TheVat Posted January 7 Share Posted January 7 https://www.sciencealert.com/we-finally-know-how-ancient-roman-concrete-was-so-durable Recent research finds that lime clasts in Roman concrete, formerly thought to be poor mixing, served a vital purpose. (I was first introduced to the wonders of Roman concrete in Robert Harris' novel, Pompeii) Maybe this could help save those seaside condo foundations in Florida that are so beset with problems. 1 Link to comment Share on other sites More sharing options...
