Ready Mix Concrete

Batching-plant concrete in M10 to M40 and above, delivered by transit mixer.

Product overview

Ready mix concrete (RMC) is batched by weight at a plant, mixed to a designed grade and delivered in a transit mixer. Compared with site mixing you get consistent strength, no material storage on site and far faster pours.

The trade-off is logistics. Concrete must be placed within its initial setting window, so access, pump position and pour sequence have to be planned before the first mixer leaves the plant.

Typical units: cubic metre. Quoted per cubic metre by grade; pumping charges and demurrage are usually extra.

Common applications

  • Slabs, rafts and large pours
  • Columns, beams and shear walls
  • Pavements, driveways and industrial floors
  • Pile caps and foundations
  • PCC and levelling courses

Available grades and variants

M10 / M15
PCC, levelling and non-structural work.
M20 / M25
Standard residential structural concrete.
M30 / M35
Commercial structures and heavier loading.
M40 and above
High-rise columns, precast and special applications.

Buying guide: ready mix concrete

  • Order by grade and cubic metre, and confirm slump at the site — not at the plant.
  • Plan the pump, access road and pour sequence before booking; waiting mixers cost demurrage.
  • Take cube samples for every pour and get the 7-day and 28-day test results.
  • Never allow water to be added at site to improve workability; ask for a plasticiser instead.

Ready Mix Concrete FAQs

Is RMC cheaper than site-mixed concrete?

Per cubic metre it often costs a little more, but consistent strength, no wastage, no storage and much faster pours usually make it cheaper overall on anything above a small slab.

What slump should I specify?

Typically 75–100 mm for regular placement and 100–150 mm for pumped concrete, adjusted with admixtures rather than added water.
