Cast stone

Jump to navigation Jump to search


A precast building stone prepared from several formulations that harden to a rocklike solid. Examples of some cast stone binders are: Clay (Coade's stone), Plaster (Protean stone), Water glass (Siliceous Concrete Stone), Oxychloride cement (casting stone), Keene's cement (marezzo marble); [[Epoxy|epoxy], and Portland cement (Frear stone, Victoria stone, Benedict stone). Cast stones were used extensively in the late nineteenth and early twentieth centuries. They often incorporated fine and coarse aggregates for texture along with pigments or dyes to imitate coloring and veining of natural stones. Cast stones were produced in many sizes and shapes, often with intricate patterns and tracery.
