DYNAMax®: HIGH-PERFORMANCE CONCRETE

The Ultimate High-Performance Concrete (HPC) for Demanding Structures

DYNAMax® is a High-Performance Concrete (HPC) engineered to meet special combinations of strength, durability, and stiffness requirements that cannot be achieved with conventional concrete. Through careful selection and proportioning of its constituents, DYNAMax delivers superior concrete stiffness, outstanding durability, and the ability to "build far more, with less" material. This makes it the ultimate solution for complex, tightly-toleranced structures and highly exposed environments.

Benefits

Structural Efficiency

Superior strength and stiffness allow for sleeker buildings and highly rigid concrete cores, often reducing the overall volume of concrete required.

Outstanding Durability

Offers highly chemical resistant properties, making it essential for structures in aggressive environments like marine, coastal, and heavily trafficked areas.

Optimised Placement

Exhibits excellent pumping properties and high workability, ensuring it is readily placed by all conventional methods while maintaining a working life of up to 90 minutes.

Why DYNAMax

DYNAMax is an expertly engineered product where the main features—strength, durability, and stiffness—are meticulously controlled for uniformity. The ability to achieve higher strengths at early ages, and a superior Modulus of Elasticity, is crucial for complex construction projects where column sizes must be minimised or tight deflection tolerances are mandatory.

The DYNAMax range includes specialised variations like DYNAMax^XD and DYNAMax^XR (Extreme Resistance), allowing the product to be tailored for specific environmental challenges. Furthermore, DYNAMax is a circular product that can be recycled into crushed concrete aggregate at the end of its long service life, supporting sustainable construction practices. A pre-pour meeting is strongly recommended before use to coordinate delivery and placement logistics.

Applications

High-Rise & Tight Tolerance Buildings: Essential for walls, columns, and rigid concrete cores where concrete stiffness is paramount and size must be minimised.
Infrastructure: Ideal for marine, flood, and coastal sea defences due to its outstanding durability and highly chemical resistant properties.
Car Parks & Industrial Floors: Used in concrete frame car parks and heavily trafficked concrete floors that require maximum wear resistance.
Complex Structures: Suitable for tunnel linings and flat suspended concrete floors where strength and reduced material volume are key.
