Concrete is defined as a mixture of cement sand, gravel and water which dries hard and strong and is used as a material for building.
Basic Concrete Mixtures
- Typical concrete is made out of two different types of aggregate substances: a course aggregate such as gravel and a fine aggregate such as sand.
- Along with the aggregates is cement, which is generally composed of different kinds of ash and limestone.
- A chemical additive is used in concrete which activates when water is added to the concrete. The chemical additive acts as a catalyst for the setting and drying of the concrete in order to make it hard and dense.
- When the concrete mixture is created to act as a finish with a desired effect, such as for architectural or aesthetic effects, there are other chemical additives that may be added such as dyes or specific chemicals that are designed to make the concrete behave a certain way.
- Concrete roads or structural surfaces are made out of reinforced concrete made with iron bars, called rebars.
- When concrete is used vertically, as in walls or building structures, the foundation of the structure must also be constructed of concrete, and must be footed into the ground anywhere from four to eight feet.
An example of concrete is what many driveways are made of.
