摘　　要：A research project wus conducted to manufacture eco-cement for sustainable development using cement kiln dust（ CKD ） and granular blast furnace slag（ GBFS ）. In the project, the burning process and minerul compositions of CKD dinker were investigated. Different minerulizers such as CaSO4 and CaF2 , sulfur and alkali corttent were coasidered. The strength of CKD and GBFS eco-cement were evaluated. The results indicate the CKD clinker can not only form ordinary cement clinker minerals such as C3 S, C2 S and C4 AF , but also form such high-reuctive minerals as C4 A3 S and C. A7 · CaF2 . The CKD and GBFS eco-cement will have the similar strength to the Portland cement grade 32.5 when blend proportion is properly applied.A research project wus conducted to manufacture eco-cement for sustainable development using cement kiln dust（ CKD ） and granular blast furnace slag（ GBFS ）.
