Abstract

The invention relates to a white or colored cement-based composite material used for art wares. The cement-based composite material is prepared by compounding 21.5-55.8% by weight of white cement, 5-45.9% by weight of metakaolin, 16.5-47.7% by weight of quartz sand, 0.8-2% of a water reducer, less than 0.1-4.5% by weight of fiber, less than 0.1-10% by weight of pigments, and water, wherein the water-glue ratio is 0.22-0.4, and the water-glue ratio is the ratio of the weight of the water to the sum of the weight of the white silicate cement and the weight of the metakaolin. The cement-based composite material has characteristics of high performance, diverse colors and diverse varieties, and can achieve long artistic effects.
