M7.5 ready-mix
concrete
M7.5 is the lowest standard grade — used purely as a non-structural fill or levelling layer beneath reinforced concrete. No rebar, no load.
M7.5 mix design parameters
IS 456:2000 durability minimums for the not for rcc exposure class. Project-specific mix designs are signed off by our QC team.
Where M7.5 fits — and where it doesn't
Specifying the right grade saves money and avoids rework. Below is a quick guide based on IS 456 norms and our delivery experience in Prakasam district.
Use M7.5 for
- Foundation blinding (75 – 100 mm PCC layer below footings / raft)
- Levelling course under column bases and pile caps
- Mass fill in non-loadbearing trenches
- Sub-grade for cement-concrete roads (where M10 is over-spec)
- Garden / pathway base where strength is not critical
Don't use M7.5 for
- Any RCC element — slabs, beams, columns, lintels
- Compound walls or pavements with embedded steel
- Water-retaining structures
How we batch M7.5
Per IS 456:2000, M7.5 is classified as ordinary grade and is permitted only for plain concrete in non-structural roles. There is no IS 456 minimum cement content for this grade because it does not carry load or protect embedded steel. Typical mix uses 200 – 240 kg/m³ cement.
Every dispatch from our Mallavarappadu and Gundlapalli plants includes a batch slip with mix proportions and a 28-day cube test report — generated from the same load you receive. M7.5 is delivered in transit mixers and placed either by direct chute discharge or by line pump for upper-floor slabs, columns, and pours the truck can't reach. For projects above 50,000 m³, we can set up a dedicated batching plant on your site with a project-specific mix design and on-site QC lab.
