ABSTRACT

Concrete, as a constructive material, has been used in construction industry for about two centuries. Approximately, the whole bulk of the concrete is used in one year is more than one ton apiece. Therefore, doing research about using modern technologies in production concrete is of great importance. Furthermore, one of the most critical problems of the world has been related to remove the wastage and reusing of it. Reducing the necessary amount of Portland cement without reducing the performance of concrete is significant for big projects that require a large amount of cement. Waste material recycling through using in concrete manufacturing not only provides a promising resource to produce a high quality concrete, but also helps to properly encounter the problem of waste disposal.

The present experimental study deal with the investigation of possibility of using Marble Waste Aggregate in concrete as coarse aggregate replacement upto 50% with 10% fixed proportion along with nano silica as cement replacement of 0, 4 and  8% respectively of M20 & M30 grade of concrete  Besides, all other parameters are constant. Finally the slump value, compressive strength of the concrete for the samples were calculated. The findings revealed that generally using Marble Waste Aggregate lead to enhancing the properties of concrete.
