COLOR CEMENT COMPOSITION FOR ROADWAY PAVEMENT AND MANUFACTURING METHOD THEREOF

摘要

A method for preparing colored cement composition for roadway is provided to produce colored concrete having excellent visibility without discoloration caused by UV and chemical substances using inorganic iron oxide with higher degree of particle size than that of cement particles. A colored cement composition for roadway comprises 30-80wt% of portland cement, 5-60wt% of blast furnace slag, 1-25wt% of fly ash or silica fume, 1-7wt% of II type anhydrous gypsum and 2-10wt% of inorganic pigment. The inorganic pigment is selected from the group consisting of Fe2O3, PbCrO4, PbMoO4, Cd(SSe), Pb3O4, FeOOH, PbCrO4, chrome green, navy blue, deep blue, Fe2O3, carbon black and TiO2.
