High performance concrete
A concrete that delivers the highest performance.
Hanson Duracrete is a high performance concrete available from all Hanson Concrete plants across the UK. Ultimate strengths can exceed 100N/mm2, however it is the enhanced durability performance that is of most benefit.
Using silica fume and the latest admixture technology, Duracrete has a significantly reduced internal porosity compared with conventional high-strength concrete. This reduction improves the concrete’s ability to withstand ingress of usually harmful bodies such as chlorides. In addition to this, Duracrete has a much denser surface zone improving wear and abrasion over time.
Higher early-strength cycles can also be achieved typically from 3 to 7 days. For high-strength concrete within the first 48 hours, we would recommend our FastTrack range of concretes. This is due to the fact that it takes approximately 8 to 12 hours for sufficient Calcium Hydroxide to be liberated from the cement component to react with the silica fume and begin the full hydration process.
Duracrete’s increased durability and strength may be used as part of the initial design stage to minimise additional protective measures. This results in a possible reduction in reinforcement, and a possible reduction in cover to reinforcement. Plus, more slender cast elements such as columns which in turn provides more usable floor space within the build.
Where to use it
- Loading bays
- Scrap yards
- Warehouse floors
- Service yards
- Waste recycling yards
- Agricultural applications
- Coastal defence systems
- Foundry floors
- Hot material storage areas
- Better bond strength between paste and aggregates
- Better resistance of concrete to attack from sulphates
- Enhanced water tightness
- Early strength
- Early drying
- Underwater durability
- Withstands environmental extremes better
- Impact and abrasion resistance
Benefits subject to good concreting practice (placement, finishing and curing).
Hanson concrete can incorporate a proportion of Hanson Regen, (Ground Granulated Blast furnace Slag or 'GGBS'), which is a cement replacement material, helping to produce a product that generates a much lower level of CO2 emissions than ordinary cement.
