ready mixed Concrete by Sjc Group  is one of the most widely used construction materials, and it is made from three basic components: water, aggregates, and Portland cement. The construction industry uses two main types, which are called ready mix concrete , and site mixed concrete. Selecting the right type for a project is very important: both types have their own specifications, advantages and disadvantages. While both types are viable in concrete construction,

one may be more beneficial than the other depending on project conditions.

Ready-mix concrete is manufactured in a plant and delivered to the construction site

in an unhardened and plastic state, ready for use.

usually expressed in cubic meters.

Transit-mixed (also known as truck-mixed) concrete,

materials are batched at a central plant and are completely mixed in the truck in transit.

Frequently, the concrete is partially mixed in transit and mixing is completed at the jobsite.

Transit-mixing keeps the water separate from the cement and aggregates and allows the concrete to be mixed immediately before placement at the construction site.

This method avoids the problems of premature hardening and slump loss that result from potential delays in transportation or placement of central-mixed concrete. Additionally, transit-mixing allows concrete to be hauled to construction sites further away from the plant. A disadvantage to transit-mixed concrete, however, is that the truck capacity is smaller than that of the same truck containing central-mixed concrete.
