Carbonation and CO2 uptake in rendering mortars produced with recycled construction and demolition waste

Abstract: This paper aims to evaluate the CO2 uptake due to rendering mortar carbonation, produced with different rates of construction and demolition waste (CDW). Three different mortars were produced with the replacement of 0, 50 and 100% natural sand by CDW recycled sand. The CO2 uptake was conducted by thermal analysis for samples exposed to CO2 action in a laboratory environment for 96 days. Results showed that the incorporation of CDW recycled aggregate contributes to the CO2 uptake. Mortars with 100% recycled san… Show more
