Sand Replacement in Concrete Using Marble Waste

Use of marble for various decorative purposes is most common practice in construction industry. But in this process during various operations like cutting, polishing etc., the large amount of waste is generated which is hazardous to the environment. Marble waste affects the fertility of soil and causes soil pollution. Hence proper disposal is required for marble waste or it can be reused in various activities. Concrete is the mixture of cement, fine aggregate and coarse aggregate. Marble is the metamorphic rock having specific gravity is about 2.6 to 2.8 which is nearly similar to the normal aggregates. Hence the waste marble particles can be used in the concrete as partial replacement for fine aggregates. This study represents the results of compressive strength of concrete at various percentage of replacement of fine aggregates with waste marble particles. It is found that the use optimum percentage of marble waste gives the good compressive strength which in nearly about 95% of design strength. Reuse of marble waste will help to reduce the burden on environment.
