Construction waste recycling in sustainable engineering infrastructural development

Nigeria is a developing Country with a large population and land area. In recent years there has been an increase in the number of construction industries and concrete is the main construction material for most of the structures that are being built. This paper considers the option of recycling construction wastes. This approach is environmental friendly and will reduce cost of construction. To improve the quality of recycled aggregate, the water cement ratio should be decreased or alternatively, fly-ash could be used as an additional cementitious material.
