应用XRD分析水泥窑灰矿渣型生态水泥水化过程的研究

选用4种不同类型的水泥窑灰（CKD），利用XRF分析其化学成分，并将其分别与粒化高炉矿渣粉（GBFS）制成4种生态水泥。然后根据CKD-GBFS生态水泥净浆的水化产物的XRD图谱与各龄期的胶砂抗压强度研究其水化过程。结果表明：高碱度的CKD能促进水化，适量的fCaO能加快后期水化，而未反应的Ca（OH）2会降低后期抗压强度，K2Ca（SO4）2的产生会延缓水化进程。

Study、on hydration process of CKD-GBFS Eco-cement by XRD

Four different types of cement kiln dust(CKD), compositions of which were analyzed by XRF, were selected to make four types of Eco-cement with granulated blast furnace slag(GBFS) to analyze hydration progress of eco-cement with compressive strength of mortar by XRD. The results showed that high alkalinity of CKD could accelerate hydration, and appropriate fCaO content of CKD could hasten the rate of hydration in later age, and unreacted Ca(OH)2 could decrease later compressive strength as well as the creation of syngenite retarded hydration.
