ABSTRACT:
A method and apparatus is provided for the manufacture of concrete products in which a mixture comprised of cement, aggregate, a vinyl acetate-dibutyl maleate copolymer and an amount of water sufficient to make a relatively dry mixture is initially compressed into the desired configuration. This compressed-shaped article is then cured in a chamber charged with carbon dioxide gas to provide a fully cured concrete product having excellent physical properties. The method and apparatus of this invention is especially useful in the manufacture of terrazzo panels and the like.
