Abstract
Waste in millions of tons is produced in the world each year and most of it is not recyclable. Furthermore,
recycling waste consumes energy and produces pollution. In addition, the accumulation of waste in suburbs and disposal of
waste is dangerous for the environment. Using waste material in concrete production is an appropriate method for
achieving two goals i.e. eliminating waste and adding positive properties in concrete. Since the green concrete industry is
expanding, it is necessary to evaluate concrete that contains waste from all aspects to determine its capability. This
research consists of analyzing the use of waste as a partial substitute for sand. Leading waste material that has been used
as substitutes is highlighted and the characteristic of the resulting concrete is evaluated in this research. Among other
findings, rubber was found to have improved fire resistance and ductility in concrete, and agricultural and Polyethylene
terephthalate (PET) wastes were successfully used in non-structural concrete, while glass helped to improve thermal
stability. In this research aggregate and sand is replaced by waste materials of Polyvinyl Chloride (PVC) and Glass to
check their effect on the mechanical properties. Lab tests were performed to analyze the flexural behavior of concrete
samples having waste material. The results show how partial replacement of sand affects the behavior of concrete and
based on that specify the conditions where it can be used. The results show that Young’s modulus, maximum bending
stress, and bending deflection varies with the percentage composition of PVC and glass. Bedding stress and bending
deflection decrease with PVC and glass composition up to 35%. Although Young’s modulus is fluctuating bending
deflection will decrease.
