The aim is to utilize waste synthetic marble made of marble and study the effect of these variables marble grain size, amount of catalyst and heavy marble grain on the compressive strength, the wear and water absorption. Materials - the materials used, among others; a. Marble waste, which is obtained from the village Besole, Tulungagung, b. Synthetic Resin (R-154) already in accelerasi. C). Catalyst acid (HCl) with pH ± 4.5. Tools - tools used are a). Machine press with a maximum capacity of 60 tons that have hit the maximum scale division 500 kg.b). Pengaus machine or abrasive objects that can rub try with 3.33 kg load and speed of 49 meters per minute wear. C). Matter. D). Pestle., e). Measuring cup. F). Analytical Balance. Research variables are specified condition that is a). Temperature = 30 o C, b). Resin volume = 40 ml; c). The samples sizes are: Diameter = 5.08 cm, Height = 2 cm; (surface area = 40.5161 cm2); d). Time = 4 hours The treatments are carried out is a). Size Pellets Marble = (10, 16, 20, 35, 48) mesh, b). Catalyst amount = (0.2; 0.4; 0.6, 0.8; 1.0) ml; c). Marble Grain weight = (50, 55, 60; 65; 70) grams.
