Mortar cube (MC) studies were performed to assess the feasibility of QD and USS as fine aggregate in concrete. There are no specified codes for performing the feasibility studies on QD and USS binding properties, hence the tests were conducted as per IS 650:1981 [29] and IS 10080:1982 [30].The IS 650:1981 code suggests the determination of cement strength by …
