Gradation Carbonated Recycled Aggregate

Carbonation-enhanced recycled material

Recycled cement concrete is sieved into size grades and carbonated individually, yielding aggregates and powders with improved physical properties and interfacial strength over non-carbonated recycled materials, ready for use in artificial stone production.
