#1 it is well-suited for use in salt water and other environments that are too corrosive for regular cement.

He'll get call from Hamas any day now.

#3 We can't make cement that doesn't crumble in a few years. The Romans still have stuff up.

#4 The Romans didn't have 80,000 lb trucks and they salted their enemies' fields, not the roads.

#5 Uh huh. Used steel dust. Pull the other one.

For corrosive environments, Type V cement is already used with limited water/cement ratio and limited Flyash (all hail Alaska Paul!) or slag.

#6 #4 The Germans roads carry freight too, but don't crumble as fast. They don't have the local road building graft that has two or three options of local 'providers' who redo stretches of road every decade (or less) or the local patronage system to hire those teams constantly out filling potholes.

#7 Even better, what if we mixed the used steel dust with powdered aluminum from discarded beverage cans? It's a recycling two-fer!

#8 In many jurisdictions, road building / repair is considered the "cross-eyed brother-in-law employment project" by the politicians.

#10 We could make Roman concrete:

Pliny wrote that the best maritime concrete was made from volcanic ash found in regions around the Gulf of Naples, especially from near the modern-day town of Pozzuoli. Its virtues became so well-known that ash with similar mineral characteristics—no matter where it was found in the world—has been dubbed pozzolan.

#12 In the previous century, I was woking in a machine shop. One of the inspectors heard that iron was a good additive for flower beds. So long about December he got a 5 gal pail of cast iron dust from the mills a took it home and dumped it in his flower bed.
Come Feb his wife is ready to plant flowers, and he has to rent a jackhammer to get the rusted layer out of his flowerbed.
