罗马混凝土通过热混合方法与火山灰进行自我修复, Roman concrete self-repaired via hot-mix method with quicklime and volcanic ash, MIT study finds.

发现古罗马人使用“热混合”方法使自我愈合混凝土, 在加水、制造热和耐久的石灰罩以修补裂缝之前, 将快速石灰与火山灰混在一起, A newly uncovered construction site in Pompeii, buried in 79 CE, reveals ancient Romans used a "hot-mix" method to make self-healing concrete by mixing quicklime with volcanic ash before adding water, creating heat and durable lime clasts that repair cracks. 这一先进技术得到麻省理工学院研究人员的证实,并在《自然通信》中发表,与以前基于维特鲁维乌斯的信念形成鲜明对比,显示罗马人通过精密、有意的工程实现了长期结构。 This advanced technique, confirmed by MIT researchers and published in Nature Communications, contrasts with earlier beliefs based on Vitruvius and shows Romans achieved long-lasting structures through sophisticated, intentional engineering. 这一发现为罗马建筑提供了新的洞察力,并可能在今天激发出更可持续、更持久的混凝土。 The discovery offers new insights into Roman construction and may inspire more sustainable, durable concrete today.
