The present invention refers to a process for the production of artificial granite, using high alumina cement, quartz sand crushed stones, inorganic pigment powder, propanetriol, and water as the main raw materials. The mixture of the said raw materials with different ratio are poured into mould in three steps adopting compound structure of coloured slurry layer, pigment layer, and reinforced layer, then put into water for curing after vibration. The granite thus made is similar to the natural granite in figure with physical specifications superior to the current prevalent polyester type artificial granite; thus it is a new decorative building material.
