The Effect Research Of Mineral Mixture To The Compatibility Of Cement And Admixture

In 21 century,the path of concrete is green concrete, that is how to use each mineral admixture to improve the high performance and unpollution of concrete. By research the effect of mineral mixture on cement and admixture,we can improve it's utility in cement concrete.in this article we use the slag and fly ash as research object.we study the effect of the mineral 's dosage on the compability of different fineness cement and admixture,the effect of mineral fineness to the compatibility of cement and admixture.wo also research the effect of mineral to different cement and admixture in chongqing.by the study,we continue changing the character of mineral to improve it's effect to compatibility.slag and fly ash mix each other can have better character to the compatibility of cement and admixture.changing slag by admixture and gypsm also can improve it's compatibility to cement and admixture. By research these ,wocan know: 1) in different fineness cement, the dosage of mineral admixture improve the fluidity of cement mortar.when the dosage reach 50%, the effect of mineral on fluidity can be better than the changing fineness of cement .2)to different fineness and dosage mineral,the improve of mineral can improve the compatibility . 3)when changing the purface of slag,can improve the character of cement, be better to the compatibility .4) because the different component,the effect to cement and admixture is different. When they mix each other ,in one rate,they can compensate it's defect and improve the compability.5) in the concrete with slag or fly ash, the changing of addition has more affection in slag's concrete than fly ash.
