The role of recycled waste glass incorporation on the carbonation behaviour of sodium carbonate activated slag mortar

This study investigates the influences of recycled waste glass powder (RGP) on carbonation behaviour sodium carbonate activated ground granulated blast furnace slag (GGBS) mortars. The effect activator dosages, types and RGP addition resistance to are evaluated. results indicate a high dosage or water combination as always can enhance ability carbonation. Furthermore, 30% in GGBS binder system seems significantly improve shrinkage is reduced after incorporation; at same time, higher strength performance observed. blends shows no influence species reaction products. However, carbonation, sample containing promotes formation nahcolite, while less bound loss calcium identified. A volume gel pores (<10 nm) formed compared specimens only GGBS. These properties contribute better for
