Pembuatan dan Karakterisasi Beton Polimer Berbasis Limbah Pulp Dregs Sebagai Agregat dan Resin Epoksi sebagai Perekat

Abstract

A research has been done to make a polymer concrete made from a mixture of sand, pulp waste dregs, epoxy resin and thinner. This research was conducted to determine the best mix of sand and waste pulp dregs as a free variable and the epoxy resin and thinner as a remains variable. The properties of polymer concrete were analyzed, namely the physical properties include density, porosity and water absorption, mechanical properties include impact strength and flexural strength, as well as analysis of the microstructure of the polymer concrete is SEM-EDX. The best result was obtained in a mixture of sand and waste pulp Dregs in the ratio (65:35) g, and the addition of 30 g of epoxy resin and 15 g thinner. Values obtained density of 1.80 g/cm3, porosity 10.36%, water absorption 5.74%, impact strength 2,705 kJ/m2, and flexural strength 26.82 MPa.
