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. Furthermore, Portland cement clinker production consumes large amounts of energy and has a notable environmental impact, which involves massive quarrying for raw materials. 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. A large bulk of ceramic tiles change into wastage, these waste materials are not reusable and recyclable due to their physical and chemical structure. Given the high amount of concrete production and the possibility of wastage materials in them, using ceramic wastage could be an effective measure in maintaining the environment and improving the properties of concrete. The present experimental study deal with the investigation of possibility of using plastic in concrete as fine aggregate replacement upto 25% with 5% 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.
