However, more feasible and simple technologies now require for making sustainable material recycling because social procedures and industrial processes in recycling are still reluctant. In this research, the recycled aggregates were feasibly made from crushed concrete wastes with conventional rod milling machineries and cured in CO2 gas due to enhancement of surface density. Curing in CO2 gas of recycling aggregate and byproduct powder contribute to reduction of water absorption, and it improves concrete compressive strength. However, concrete introducing byproduct concrete powder modified in CO2 gas, still extend drying shrinkage.
