Abstract

Research on alternative materials primarily from waste have been additional material at area manufacture of building materials , especially concreteroof tile [ 1 ] - [ 17 ] . This research will expand utilization of marble waste vBulletin East Java region of Indonesia in the manufacture of concrete roof tiles by combining the use of sand and waste marble powder as a substitute for riversand and portland cement .. This research creates material innovation product of environmentally friendly with relatively low prices without compromising quality. The purpose of research is to find the composition of the mixed-use waste marble tile that produces the most optimal strength . Experimental method used in this study to test the basic material and test physical and mechanical properties of concrete roof tiles ( bending loads , water absorption and resistance to water seepage ) in accordance with ISO 0096 : 2007 with eight variations in material composition . Concrete tile with marble waste produces a lighter weight 3.6 % - 12.3 % . Replacement PC with marble powder by 20 % qualify flexural strength , water absorption ( no more than 10 % ) and there is no seepage within 20 hours ± 5 minutes . Composition tile marble concrete using waste as a substitute for river sand PC and a decent and qualified SNI 0096:2007 is a composition of 0.8 PC : 0.2 SL : 1 Ps : 2 PSL and composition 0.8 PC : 0.2 SL : 3 PSL . While most optimum is 0.8 composition PC : 0.2 SL : 1 Ps : 2 PSL . which produces Flexture1141 N.
