Joseph Aspdin | Encyclopedia
Concrete, a mixture of cement, gravel, and sand, had existed since the time of the Romans. However, the cement portion was often of uneven quality. Aspdin discovered that the key to making hydraulic cement (cement that would harden when mixed with water) was roasting a mixture of clay and limestone powder in a furnace.
