【発明の名称】経時硬化性混合物からの物体とくに建築用ユニット部材の製造方法とその装置
Document Type and Number:
Japanese Patent JPH0639087
Kind Code:
B2
Abstract:
To produce articles, especially building elements from a material mixture which contains cement or/and lime as binder and is to be cured, the raw mixture is filled continuously into a template (1) and pressed in by ramming. CO2 gas at superatmospheric pressure flows through the mixture in the template space (5), whereby the mixture is cured by means of an instantaneous carbonating reaction to give a moulded article. Escape of the CO2 gas in the surroundings of the feed opening of the template (6) is prevented by making the material virtually gas-tight by mechanical means, for example by ramming it in. In the direction of the outlet opening (7), the pressure of the CO2 gas is reduced and, in the region of the outlet opening, the quantity of CO2 gas fed is then only just that which is still required for the chemical reaction. Consequently, there is not even a gas loss here. The continuously issuing article is cut to measure, for example by means of a saw (21).
