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 mixture is initially compressed into the desired configuration. This compressed shaped article is then subjected to an accelerated curing process in a chamber that is charged with carbon dioxide gas to provide a hardened product in an accelerated cure state having excellent physical properties, although the apparatus may be used, if desired, to provide only a desired amount of curing, as the circumstances may dictate. The method and apparatus of this invention is especially useful in the manufacture of panels, such as of terrazzo and terrazzo-like types and building panel elements of both load-bearing and non load-bearing types, concrete blocks, ceramic products, cinder blocks, bricks, adobe constructions, concrete pipe, drainage tile, silo block or staves, pre-cast tile, filler base, load bearing structures, non-load bearing or curtain wall structures, and pre-stressed products, among othe…
