Representing the concrete and aggregate capabilities of Adelaide Brighton, the Hy-Tec Group is comprised of Hy-Tec Industries Pty Ltd (New South Wales), Aus10 Rhyolite Pty Ltd (Austen Quarry), Hy-Tec Industries (Queensland) Pty Ltd and Hy-Tec Industries (Victoria) Pty Ltd. Hy-Tec supplies commercial, industrial, civil and residential construction companies across the Sunshine Coast in Queensland, Sydney, Melbourne and northern New South Wales with over one million cubic meters per annum of quality premixed concrete, aggregates and sands.

Included in this service are a number of innovative alternative cementitious materials which utilise such materials as fly ash, ground granulated blast furnace slag, bottom ash, air cooled slag aggregates, recycled water and concrete aggregates as well as alternative raw materials. The use of these materials – which are sourced from local steel plants and Hy-Tec’s own quarries – help to decrease the environmental impact of traditional concrete materials and processes while assisting Hy-Tec’s clients to improve their own Green Star Ratings and sustainable design principles.

Recently Hy-Tec put these materials to work on The Ark, a twenty one storey commercial building integrated into North Sydney’s heritage precinct. In order to conform to the GBCA Mat-5 Green Star Rating, the building incorporated numerous sustainable features and materials. In particular, Hy-Tec supplied industrial bi-products including fly ash, ground granulate blast furnace slag and air cooled slag aggregates to ensure a high strength, and 80 and 100 MPa concrete and post-tensioned concrete for the construction of columns and suspended slab designs, respectively.

The development of such advanced products requires dedication to quality outcomes and personal service. To ensure that these innovations are best implemented, Hy-Tec’s staff works directly with its clients from the tender stage through to supply and post completion of a project. Additionally, clients are able to access Hy-Tec’s allocators directly for increased access to information regarding potential or planned deliveries.

The staff structure is unique in that it leans preferentially toward a flat, open culture whereby members of the staff are encouraged to work together on equal ground to get the project completed with optimal success. In keeping with this, Hy-Tec aims for the minimisation of corporate policy, choosing instead to focus on quality outcomes through hard work and high levels of skill. Just as environmental conservancy is of utmost importance to Hy-Tec, so too is its commitment to the safety and welfare of its staff, contractors and customers. In recognition of its extra efforts in these two areas, Hy-Tec was awarded the 2009 Cement, Concrete & Aggregates Australia (CCAA) NSW environment and safety awards.

Governed by the comprehensive sustainability policy of Adelaide Brighton Ltd, the issue in general is a key focus for Hy-Tec, which has implemented conservancy initiatives across a broad spectrum of business operations which maximise natural resources, and conserve products. For one, Hy-Tec employs life cycle management techniques such as the recycling of settled sludge from truck wash bays through aggregate quarries as rubble, and using recycled aggregates from crush waste concrete in the development of low-strength mixes. Furthermore, Hy-Tec captures and reuses waste water for its concrete manufacturing process and exports excess concrete waste to external manufacturing facilities so that they may be utilised elsewhere in the construction industry.

Hy-Tec operates its own laboratories, established in New South Wales and Queensland and with additional access to external testing facilities, adding to its already broad capabilities. In addition, it is sometimes possible for clients to arrange for on-site testing through Hy-Tec, an option which helps to ensure that each client receives continuous high quality outcomes throughout every project. The laboratories are all NATA accredited as are the staff who facilitate testing and technical support. Hy-Tec utilises a Quality Management System which complies with the requirements of ISO 9001:2008.

Hy-Tec’s standard products consist of normal class concrete 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 and available in 10, 14 and 20 mm aggregate sizes. Its special class concrete includes high strength 65 MPa to 100 MPa with options in design slump between 140 and 200 mm and available in 10, 14 and 20 mm aggregate sizes (20mm only available for 65 MPa); block fill designed as a 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 and 230 mm; and shotcrete, 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.

Also available are associated products including steel reinforcement products to provide tensile strength for in-situ concrete, steel and polypropylene fibres, set-retarding admixtures to slow concrete setting, super-plasticisers which increase the fluidity of concrete for placement of concrete in difficult formed areas, and colour oxides for decorative purposes.

Hy-Tec’s ability to use assorted coloured aggregates in combination to create matching effects of pre-existing architectural features can be seen in its work completed recently for a local government project in Queensland. Hy-Tec supplied “˜Dig It Landscapes’ with 560 cubic metres of concrete to match existing concrete and terrazzo styled paving in the Nambour Town Square. A mass concrete structure and associated walls were polished or sand-blasted, with the polished sections made to match polished paving. Hy-Tec incorporated local materials and innovative colouring techniques on this project, ultimately decreasing the costs and greenhouse gas emissions in cement production by 30%.

It is through this class of flexibility and dedication to quality and standards that Hy-Tec has continued to expand into accepting larger projects and entering more diverse markets. One such area which Hy-Tec is working to increase its exposure to in the near future is that of the private or residential market. Offering a beautiful array of decorative concrete products as well as the option for clients to personally design a unique mix of exposed, coloured or polished concrete, Hy-Tec is clearly prepared for this next development and will certainly impress homeowners and developers alike with its innovative green products.

Home Automation

Call it ‘domotics,’ and you are likely to receive a blank stare, but refer to it as ‘smart home’ or ‘home automation,’ and you will get a nod of acknowledgement. For the past few years, consumers have heard the word ‘smart’ attached to countless products and services, from food and drink to snacks like popcorn and mobile phones, which no one seems to refer to as a ‘cellphone’ anymore. Yet what, exactly, constitutes ‘smart’?
