In this video, I discuss a few modern techniques that help improve design life of concrete, including roller compacted concrete (RCC) and water reducing admixtures (superplasticizers). There are a whole host of differences between modern concrete and that of the western Roman empire that I didn’t have time to go into, including freeze/thaw damage. This is such and interesting topic, so here are some references if you’d like to learn more:
