两千年前的混凝土是什么配方？Augustus ensured that Marcellus’ loss was commemorated within the very topography of Rome through the creation of the 20,000 seat Theatre of Marcellus, at the foot of the Capitoline Hill, inaugurated by the Emperor in 12 BC.[-] John_Best_14425 | 1 points | Feb 19 2022 05:05:15
你好，已经失传了。
原材料是特殊的火山灰。
目前有现代意大利学者的复原。但也未必准确。

和今天的混凝土唯一的不同是里面有火山灰好像，里面是罗马水泥外面包一层钻砖头，因为里面没有钢筋之类的东西做骨架所以大多胀开来，把外面的砖头和大理石片给撑坏，不知道他们有没有在里面加木料做骨架
