CONCRETE PAVEMENT RECYCLED FROM WASTE CONCRETE

摘要

Provided is a concrete pavement recycled from waste concrete to make the best use of waste concrete from degraded buildings, which is excellent in water permeability, water retainability, and economic value by adding cement to the concrete. The concrete pavement or pavement block(1) is produced by mixing waste concrete particles obtained by pulverizing waste concrete materials, the concrete particles consisting of 5wt% (or less) of particles with a diameter of 0.3mm or less and 3wt% (or less) of particles with a diameter of 5mm or larger, 17-20wt% of dry cement, and 15-25% of water; molding the resultant mixture under high-vibration and high-pressure conditions; and curing the mold obtained through a stripping process in a steam saturated atmosphere for 24 hours or longer.
