Abstract: Ghana’s housing deficit is reported to have increased to about one million. Additional projection of 3.6 million houses will be required by the year 2025 to adequately accommodate the population. Similarly, the country’s road sector is yet to experience significant development. Only 18% of the road network is said to have been paved. The provision of more houses and other infrastructure such as paved roads, water and electricity supply systems requires substantial amounts of construction materials, especially concrete, which depends largely on aggregates derived from natural rock deposits in the environment.Notwithstanding, large volumes of waste materials are produced from construction and other related activities including concrete rubbles generated from demolishing of old structures, blast furnace slag from the production of steel reinforcement and many others which are eventually dumped at disposal sites at a cost. There is the need to find alternative uses for these waste materials, as this will solve two major environmental problems-reducing pollution and minimizing depletion of natural rock resources. This paper examined the potential of recycled aggregate use in Ghana and concluded that concrete rubbles from demolished concrete structures and Air Cooled Blast Furnace Slag (ACBFS), a waste product from steel manufacturing, can be recycled for concrete production to reduce environmental degradation in the country.
