Introduction
Concrete comes in various strengths and ratios, each designed for a specific purpose. Among the most widely used for non-structural applications is the C10 concrete mix ratio. While not as strong as higher grades like C25 or C35, it plays a crucial role in creating reliable foundations, sub-bases, and domestic projects.
According to the Concrete Centre UK, lower-grade mixes such as C10 and C15 account for nearly 35% of domestic concrete applications, including garden paths, kerbing, and shed bases. For UK homeowners and contractors, understanding C10 concrete is essential to avoid using a stronger (and more expensive) mix than necessary.
What Is the C10 Concrete Mix Ratio?
The C10 concrete mix ratio is designed to achieve a compressive strength of 10 N/mm² at 28 days. Its typical proportion is:
- 1 part cement
- 3 parts sand
- 6 parts coarse aggregates
- Water (adjusted to maintain workability)
This produces a relatively low-strength concrete ideal for non-structural applications where heavy load-bearing capacity is not required.
Properties of C10 Concrete
- Low Compressive Strength – 10 N/mm², sufficient for light-duty uses.
- Workability – Easy to mix and place, even in confined areas.
- Cost-Effective – Uses less cement, reducing material costs.
- Durability – Adequate for bases, kerbs, and domestic settings when properly cured.
Where to Use C10 Concrete in UK Construction
The C10 mix is widely used across both residential and light commercial projects. Typical applications include:
1. Domestic Foundations and Sub-Bases
Perfect for shed bases, conservatories, and garden structures.
2. Kerbs and Pathways
Used for laying kerbstones and garden paths.
3. Blinding Concrete
Applied as a thin layer before pouring structural concrete, providing a level surface and preventing contamination.
4. Non-Structural Fill
Ideal as a fill material where strength is not critical.
5. Light-Duty Pads
Used for small footings, patios, and landscaping projects.
C10 vs. Other Concrete Grades
| Grade | Strength | Typical Applications |
| C10 | 10 N/mm² | Shed bases, kerbs, blinding |
| C15 | 15 N/mm² | Domestic floors, pathways |
| C25 | 25 N/mm² | Driveways, footings, house floors |
| C35 | 35 N/mm² | Industrial floors, foundations |
C10 is not suitable for structural load-bearing, but it’s the most economical and practical choice for light-duty applications.
Benefits of Using C10 Concrete Mix Ratio
- Cost Savings – Less cement reduces costs, making it ideal for budget-friendly projects.
- Ease of Use – Simple mix that’s easy to place and finish.
- Waste Reduction – Using the correct grade avoids overspending on stronger, unnecessary mixes.
- Eco-Friendly – Lower cement content means reduced carbon footprint.
- Reliable for Small Projects – Perfect for non-structural, domestic applications.
Facts & Figures: C10 Concrete in the UK

FAQs
Q1: What strength is C10 concrete?
C10 achieves a compressive strength of 10 N/mm² at 28 days, making it suitable for light-duty work.
Q2: Can C10 be used for house foundations?
No. It’s too weak for structural foundations. Stronger grades like C25 or C35 are recommended.
Q3: Is C10 concrete cheaper than other mixes?
Yes. Its lower cement content makes it one of the most cost-effective mixes.
Q4: How long does C10 concrete last?
With proper curing and maintenance, it can last 25–30 years in non-structural uses.
Q5: What’s the most common use of C10 in the UK?
It’s widely used for blinding layers, shed bases, and kerbing.
