WATER RETENTIVITY CONTROLLABLE CONCRETE PRODUCT CAPABLE OF CONTROLLING WATER RETENTIVITY AND WATER PERMEABILITY

摘要

PPROBLEM TO BE SOLVED: To provide a water retentivity controllable concrete product capable of controlling water permeability and water retentivity and having excellent strength which is obtained by adding aggregate comprising slag into particles obtained by the pulverization of waste concrete. PSOLUTION: The water retentivity controllable concrete product capable of controlling water permeability and water retentivity and having excellent strength is obtained by adding at least one slag of molten slag, electric furnace slag and blast furnace slag each having 2.5-5 mm particle diameter into the particle obtained by the pulverization of the waste concrete and having 0.3-5 mm particle diameter, further adding cement and water, forming the mixture by the combination of vibration and compression and steam-aging.
