Description
A very hard, fast-setting gypsum plaster developed by Richard W. Keene in England about 1840. Keene's cement is made by heating Plaster of Paris to form Anhydrite then soaking it in an Aluminum sulfate solution to reform the hemihydrate calcium sulfate. The alum acts as an accelerator which provide nuclei for the rapid, fine-grain solidification. Keene's cement forms a hard finish plaster that has been used in frescos as well as for the repair and modeling of sculptures. An imitation marble, marezzo, is also made with Keene's cement.
