Is cement stronger than concrete? Cement is not stronger than concrete . On its own, in fact, cement is prone to cracking. When combined with aggregate materials and water and allowed to harden, however, cement—now concrete—is extraordinarily strong.
Who invented concrete?
In 1824 Joseph Aspdin invented Portland cement by burning finely ground chalk and clay until the carbon dioxide was removed. Aspdin named the cement after the high-quality building stones quarried in Portland, England. In the 19th Century concrete was used mainly for industrial buildings.
Why is concrete important?
In the construction industry, concrete is most commonly used as the foundation for most structures . It is also used in superstructure construction through the use of structural concrete, slab construction, stair construction, and architectural features.

What is the most common type of concrete?
Standard ready-mix concrete is the most common form of concrete. It is prepared for delivery at a concrete plant instead of mixed on the construction site, which guarantees the quality of the concrete. This type of concrete can provide a structural function, as well as an aesthetic or decorative finish.
