Abstract: The growing population has increased the demand for residential and commercial buildings. As a result of demolition of these buildings, lot of construction waste is generated. Most of these waste are non-biodegradable. When put into landfills, these waste pollute the land and harm the environment. Therefore, need of recycling these materials and using them is necessary. Concrete aggregates from demolished buildings can be reused to make concrete. However, its strength is immensely affected due to cement paste and mortar attached to it. Experimental research was carried out to determine how strengths of concrete made of natural aggregate, rejected concrete batch aggregate, aggregate from 8 years and 16 years old demolished buildings vary and also the feasibility of each. Different ratios of each type of recycled aggregates were taken along with the natural aggregates to determine how strength varies with change in ratio.
