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

243 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?

Its more expensive.

All the supposed benefits of Roman concrete are well known today, and we can make concrete significantly better in every way than they did. So why dont we?

Cost. Thats it. It costs more, and building today is all about controlling costs.

We could make glass fiber reinforced concrete with self healing properties and whatever else. The building would last 1000 years. But the client is paying for a building that lasts 100 years, not 1000. So we build it for what is being paid for.
