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concrete and civil engineering这一支里的具体问题，而不是把整个领域扫一遍。适合第一次接触、还没有先修课的人。内容上可以概括成：Practical Engineering gives a short introduction to concrete, covering the difference between concrete and cement, the ingredients, and reinforcement. It includes a hydraulic press demonstration of compressive strength.这些读者给出的理由，核心是：Commenters link it as an approachable explanation of concrete basics in threads about Roman concrete, construction and sand supply.讲法不绑某一条新闻，过几年仍然可以当材料看。从2018年到2023年，有2位不同的读者在2个不同月份把它推荐出来，其中明确叫别人去看的有1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concrete and civil engineering变成能跟着复述的例子。
