The attention of the world towards sustainable development is one of the major concerns from the past few years. This may be due to use of natural resources in bulk quantity in construction sector or any other industrial sector. This act of using huge volume of natural aggregates in construction industry leads to the shortage of natural aggregate in construction process. The latest trend in construction industry is to use alternate materials which can be best substitute of natural aggregates so that there is no compromise in terms of strength and durability considerations of structure. Reusing waste materials as an alternative to natural aggregates can help in reducing environmental problems, pollution, waste disposal and global warming. From the last few years, it has been found that the waste generated from demolition of construction site and old structures is increasing at more rapidly. Thus, reusing and recycling these wastes may reduce the usage of natural aggregates and thus contribute in reducing environmental hazards. Marble powder creates environmental problems but due to presence of high oxide calcium content, which is cementing property, marble can be used as in the partial replacement of cement in cement sand mixAs nowadays, marble is widely used in structures which increase the amount of waste that obtained from it. As marble powder is the waste product which is obtained during the process of sawing and shaping of marble by parent marble rock, contains heavy metals which makes the water unfit for use.. It is also useful because marble waste is a by-product of marble production and also creates environmental pollution in large scale. Therefore, it could be possible to prevent the environmental pollutionIn this research work, the effects of using waste marble powder (WMP) as a partial replacement of cement and sand on the mechanical properties of the concrete have been investigated. For this purpose seven different series of concrete-mixtures were prepared by partially replacing cement, sand with WMP at proportions of 0, 10 and 15% by weight separately and in combined form. In order to determine the effect of the WMP on the compressive strength, split tensile strength and flexural strength, strengths of the samples were recorded at the curing ages of 7 and 28 days. Finally, all of the data were compared with each other & it was observed that the addition of WMP such that would partially replace the sand and cement separately at particular proportions has displayed an enhancing effect on the mechanical properties of concrete mix.
