Roadstone has developed a range of high early strength concrete mixes through our research and development laboratory in Belgard, Dublin. Mixes specifically formulated through the selection of binders and admixtures that enhance early strength development while also retaining workability retention allow for fast track construction where early strength is essential.

Suitable for many different applications high early strength concrete mixes are often used for critical road repairs where road closures are kept to minimum to reduce traffic disruption. High early strength concrete mixes can be placed, pumped and finished just like conventional concrete.

Key Features & Benefits

• High early strength
• Allows for rapid re-instatement of repairs
• Minimises traffic disruptions
• Cost effective solution to challenging projects
• Can be placed and finished like conventional concrete

Applications

• Road repairs
• Yard slabs where early trafficking is required
• Bridge deck remediation
• Shut down situations in industrial facilities
• Marine environments

At what timescale can a target compressive strength be achieved?

Mixes are typically designed to achieve a compressive strength to meet the customer’s requirements. A requirement for a target compressive strength at 24 or 48 hours or 7 days is common. Requirements for strength to be achieved faster than 24 hours can be challenging as can achieving higher target compressive strengths at an earlier age. Further guidance should be sought from the Roadstone concrete technical department for more onerous requirements.
