Special Class Concrete

Special Class Concrete

Entire Concrete has a range of Special Class Concrete mixes designed to meet the strictest engineering specifications including high flexural strength, low-shrinkage, marine, waterproof and high tensile strength concrete.

We pride ourselves on sourcing premium aggregates, additives and cements that deliver a high-strength, high-quality ready mix concrete product.

Our high early and long-term strength special class concrete is ideal for pre-cast applications and offers superior strength, workability and durability.

Early Strength Concrete – Precast panels
Generally specified at slumps of 140mm+ to achieve a high quality off-form finish, precast concrete can be designed to achieve early age strength to meet specific lifting requirements.

 Early Strength Concrete – Post Tensioned Concrete: Generally used in suspended slab work to meet early age strength requirements. The concrete is generally ordered at 22MPa @ 4 days or 5 days.

Flexural Properties: Concrete can be specified with a flexural requirement as well as a compressive strength. Most often specified for high load, high wear applications.

Fibre Reinforced Concrete: Steel fibres or poly fibres can be added to the concrete mix design to assist with minimising early age concrete cracking and to reduce the permeability of the concrete.

 No Fines Concrete: Made for drainage applications the concrete is designed without fine aggregates to make the concrete permeable so fluids can flow through the concrete.

 Flowable Concretes: Includes concrete designed for applications such as Piling, Stabilised Thermal Backfill for encasing power cables, filling Masonry blocks, Tremie work and structural concrete for bridge work. The concrete is usually designed to be super flowable through the addition of specialised super-plasticising admixtures generally in combination with low water binder ratios to achieve high early compressive strength and good off form finish characteristics.
