The Assyrians and Babylonians used clay as cement in their concretes. The Egyptians used lime and gypsum cement. In the Roman Empire, concrete made from Quicklime, pozzolanic ash/pozzolana and an aggregate made from pumice was very similar to modern portland cement concrete. In 1756, British engineer John Smeaton pioneered the use of portland cement in concrete, using pebbles and powdered brick as aggregate. In the modern day, the use of recycled/reused materials as concrete ingredients is gaining popularity due to increasingly stringent environmental legislation. The most conspicuous of these is pulverized fuel ash, recycled from the ash by-products of coal power plants. This has a significant impact in reducing the amount of quarrying and the ever-attenuating landfill space.

Brits actually invented the word. "Soccer," when it first appeared in the 1890s, was spelled "socca," which was short for "association" or "association football," meaning football played according to the rules laid down by the British Football Association. It was also called "socker" until the current form "soccer" appeared around 1895.

During World War 1 with the production of mustard gas, a residue would build up within the catalytic chamber.  This residue was polyethylene, the first real plastic.  It was not commercially manufactured for many more years. The bakelites commonly referred to as the first plastics were actually the first composites. They are not plastics at all, they were named prior to the final definition of plastic being established.
