Abstract

Barru Regency is a coastal area with abundant potential for Wahede beach sand, which can be used to make economical concrete. This research aims to determine the compressive and tensile strength values of concrete as well as the optimal percentage of the beach sand mixture. The research was carried out at the Structure and Materials Laboratory of the Muhammadiyah University of Parepare, with a planned compressive strength of 20 MPa.The results of research on normal concrete compressive strength at 7 days were 12.27 MPa, 14 days 13.97 MPa, and 28 days 20.29 MPa. Variation: 25%; compressive strength: 7 days 13.58 MPa, 14 days 15.85 MPa, and 28 days 21.89 MPa. Variation 50%, compressive strength 7 days 14.34 MPa, 14 days 18.68 MPa, and 28 days 22.08 MPa. 100% variation, compressive strength: 7 days 14.72 MPa, 14 days 19.34 MPa, and 28 days 25.48 MPa. The split tensile strength of concrete decreases with an increasing percentage of beach sand: normal 28-day concrete 7,852 MPa, 25% variation 6,222 MPa, 50% variation 6,963 MPa, and 100% variation 8,000 MPa

Abstract

The problem of plastic waste that needs to be handled and managed optimally can cause environmental damage. This study aims to test the compressive strength and water absorption value of paving blocks made of plastic which are designed using a mixed variation of V50-50 (50% sand, 50% plastic), V25-75 (25% sand, 75% plastic) and V0-100 (0% sand, 100% plastic) of the total proportion of the paving blocks mix. The method is carried out by melting PP (Polypropylene) mineral glass plastic, mixing with sand based on variations, printing according to the size of the paving block, and using as a test sample in the form of a dice. The average compressive strength test results show that the model with code V25-75 has a relatively higher compressive strength value than V50-50 and V0-100. The average compressive strength value of the sample with code V25-75 is 11.53 MPa, followed by code V50-50 of 9.63 MPa, and the lowest is coded V0-100 of 3.70 MPa. The compressive strength value is influenced by the optimal percentage between sand and plastic; plastic serves as a binder for sand in a mixture of paving blocks. The rate of water absorption value will continue to decrease along with the addition of plastic waste in the paving block mixture; V50-50 is 1.44, V25-75 is 0.88, and V0-100 is 0.16. This research is expected to be applied by the community to make paving block products to reduce the amount of plastic waste globally.
