Premium Grade GEN 2 Concrete - C16/20 Strength

GEN 2 Concrete (C16/20) has a lower strength classification than GEN 3 (C20/25). While GEN 2 is suitable for most structural applications, GEN 3 is typically specified for more demanding structural elements or where additional load-bearing capacity is required.

Yes, GEN 2 Concrete is ideal for many commercial applications including floors, footings, and areas with moderate traffic. Its C16/20 strength classification provides the necessary durability and load-bearing capacity for most commercial requirements.

Most structural applications of GEN 2 Concrete benefit from appropriate reinforcement. Steel mesh, rebar, or fibre reinforcement can be incorporated to enhance tensile strength and crack resistance. Our technical team can advise on the most suitable reinforcement strategy for your project.

The required thickness depends on the specific application and expected loads. For domestic driveways, 100-150mm is typically sufficient. Commercial floors may require 150-200mm or more. Our technical team can provide specific recommendations based on your project requirements.

While GEN 2 Concrete typically develops sufficient strength for form removal within 24-48 hours, it continues to gain strength for up to 28 days. The concrete achieves approximately 70% of its design strength within 7 days under normal conditions.

Yes, our GEN 2 Concrete mix is designed with excellent workability characteristics that make it suitable for pumping. This can be particularly beneficial for sites with limited access or where concrete needs to be placed at height or distance from the delivery vehicle.

GEN 2 Concrete can be placed in cold weather, though special precautions may be necessary when temperatures approach freezing. We can provide cold weather admixtures when required, and our technical team can advise on best practices for winter concrete placement.
