摘要: The reaction of fresh lightweight concrete with carbon dioxide during early-age carbonation curing is hindered by surface saturation due to vibration consolidation. To promote a high degree concretes, dynamic system was developed remove free water and inject simultaneously. Based on cement mass, the resulting uptake reached 13% in 4 h 20% 18 carbonation. early strength comparable that steam curing, while late higher much reduced process time. can effectively control relative humidity chamber prevent accumulation create route capillaries for diffusion precipitation carbonates. Dynamic creates carbonate–bond matrix. provides an excellent means recycle dioxide, economic environmental benefits.
