3. Ready Mix Concrete - Definition
“Ready mix concrete is concrete whose components are proportioned away from the construction site for delivery to the construction site by the truck in a ready-to-use-condition.”

4. Transit Mixer in late 1950’s
History
In 1909, the residents of Sneridan, Wyoming could have witnessed the birth of Ready Mix concrete industry.
Prior to World War I, concrete was produced in stationery plant mixer hauled to construction sites in dumps trucks.

7. Advantages Of Ready Mix Concrete
Quality assurance
Elimination of manual errors
Mass production of concrete possible
Water cement ratio maintained
Reduced material wastage
Labour cost saved
Design mix as per IS standards resulting in standard deviation and improved characteristics.

8. Disadvantages Of Ready Mix Concrete
The materials are batched at a central plant, and the mixing begins at that plant
Generation of additional road traffic; furthermore, access roads, and site access have to be able to carry the weight of the truck and load.
Concrete's limited time span between mixing and going-off
