This experiment was conducted to investigate the engineering properties of fly ash cement concrete for rigid\ud pavement construction. Results have shown that 30% of fly ash and 70% of cement has a superior performance.\ud In addition, the use of fly ash would result in reduction of the cost of cement which is usually expensive in all\ud construction materials. High strength of concrete can be made by this and the further integration of admixture or\ud alternate adds to improve the properties of concrete. Test result of specimens indicates that the workability and\ud strength chacteristcs are changed due to incorporation with fly ash. Slump test having an appropriate workable\ud mix of a concrete, gave sufficient compressive strength and fl...
