摘要: Abstract As an ideal cementitious material for the maintenance of historic buildings and replacement interior decoration mortars, widespread application natural hydraulic lime (NHL) is expected to play important role in CO2 capture utilization. Structures properties NHL2 mortars with nano-SiO2 (NS) under carbonation were researched this paper. NHL could during hardening process air-hardening contents, captured would be fixed matrix form CaCO3. Carbonation percentage extent increased by addition NS whatever atmospheric or accelerated condition. Much more compacted surfaces than that uncarbonated region was observed. The will reduce porosity big pores (approximately 1 μm) while increase mesopores 50 nm) mortars. reaction seemed improved NS, which beneficial collection, solidification further utilization CO2.
