钢渣彩色水泥熟料低温烧成及其性能研究

水泥窑中直接烧成的彩色熟料水泥具有成本低、色泽鲜艳、色彩稳定性好等特点.本文着重探讨了在能源紧张情况下,利用氟、硫复合矿化剂低温烧成钢渣彩色水泥熟料的可能性.通过 X 射线衍射、扫描电镜观察和红外光谱等近代测试分析技术及化学分析、常规物理力学试验方法对用水泥工业性优质原料配料和掺电炉还原钢渣配料高低温烧成彩色熟料的矿物组成、色彩情况、物理力学性能及其特性进行了分析研究.

STUDY ON THE LOW TEMPERATURE CALCINATION AND THE BEHAVIOUR OF STEEL SLAG COLOUR CLINKER CEMENT

The colourcd clinker cement which fired directly from kiln has the advantages of low cost,bright colour and good colour durability.This paper studies the possibility of using calcium flouridc and gypsum combined mineralizer to calcine the col-outed clindcr cement at low temperature.Different methods such as X-ray diffraction ana ysis,scanning electron microscopy,infrared spectra analysis,combined water content chemical asysis,compressive strength test and so on arc used to study the clinder minerals,the colour,the physical and mechanics properties and behaviour of the coloured clinker cement which made both with high quality raw materials and with electric furnace reduced slag additive.
