VEGETATION BLOCK FOR CONCRETE AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A concrete vegetation block and a manufacturing method thereof are provided to manufacture a concrete vegetation block suitable for plant growth by lowering pH to 7.5~10. CONSTITUTION: A manufacturing method for a concrete vegetation block is as follows. A shaped cement concrete block is cured. The cured cement concrete block is placed in a chamber filled with water. The chamber in which the cement concrete block is placed in is closed. A specific pressure is maintained by injecting CO2 into the chamber so that the C/Ca mol ratio in which the Ca of the cement concrete block and the C of the CO2 are reacted maintains a 0.1~10 reaction. A concrete vegetation block is formed by lowering pH to 7.5~10 by reacting the Ca(OH)2 of the cement concrete block with CO2. The concrete vegetation block is discharged using air pressure.
