Perhaps the greatest step forward in the modern use of concrete was Smeaton's Tower, built by British engineer John Smeaton in Devon, England, between 1756 and 1759. This third Eddystone Lighthouse pioneered the use of hydraulic lime in concrete, using pebbles and powdered as aggregate.

Reactive Powder Concrete (RPC) was developed in France in the early 1990s and the world’s first Reactive Powder Concrete structure, the Sherbrooke Bridge in Canada, was erected in July 1997. It consists of a special concrete where the microstructure is optimized by precise gradation of all particles in the mix to yield maximum density.

 · I'm relatively new to melting metal, though I have built 3 foundries up till now so I have the basics and safety down pretty well. Just a few weeks ago I got my hands on some Hard Firebrick (rated for up to 2700 F / 1482 C) and built my third foundry (all of mine burn charcoal though I have been taking a look into propane).
