•Ready mix concrete is concrete that is made at ready-mixed plant and then transported to the site in rotating-drum trucks or transit mixers.
•Proportioning, batching, mixing and delivery are all done by the concrete supplier.
•High quality control
•Advantages of using ready mix concrete:
•Proportioning, batching, mixing and delivery are all done by the concrete supplier.
•High quality control
•Advantages of using ready mix concrete:
a) better quality concrete due to usage of trained personnel and automated equipment.
b) elimination of material storage on congested building sites- no need to allocate place at site for storage of cement, aggregate, sand
c) save the contractor’s time and usage of labour’s energy to mix the concrete

•For ready mix concrete supply, the purchaser should specify the following:
a) Designated max. size of coarse aggregate
b) Desired / max. slump at the point of delivery
c) Air content (for air entrained concrete)
d) Mix design requirement – such as cement content, max. water content & admixtures or minimum compressive strength at 28 days
e) Unit weight required (for structural lightweight concrete).
