研究发现罗马混凝土,而CO2含量较高,排放的空气污染物比现代版本少。 Study finds Roman concrete, while high in CO2, emits fewer air pollutants than modern versions.

最近的一项IScience研究将罗马混凝土对环境的影响与现代版本相比较。 A recent study in iScience compares the environmental impact of Roman concrete to modern versions. 尽管罗马混凝土产生类似或更高的CO2排放量,但排放的氧化氮和氧化硫等空气污染物却大大减少。 Though Roman concrete produces similar or higher CO2 emissions, it emits significantly fewer air pollutants like nitrogen oxide and sulfur oxide. 由火山灰和石灰制成,具有持久性和长期性,有可能减少频繁更换的需要。 Made from volcanic ash and lime, it is durable and long-lasting, potentially reducing the need for frequent replacements. 研究人员认为,这些古老的方法可以提供教训,使今天的混凝土更具有可持续性。 Researchers suggest these ancient methods could offer lessons for making today's concrete more sustainable.
