1. A method for a concrete production, comprising:

mixing of a calcium carbide residue (CCR) and ordinary Portland cement (OPC) to produce CCR-OPC blended concrete;

incorporating the CCR-OPC blended concrete in its fresh or semi-hardened state to a carbonation chamber for accelerated carbonation curing of the semi-hardened CCR-OPC blended concrete; and

producing carbonated CCR-OPC blended concrete after the accelerated carbonation curing.
