Steel was known in antiquity and was produced in bloomeries and crucibles. The earliest known production of steel is seen in pieces of ironware excavated from an archaeological site in Anatolia (Kaman-Kalehöyük) and is nearly 4,000 years old, dating from 1800 BC.

Cement was first developed by Joseph Aspdin, an enterprising 19th century British Stonemason, who heated a mixture of ground limestone and clay in his kitchen stove, then pulverized the concoction into a fine powder.

The first recorded version of the portable concrete mixer was horse-drawn. It was invented in 1904 by a German inventor called Richard Bodlaender who gave it the title "Mortar Mixer".

The front wheels were replaced by a large drum that contained paddles for churning the concrete and as the horses pulled the vehicle, the wheel would turn, creating the mixing action. This machines was extremely heavy and would take horses a long time to transport the mixer from place to place.
