Frequently Asked Questions

C30/C35 Concrete refers to high-strength structural concrete with characteristic compressive strengths of 30-35N/mm². C30 corresponds to the C30/37 strength class, while C35 corresponds to C35/45 in European standards. These grades provide exceptional load-bearing capacity for critical structural applications.

C30 Concrete (30N/mm²) is typically specified for heavy-duty structural applications such as commercial foundations and industrial floors. C35 Concrete (35N/mm²) is specified when even higher strength is required, such as for bridge structures, high-rise buildings, or structures exposed to aggressive environments.

Yes, for applications requiring C30/C35 Concrete, we strongly recommend working with a qualified structural engineer. These high-strength mixes are typically used for critical structural elements where precise calculations and detailed specifications are essential for structural integrity and safety.

C30/C35 Concrete typically requires carefully designed steel reinforcement based on structural calculations. This may include high-yield steel rebar, specialised reinforcement arrangements, or pre-stressing systems. Our technical team can collaborate with your structural engineer to ensure the concrete mix and reinforcement design work together optimally.

C30/C35 Concrete typically develops sufficient strength for cautious formwork removal within 24 hours under normal conditions. It achieves approximately 60-70% of its design strength after 7 days and continues to gain strength for up to 28 days to reach its full design strength of 30-35N/mm².

Yes, C30/C35 Concrete is well-suited for water-retaining structures due to its high strength and potential for low permeability. For such applications, we can incorporate water-reducing admixtures and design the mix for optimum impermeability. Additional waterproofing measures may be recommended depending on the specific requirements.

C30/C35 Concrete provides an excellent base for marine applications due to its high strength and density. For coastal or marine environments, we recommend additional specifications such as sulphate-resistant cement, specific aggregate types, and appropriate admixtures to enhance durability against chloride attack and salt exposure.

High-strength C30/C35 Concrete requires careful attention to placement techniques. This includes proper vibration to eliminate air voids, controlled pouring rates for heavily reinforced sections, and immediate implementation of appropriate curing methods. Our technical team can provide guidance on best practices for your specific project.
