MANUFACTURING METHOD OF RECYCLED AGGREGATES USING REACTION OF RAPID CARBONATION

摘要

PURPOSE: A method for producing a recycled aggregate is provided to charge air gap of cement with calcium carbonate and improve the quality of recycled aggregate. CONSTITUTION: A method for producing a recycled aggregate comprises: a step of adding one or more mixture selected from thick aggregate of 5-25 mm, thin recycled aggregate of 0.01-5mm, or recycled aggregate of 0.01-40 mm into a closed chamber; a step of stirring the recycled aggregates; and a step of reacting at -10-100°C, 2-7 pressure while supplying 6-100% of carbon dioxide for 5-30 minutes.
