Over the years, advancement in the construction industry and the need for change and improvement towards new structures have led to increase in the use of construction materials and generation of construction and demolition wastes (CDW). These construction wastes are aesthetically displeasing and not of good environmental impact. Its presence in the environment also occupies space. This study reviewed researches carried out independently by different researchers to establish the recycling of

This puts into consideration the integrity of new structures built from using these concrete wastes; hence researching into its impact on certain properties such as workability, compressive strength, water absorption and more. The line drawn from the distinct works established the possibility of recycling concrete wastes for further use in construction purposes with retention of structural integrity. The results from two research works compared established 25% to 30% optimum replacement level of recycled concrete with satisfactory structural properties.
