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.
