Therefore, the use of cement fly ash gravel (CFG) instead of DCM columns has been introduced. The objective of this paper is to present an experimental investigation of the properties of CFG. Gravels with sizes of 4.76 to 12.70 mm were mixed with ordinary Portland cement (OPC) Type 1 and fly ash (FA) to create CFG materials.
