Abstract
A method and apparatus is provided for the manufacture of products of concrete or like construction, in which a mixture of calcareous cementitious binder substance, such as cement, an aggregate, a vinyl acetate-dibutyl maleate copolymer, and an amount of water sufficient to make a relatively dry mix is compressed into the desired configuration in a mold, and with the mixture being exposed to carbon dioxide gas in the mold, prior to the compression taking place, such that the carbon dioxide gas reacts with the ingredients to provide a hardened product in an accelerated state of cure having excellent physical properties.
