RESEARCH ON REUSING WASTE PLASTIC FLAKES OF SCRAP PLASTIC GRINDING FACILITIES TO PRODUCE CONCRETE BRICKS

Abstract

This study focuses on assessing the possibility of using plastic flakes from scrap plastic grinding facilities of Trieu Khuc plastic recycling village to produce concrete bricks. The study also tests the addition of denatured aluminum slag into brick to minimize the amount of solid waste that would be buried. These brick samples are composed of dust mites, cement, waste plastic flakes and/or denatured aluminum slag. The test results of concrete brick samples show that the percentage of waste plastic chips, denatured aluminum slag can reach 25-35% of the mixing volume. The compressive strength of the test samples can reach the grade of M35 bricks, even close to the grade of M100 bricks. The addition of denatured aluminum slag requires further research as well as additional consideration of adding a binding additive to increase the compressive strength of the product brick.
