Abstract: This state of art review represents the development in the field of utilization of used foundry sand in cementitious concrete. The paper reviews the utilization of foundry sand as the concrete constituent and the noticeable and important findings from the experimental works of various researchers. The historical development is also discussed as a part of introduction in the review. After a careful study of large number of research papers on the topic it was felt by the authors to integrate all the important results for streamlining the potential of this area of research. The paper summarizes conclusions of experiments conducted for the properties like strength and durability. It was observed the results have shown positive changes and improvement in strength and durability properties of the conventional cementitious concrete due to the addition or replacement of fine sand with used foundry sand in different proportions. However in couple of cases such addition has reported reduction in the values of properties. From the review of past research works it could be concluded that utilizing the used foundry sand holds a great potential towards the development of environment friendly and sustainable cementitious concretes.
