Pengaruh Penambahan Zeolit Alam Pahae dan Ampas Teh sebagai Fiiler dengan Resin Polyester Sebagai Perekat terhadap Karakteristik Beton Polimer

Abstract

Research has been conducted on the effect of adding natural Pahae zeolite and tea leaves as fillers on the characteristics of polymer concrete and polyester resin as adhesives. The sample preparation began with zeolite being sieved using a 74 μm sieve, washed three times with distilled water, and dried at a temperature of 150°C for 2 hours. XRF characterization to determine the elemental and compound content in zeolite. Tea leaves were dried at 60°C for 2 hours and sieved using a 149 μm sieve. Sand was sieved with a 149 μm sieve. The composition used: sand, zeolite, tea waste with variations of polyester resin 15 g, 20 g, and 25 g. The mixed materials were molded using a hot press at a temperature of 170°C for 30 minutes. After printing, characterization of physical, mechanical, as well as morphology and elemental properties was conducted using SEM-EDX. The research results indicate that polymer concrete with the addition of tea waste and Pahae natural zeolite filler can improve the physical properties of polymer concrete. The addition of polyester resin in polymer concrete results in decreased mechanical properties. The morphological analysis results on SEM-EDX of polymer concrete show the distribution of Si and Al from zeolite is almost evenly spread across the entire surface of the polymer concrete.
