C60 Concrete (60N) – Uses, Price & Delivery in London
For the most demanding structural requirements, C60 concrete is a top-tier, high-specification mix designed for maximum durability in aggressive environments. With a standardised formula, it attains a strength rating of 60 newtons after a curing period of 28 days. C60 is frequently used in complex engineering projects that require the highest levels of compressive strength and longevity.
C60 is ideal in the following applications:
- Nuclear and hazardous waste containment structures
- Major hydraulic and water-retaining infrastructure
- Specialised offshore energy and deep-sea platforms
C60 Concrete – Free Delivery in London & Surrounding Areas
C60 concrete is an ultra‑high‑strength, premium‑grade concrete mix engineered for the most demanding structural applications. With a characteristic compressive strength of 60 N/mm², it sits at the very top of the standard concrete strength classifications used in domestic construction. C60 is designed to withstand extreme loads, aggressive environmental conditions, chemical exposure, and continuous mechanical stress, making it the ideal choice for projects where maximum durability and structural integrity are essential.
Although C60 is more commonly associated with commercial and civil engineering projects—such as bridges, high‑rise buildings, industrial floors, and infrastructure—it also has important uses in domestic construction. When a homeowner or contractor requires a concrete solution that will last for decades under intense pressure, C60 provides unmatched performance. It is the mix of choice for large retaining walls, structural foundations, heavy‑duty slabs, and bases supporting exceptionally heavy loads such as swim spas, machinery, or multi‑room garden buildings.
C60 is not a general‑purpose concrete. It is a specialist mix chosen for specific, high‑demand applications where lower‑strength concretes simply would not be sufficient. When used correctly, C60 delivers extraordinary longevity, stability, and resistance to cracking, settlement, and environmental degradation.

C60 Technical Characteristics
Strength Rating
- 60 N/mm² compressive strength at 28 days.
- Often equivalent to RC50/60 in structural specifications.
This strength level makes C60 suitable for heavy structural foundations, reinforced slabs, and high‑load domestic applications.
Workability
Despite its density and high cement content, C60 can be supplied with a workable slump that allows for:
- Efficient compaction
- Smooth finishing
- Compatibility with reinforcement
- Reliable performance in both warm and cool conditions
However, C60 requires more precise handling than lower‑grade mixes due to its density and rapid strength gain.
Setting Time
Typical setting times include:
- Initial set: 2–3 hours
- Final set: 6–8 hours
- Full cure: 28 days
C60 can usually be walked on within 24–48 hours and built upon shortly after, depending on weather conditions.
Mix Composition
C60 contains:
- A very high cement content
- High‑quality fine and coarse aggregates
- Low water‑cement ratio
- Optional admixtures such as plasticisers, retarders, accelerators, silica fume, or air entrainers
The mix is engineered for maximum strength, density, and durability.
Material Compatibility
C60 is compatible with:
- Steel reinforcement
- Damp‑proof membranes
- Concrete blocks and bricks
- Timber formwork
- Compacted MOT Type 1 sub‑bases
Avoid using C60 in:
- Sulphate‑rich soils without specialist cement
- Applications where flexibility is required
Projects where lower‑strength mixes are more cost‑effective
Customer Testimonials
“We used C60 for the base under our swim spa, and it’s been absolutely rock‑solid. The finish is excellent, and even with the enormous weight of the spa, there’s been no movement or cracking. It’s exactly what we needed for a long‑lasting solution.”

Questions we are often asked about C60 Concrete
C60 is an ultra high‑strength concrete used for major structural elements, heavy civil engineering works, high‑load beams and infrastructure requiring exceptional strength.
Yes. C60 provides very high compressive strength suitable for bridges, columns, reinforced beams, and critical load‑bearing components.
C60 offers outstanding durability and long‑term performance, making it ideal for structures exposed to heavy loads, harsh weather, or high traffic.
C60 reaches a compressive strength of approximately 60 N/mm² after 28 days.
Yes. C60 can be pumped with appropriate admixtures such as superplasticisers to maintain workability due to its high cement content.
C60 begins initial set within a few hours depending on temperature, with full curing requiring around 28 days.
C60 is more expensive than lower grades but offers exceptional value in high‑strength, long‑lasting structural applications.
