Basic Ingredients of Ready Mixed Concrete

Ready-mixed concrete refers to blended concrete to be delivered from a central plant instead of being mixed on-site. Each batch of ready-mixed concrete is specially manufactured to the needs of the customer and is delivered to the contractor in cylindrical trucks, these cylindrical trucks are commonly known as cement mixers, in a plastic form. Ready mixed concrete which provides many conveniences for the consumer is also very useful and considerably convenient for usage.

Basic Ingredients of Ready Mixed Concrete

There are three basic ingredients in ready-mixed concrete. They are listed below.

Portland Cement: The cement and water form a paste that coats the aggregate and sand in the mix. The paste hardens and binds the aggregates and sand together.

Water: Water is needed to chemically react with the cement (hydration) and to provide workability with the concrete.

Aggregates: Sand is the fine aggregate for ready-mixed concrete. Gravel or crushed stone is the coarse aggregate in most mixes that use for ready-mixed concrete.

Desired Properties of Concrete

  1. The concrete mix should be workable: It can be placed and consolidated properly by customers or workmen.
  2. Desired qualities of the hardened concrete should be met: for example, resistance to freezing and thawing, deicing chemicals, water tightness (low permeability), wear resistance, and strength. Customers should know what they are trying to achieve with concrete.
  3. Economy: Since the quality depends mainly on the water-to-cement ratio, the water requirement should be minimized to reduce the cement requirement (and thus reduce the cost).

Consumers should discuss how to achieve their goals for concrete with their ready-mix suppliers.

To reduce water and cement requirements, follow the steps that listed below:
