ABSTRACT:
A material that is a mixture of polystyrene beads, type III cement, an acrylic latex bond and water. The mixed material is placed in a mold and compressed prior to curing to increase the density, to provide a uniform surface finish and to increase the strength of the end product. The insulating value of the end product is substantially the same as a product formed without compressing the material.
