根据一项新的麻省理工学院研究,美国混凝土每年吸收650万吨二氧化碳,抵消水泥排放的13%。 U.S. concrete absorbs 6.5 million tons of CO₂ yearly, offsetting 13% of cement emissions, per a new MIT study.

美国建筑和基础设施的水泥每年通过自然碳化吸收650万公吨二氧化碳,抵消水泥生产产生的约13%的排放量。 Cement in U.S. buildings and infrastructure absorbs over 6.5 million metric tons of CO₂ annually through natural carbonation, offsetting about 13% of emissions from cement production. MIT一项新的研究发现，墨西哥每年大约储存500万吨碳水，这得益于更高的砂浆使用和现场混合。 A new MIT study finds Mexico sequesters roughly 5 million tons yearly, aided by higher mortar use and on-site mixing. 这一过程因结构类型、气候和材料比率而异,多孔迫击炮吸收二氧化碳的速度快于密度大的混凝土。 The process varies by structure type, climate, and material ratios, with porous mortars absorbing CO₂ faster than dense concrete. 研究人员利用具有代表性的建筑模型估计全国的吸收程度,敦促更新气候报告,以反映实际世界的碳混凝土储存。 Researchers used representative building models to estimate uptake nationwide, urging updates to climate reporting to reflect real-world carbon storage in concrete.
