Normal Class concrete

Products ranging from 20 to 50 MPa compressive strength at 28 days with a design slump that has a point of acceptance from 20 to 120 mm are available in both 10 mm, 14 mm and 20 mm aggregate sizes.

20 MPa and 25 MPa

Commonly used for house slabs, driveways, footings and footpaths.

Residential slabs and footings

A default slump of 100 mm has been adopted by the premix concrete industry to reduce the uncontrolled addition of water on site and make placing and compacting of concrete easier for concreters.

32 MPa, 40 MPa, 50 MPa

Higher strength is commonly used for concrete that will experience greater loads and traffic. This may be specified by engineers or builders to suit the load requirements which the concrete must support during its life.

Special Class Concrete

High strength 65 MPa, 80 MPa, 100 MPa

Commonly used for projects requiring high strength concrete with options in design slump between 140 and 200 mm. 65 MPa concrete is available in 10 mm, 14 mm and 20 mm aggregate sizes while 80 and 100 MPa are only available in 10 mm and 14 mm aggregate size. High strength concrete is usually specified by engineers in applications such as high rise buildings.

Block fill

7 mm and 10 mm flowable product ranging from 20 to 40 MPa compressive strength at 28 days with options in design slump between 140 mm and 230 mm. Block fill product has been designed to pump through a two inch rubber hose line making it easier when placing into block work walls.


Shotcrete is designed as a 7 mm and 10 mm aggregate sized sprayed product ranging from 20 to 50 MPa compressive strength at 28 days, with a design slump of 60 mm. Ideal for spraying pool walls, embankments, structural and retaining walls.


Decorative Concrete

Exposed aggregate display, corner of Commercial and Fishermans Road, Maroochydore, QLD

Exposed aggregate

This popular mix has the ability to be adapted to suit your decorative requirements through the use of our extensive range of colourful decorative aggregates. These can be used to create different combinations, producing a myriad of effects that can be matched to architectural features or themes. This product is often complimented with the use of grey or off white cement and colour oxides.

Polished concrete

Being very similar to exposed aggregate in colour and materials used, the surface is ground down to expose the aggregate which is then polished and sealed to give a vibrant smooth finish.


Coloured concrete

Our coloured concrete range has been a popular choice in housing, and many other applications.  The colour of the concrete comes from metal oxides which are added to the concrete mix to produce a desired full depth concrete colour. Ideally this product is used in applications that require colour that matches specific areas or features of a project.

low carbon Concrete

Over 15 years ago, Adbri began innovating our products, using cement substitutes in our mixes. Through rigorous testing and product development, we developed the Futurecrete® range of lower embodied carbon concrete, by incorporating cement substitutes to reduce the embodied carbon in concrete. Futurecrete® Ultra results in further carbon reductions by substituting a higher percentage of cement with supplementary cementitious materials (SCMs). Manufactured in accordance with AS1379 and AS3600, our Futurecrete® concretes are suitable for a range of applications without compromising on strength and durability.

Associated Products


HY-TEC is a reseller of steel reinforcement products. Steel reinforcement is required to provide tensile strength to the in-situ concrete.


HY-TEC can supply steel and polypropylene fibres upon specification. For more information please contact your Account Manager.


Colour oxides (bags) are added to concrete at the time of batching. Oxides are extensively used in decorative concrete applications such as coloured concrete, exposed aggregate and polished concrete.

Accelerators / Retarders

Set-retarding admixtures slow the setting of concrete. They are most commonly used in summer, during warm to hot weather conditions and can also be utilised when a concrete mix is to be transported long distances. Set-accelerating admixtures are typically used in the cold winter months to shorten the set time of concrete.


Superplasticisers are chemicals with new polymer technology that increase the fluidity of the concrete making it easier to place. Higher strengths can be achieved (e.g. 65 MPa to 100 MPa concrete) as well as allowing for the placement of concrete in difficult formed areas and where reinforcement is congested. It should be noted that the use of superplasticisers does not remove the need for proper compaction.
