In this study, the role of natural additives (sodium chloride or sugar) in aerial lime mortar was elucidated. It was found that both the hydration and carbonation were accelerated by sodium chloride but retarded by sugar. Especially, sugar prevented the rapid clogging of pores around the mortar surface, which caused the even formation of calcium carbonate crystals throughout the volume of mortar. Therefore, the strength development was significantly accelerated. The slow carbonation and resulting rapid strength development can be practically implementable since it does not rely on long term atmospheric carbonation or use of high concentration of CO₂ gas.

控制石灰基材料中的水合和碳化：CO ₂可固化建筑材料中缓慢碳化的优势

在这项研究中，阐明了天然添加剂（氯化钠或糖）在航空石灰砂浆中的作用。发现氯化钠促进了水合和碳酸化，但糖阻止了水合和碳酸化。特别是，糖阻止了砂浆表面周围孔的快速堵塞，从而导致整个砂浆中碳酸钙晶体的均匀形成。因此，强度发展显着加快。缓慢的碳化和由此产生的快速强度发展可以实际实现，因为它不依赖于长期的大气碳化或使用高浓度的CO ₂气体。
