Through compressive strength test, the influence rule of material composition variation to the compressive strength of concrete had been studied. And the importance degree that different raw materials affected the compressive strength of concrete had been analyzed. Researches show that the importance degree that different raw materials affected the compressive strength of concrete could make a list, water cement ratio>aggregate grading> sand ratio>fly ash>blast furnace slag. The research results could be referenced for optimal design of concrete.
