- Setting time: Initial set in 30 minutes, final set in 10 hours
- Fineness: 225-400 m²/kg surface area
- Colour: Standard grey finish
Best Uses for OPC
OPC works perfectly for:
- Residential foundations and footings
- General concrete slabs and driveways
- Structural beams and columns
- Precast concrete elements
- Mortar for brickwork and blockwork
OPC Limitations
Avoid OPC when you need:
- Rapid strength development

Frequently Asked Questions About UK Cement Types
What’s the difference between cement and concrete?
Cement is the binding agent that holds concrete together. Concrete contains cement, water, sand, and aggregates. Think of cement as the glue that makes concrete strong.
How long does cement last in storage?
Properly stored cement lasts 3-6 months. Bag cement degrades faster than bulk cement. Always use oldest stock first and protect from moisture.
Can I mix different cement types together?
Generally not recommended. Different cement types have varying setting times and properties. Mixing can create unpredictable results and compromise performance.
Why is SRPC more expensive than regular cement?
SRPC requires special raw materials and controlled manufacturing processes. The limited C₃A content requires precise chemistry, increasing production costs.
When should I use rapid hardening cement?
Use RHPC when you need early strength for formwork removal, emergency repairs, or winter construction. It’s not necessary for standard applications.
How do I know if my soil contains sulphates?
Commission a soil analysis from a geotechnical laboratory. They’ll test sulphate content and recommend appropriate cement types based on exposure conditions.
What happens if I use the wrong cement type?
Wrong cement selection can lead to premature failure, reduced durability, or unnecessary costs. Severe cases might require structure replacement.
Is white cement as strong as grey cement?
Yes, white cement achieves similar strength to grey cement. The main difference is aesthetic – white cement costs more due to iron oxide removal.
How does cold weather affect cement performance?
Cold weather slows cement hydration, reducing early strength development. Use RHPC, heated mixing water, or insulated curing for winter construction.
Can I substitute one cement type for another?
Limited substitution is possible with engineering assessment. For example, PBFC can replace OPC in many applications, but SRPC substitution requires careful evaluation.
Conclusion: Making the Right Cement Choice for Your UK Project
Selecting the appropriate cement type forms the foundation of successful construction projects across the UK. Each cement type serves specific purposes, from OPC’s versatility for general construction to SRPC’s chemical resistance for harsh environments.
Your cement choice depends on three critical factors: environmental conditions, performance requirements, and project economics. Assess soil conditions, consider durability needs, and balance initial costs against long-term performance.
For most UK residential and commercial projects, OPC provides reliable, cost-effective performance. Choose PBFC for enhanced durability, PPC for mass concrete work, RHPC for urgent timelines, and SRPC for chemical exposure conditions.
Remember that proper storage, handling, and quality control remain essential regardless of cement type selection. Work with reputable suppliers, follow British Standards, and implement appropriate testing procedures to ensure optimal results.
The UK construction industry continues evolving toward more sustainable cement options. Consider environmental impact alongside technical performance when making your selection. PBFC and PPC offer reduced carbon footprints while maintaining excellent performance characteristics.
Success lies in matching cement properties to project requirements. Take time to assess your specific needs, consult technical specifications, and choose the cement type that delivers optimal performance for your UK construction project.
