Development of A New Method for Optimum Mix Design of Roller Compacted Concrete



In this paper, an optimum mix design method is presented for Roller-Compacted Concrete (RCC). It is shown that the total cost of RCC designed according to ACI207 requirements can be decreased so that its strength is equal to the same strength resulting from traditional mix design. As a practical example, optimum mix design of a RCC sample with a cylinder strength of 140 Kg/cm2 that is approximately equal to the strength of experimental specimens is performed through the new method. The results are compared with those obtained from traditional mix design method and it is shown that the results are improved.
