abstract = "Urbanization and reconstruction pose ecological challenges due to resource overexploitation and high CO2 emissions associated with construction. Waste concrete powder (WCP), often discarded in landfills, is explored for its potential in non-structural blocks. This research delves into the sequestration capabilities of WCP through laboratory investigations, specifically when treated with a polyvinyl alcohol (PVA). PVA was selected for its compatibility with cementitious matrices and its ability to form uniform, cohesive polymer films that enhance particle bonding, improve microstructural integrity, and retain moisture. The results reveal that polymer treatment leads to a 27.7 % increase in the compressive strength of WCP compared to the untreated sample. This enhancement is attributed to the elevated content of calcium carbonates and improved microstructure of the WCP when its particles are coated with polymer films and interconnected by bridges, as confirmed by microstructure tests. Polymer facilitates the improvement of the sequestration properties of WCP, evident in the increased mass loss during thermogravimetric analysis (TGA). Extending the carbonation time from 2 to 6 hours for PVA-treated WCP compacts resulted in CO2 absorption of 24.06 and 9.59 kgCO2 according to the mass gain and TGA methods.",
