| Abstract: | By analyzing the chemical composition of high calcium fly ash and fly ash mixture, the mechanism in strength was expounded in this paper.Based on the method in Test Methods of Materials Stabilized with Inorganic Binders for Highway Engineering, the technical performances of the mixture of high calcium fly ash and fly ash in highway application were studied by systemic experiments. Which includes the strength, modulus and water stability. And the influence factors of the mixture strength were analyzed, too. The results show that the mixture has higher strength and modulus, good water stability. The technical performances of high calcium fly ash and fly ash mixture conform to the current specification, so that can be used as sub-base course or base course. |
