Title: Improvements in the manufacture of reconstructed stone
IPC: C04B40/02
Filed: 1923-08-02
Abstract: 217,791. Harrison, C. H. Aug. 2, 1923. Stone, hardening.-In making artificial stone by subjecting a compressed mass of comminuted stone and lime to the action of carbon dioxide, the following conditions are observed : (1) the water-content of the mass is adjusted to the proportion most favourable to carbonation, (2) the gas pressure is gradually increased, and (3) cooling means are used to prevent excessive rise of temperature. A suitable proportion of moisture is 3-7¢ per cent; it may be obtained either by controlled drying of the mass or by completely drying it and subsequently dipping it in water. The gas pressure may be raised in 4 hours up to 300 lbs. per sq. in. The temperature should be prevented from rising above 80‹ C.; this may be effected by using cooling coils or by previously compressing and cooling the gas and allowing it to expand on entering the hardening chamber.
