But if a concrete slab is reinforced with a network of small steel rods on its undersurface where the tensile stresses occur, its strength will be enormously increased. Reinforced concrete =the perfect mix of form and strength.

Concrete hardens through a chemical process called hydration. For hydration to take place, concrete must have a minimum water-to-cement ratio of 25 parts of water to 100 parts of cement. Water in excess of this ratio is surplus water and helps make the concrete more workable for placing and finishing operations.
Their concrete did not dry as quickly as that made with Portland cement, and time is money on many projects. What the Berkeley researchers hope is that the concrete industry will take a look at their practices and possible learn something from the Romans....Chat Now

The history of concrete is tied to the history of cement a binding material, typically derived from limestone, so important to making concrete that the two terms are practically synonymous. Middle Eastern builders knew of the importance of limestone as early as 1300 B.C., when it was used to coat the walls of buildings, becoming hard with exposure to air.
