Cement Plants: Cement from Waste Materials

As the chalk stockpiles depleted, and when iron coal-ships with pumpable water ballast were developed, these plants ended up shipping chalk from the Thames as commercial cargoes, until they gave up the ghost due to the resulting high production cost. In many cases, the shut-down of coastal trade during WWI was decisive.
