Concrete mix design optimisation

Halcrow's materials engineers are involved with the development of a range of high performance mixes.

These include:

• grouts
• foamed and insulating concretes
• high-strength lightweight concrete
• self-levelling underwater concrete
• recycled-aggregate concrete
• high-durability structural concrete for extreme conditions
• fire-resistant concrete for tunnels

We bring to this work:

• the expertise of our widely-experienced staff
• immense practical experience of construction materials in many parts of the world
• state-of-the-art software for development of mixes taking into account the grading of available aggregates
• an understanding of the production processes and the properties of the natural materials
