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. Keywords : marble waste , bending loads , water absorption , concrete rooftile I. INTRODUCTION Technology expasion at area of construction has rapidly depeloped. Some studies construction technology continues to be developed with the aim to generate appropriate construction technology , easy to work , as well as efficient in financing . Research of alternative materials is something that is often used as the object of study, because the material was found appropriate alternative, it will be an effect on cost efficiency . Alternative materials, especially industrial waste materials are still many who have not utilized optimally . The waste material would be a waste if a certain amount is not handled properly can even cause environmental disturbance . Some of these alternative materials research has been carried out , among others, is the replacement of river sand with sand marble / onyx on concrete tile [1] on the composition 1 PC : 1 Ps : 2 PSO concrete tile bending loads increased by 327.86 N ( 29.26 % ) of normal concrete tile . Replacement of sand with sand on the paving block onyx [2] at 1 PC composition : 6 PSO paving block compressive strength increased by 147.72 kg/cm2 ( 64.05 % ) , compared with the compressive strength of paving block composition 1 PC : 6 Ps ( 0 % sand onyx ) . Apart from a few studies that have been conducted primarily on the use of marble and onyx sand substitute for river sand as an ingredient in the manufacture of building materials , there are also studies that utilize waste white marble floured redness results from marble stones are processed into a variety of crafts . This powder when mixed with water will harden and serve as a binder ( Sri Utami , 2010) . The results of marble waste as a substitute for portland cement paving stone on the results of 20 % replacement of portland cement with marble waste powder with composition 0.8 PC : 0.2 Lm : 5Ps yield strength Kg/cm2 159.43 paving stone composition compared with 1 PC : 0 Lm : 5ps 156.23 kg/cm2 which generate power . From the results of these studies apparently marble waste material potential to be developed as an alternative material for the manufacture of building materials can be used in addition to proven as a substitute material such as sand and cement , are also able to improve the quality of building materials . The other reason is the problem of the availability of materials . Availability is pretty much a waste marble because marble quarry resources found on several areas in Indonesia and has many uses and has been used by the people of Indonesia as a raw material in industry or handicraft marble stone marble . That occurred during this marble waste generated from the treatment process is not used and thrown away by local marble manufacturers , causing waste less useful . One of the marble waste control efforts is by making use of waste ( residue ) as building materials such as concrete tile , and brick paving . This study is a follow-up that aims to optimize the utilization of waste marble as a material substitute roles river sand with sand marble or reduce the use of Portland cement with marble powder . It also is an effort to make the production of building materials innovation by utilizing the existing waste and make environmentally friendly building materials with relatively low prices without compromising quality. The purpose of this study was to determine the effect of replacement of marble sand with river sand replacement PC with marble powder on the physical properties of concrete tile covering seepage water absorption and water resistance , as well as the mechanical properties of the concrete tile bending loads . Another aim was to determine the composition of a mixture of concrete tile with marble wastes as substitutes for PC and river sands that produce the most optimal strength .
