, splitting tensile strength, and flexural strength of concrete increase with age. The compressive strength test showed the highest compressive strength value in concrete with 10% fly ash and 0.3% addition of pineapple leaf fiber (PCC-FA-SN0.3), namely 29.91 MPa at 56 days old, an increase of 23.33% against concrete PCC-FA-SN0,0. The split tensile strength test showed that the split tensile strength of PCC-FA-SN0.3 concrete had the highest split tensile strength of 2.29 MPa at 56 days of age, an increase of 15.46% compared to PCC-FA-SN0.0 concrete. The flexural strength test showed the highest yield on PCC-FA-SN0.3 concrete of 4.71 MPa at 56 days of age, an increase of 13.46% on PCC-FA-SN0.0 concrete. Based on these test results, fly ash mixed concrete with the addition of pineapple leaf fiber shows good potential to be used as an innovation in the field of concrete technology because it can improve the mechanical properties of concrete.
