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. 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.
Transit Mixer in late 1950’s

5. Need for Ready Mix concrete
 Requirement for higher grades of concrete
 Correct accountability ingredients
 Rapid development of infrastructure industry
 Increased demand of concrete
 Possibility of manufacture of desired grades
 Mega project demands higher output
 Timely supply of reliable concrete

6. Progressive growth of Ready mix concrete

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
