Cast stone
（重定向自Synthetic stone）
Cast stone is a concrete masonry product simulating natural-cut stone and is used in architectural applications. Cast stone is used for architectural features: trim, or ornament; facing buildings or other structures; and for garden ornaments. Cast stone can be made from white and/or grey cements, manufactured or natural sands, crushed stone or natural gravels, and colored with mineral coloring pigments. Cast stone may replace natural-cut limestone, brownstone, sandstone, bluestone, granite, slate, coral rock, travertine, and other natural building stones.
