If roman concrete was shown to have self-healing capabilities, why isn’t it used with modern reinforcement techniques?

213 viewsEngineeringOther

As the title suggests. If roman concrete supposedly has the capabilities to mend tiny cracks via chemical reaction, why isn’t it used with modern reinforcements to seal the pathways to the steel beams to protect it from oxygen and elements and prevent corrosion? Are there any major downsides to hot-mixed concrete, is it not as good as the studies make it out to be, or is it simply not viable due to cost and manufacturing process/storage requirements?

Just because it has the ability to self-heal in some situations doesn’t mean it’s better.

We have the added advantage of 2000 years of development and advances in material sciences.

A weaker concrete that self-heals is much less useful than stronger concrete that doesn’t get damaged in the first place.
