What is Concrete?
Concrete Definition: Concrete, an artificial stone-like mass, is the composite material that is created by mixing binding material (cement or lime) along with the aggregate (sand, gravel, stone, brick chips, etc.), water, admixtures, etc in specific proportions. The strength and quality are dependent on the mixing proportions.
The formula for producing concrete from its ingredients can be presented in the following equation:
Concrete = Binding Material + Fine & Coarse Aggregate + Water + Admixture (optional)
Concrete is a very necessary and useful material for construction work. Once all the ingredients -cement, aggregate, and water unit of measurement mixed inside the required proportions, the cement and water begin a reaction with one another to bind themselves into a hardened mass. This hardens the rock-like mass in the concrete.
Concrete is powerful, easy to create, and can be formed into varied shapes and sizes. Besides that, it is reasonable, low cost, and instantly mixed. It is designed to allow reliable and high-quality fast-track construction. Structures designed with the concrete unit of measurement are plenty durable and should be designed to face up to earthquakes, hurricanes, typhoons, and tornadoes. This is an incredible advancement. With all the scientific advances there are in this world, there still has not been a way of preventing nature's injury.
Composition of Basic Concrete Mix
If we evaluate the concrete composition to see what concrete is made of, we can see there are four basic ingredients within the concrete material mix:
Binding materials like cement or lime
Aggregates or Inert Materials
Fine aggregate (sand)
Coarse aggregate (stone chips, brick chips)
Water
Admixture (e.g. Pozzolana)
A brief description of the concrete ingredients is given below.
Binding Materials
Binding material is the main element of a concrete material mix. Cement is the most commonly used binding material. Lime could also be used. When water is mixed with the cement, a paste is created that coats the aggregates within the mix. The paste hardens, binds the aggregates, and forms a stone-like substance.
Aggregates
Sand is a fine mixture. Gravel or crushed stone is the coarse mixture in most mixes.
Water
Water is required to with chemicals react with the cement (hydration) and to supply workability with the concrete. The number of water combined in pounds compared with the number of cement is named the water/cement quantitative relation. The lower the w/c quantitative relation, the stronger the concrete. (Higher strength, less permeability)
