Was Roman Concrete Better?
推荐理由
Here's a good video on the use and tradeoffs of Roman concrete engineering
说明
这是2018年由Practical Engineering发布的一部讲解,主题归在Civil engineering & construction。它讲的是roman vs modern concrete这一支里的具体问题,而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成:Practical Engineering compares modern concrete with that of the Roman Empire, covering modern techniques like roller compacted concrete and water-reducing admixtures. It explains the tradeoffs of Roman construction versus reinforced concrete.这些读者给出的理由,核心是:HN recommends it as a clear, balanced answer to claims that Roman concrete was better than ours.讲法不绑某一条新闻,过几年仍然可以当材料看。从2021年到2024年,有4位不同的读者在3个不同月份把它推荐出来,其中明确叫别人去看的有0次。适合用一集把一个概念补上的人。抓住它用的那个图像或类比,比背公式重要。如果已经会了基本定义,就把注意力放在它怎么把roman vs modern concrete变成能跟着复述的例子。
