Building Recovery Forecast

The downturn in the Australian building sector will bottom out this financial year with Queensland forecast to play a major role in the recovery.

Leading building market analyst and economic forecaster BIS Oxford Economics found national building commencements contracted by about 12 per cent in 2018-19 to AUD$109.8 billion from the record peak reached in the previous financial year… with an 8 per cent decline forecast for 2019-20 with the fall in residential building outweighing growth expected in the non-residential sector…

BIS Oxford Economic managing director Robert Mellor said “strong population growth, a rising national dwelling stock deficiency and housing stimulus (are set to boost) total building activity (which) is anticipated to climb near its previous peak over the coming five years and Queensland and Western Australia are well-positioned to lead the next residential upturn ahead of NSW and Victoria.”  

The report found that undersupply will drive the residential market over the four years, with dwelling commencements forecast to rise a cumulative 55 per cent to a peak of 236,650 in 2023-24. Non-residential building commencements…will hold at a record base of around $47 billion per annum through to 2022-23.

Mr. Mellor said NSW and Queensland will lift to record levels in non-residential building over the next two years.

Cesco Australia limited is proud to release to the Australian market our NEW 7.6m3 WEIGHT$AVER mixer.

After consulting with our customers and during that process receiving constructive input, finding out what your exact needs are and then focusing on just how we would achieve a successful outcome for all. A continuous improvement project was initiated approximately 18 months ago. The Continuous Improvement Team at Cesco Australia was formed and tasked with 3 main requests for our customers – “Lighter” “Lower” and more “Durable” hence the industry first WEIGHT$AVER mixer was developed.  This project has been a joint collaboration between Cesco Australia, its customers and suppliers all working closely together to maximise the benefit to the industry and you the end user.

The results have seen the mixer weight reduced by a massive 350 kg approximately 10% on our standard 7.5m3 load master mixer series which equates to .15m3 extra payload.  In the past, most weight reduction results achieved have come at a price – those being through quality, structural integrity and/or performance longevity. The WEIGHT$AVER has been developed with all these obstacles and challenges in mind and is proving itself in the field.

THE HYDRAULIC SYSTEM 

Essential to the weight saving and efficiency gain of the WEIGHT$AVER Cesco Australia has partnered with ZF Australia to introduce the new ZF CML range of gearboxes into the Australian Market after extensive trials in Europe and America.

The CML range of Gear boxes are:

• Smaller
• Lighter
• Shorter
• Quieter
• More efficient
• Tougher

Another benefit of the CML range of gear boxes is their unique gearbox ratio coupled with a larger pump, this only requires the truck to Rev at 1400 PRM to achieve the 16 to 18 barrel RPM to meet the Australian Standard. This outcome of reduced revving not only preserves the hydraulics, mixer drive gearbox and truck engine, it represents a major benefit to the operator delivering a 22% efficiency saving when loading and slumping.

THE BARREL AND BLADES 

How did we increase the barrel and blade componentry life, yet make it lighter. The Barrel skin along with Cesco Australia’s unique pressed blades system, are now developed and formed from lighter, harder wearing steel, increasing lifetime and reducing weight. With the SSAB designed and Engineered steel Hardox, and a sizeable investment by Cesco Australia in a large capacity press, heavy duty dies, associated equipment required to developed and incorporated this toughened steel and exhausted welding tests all to complement our barrel design. The combination of all this has allowed Cesco Australia achieve an increase in your barrel life, at the same time keeping our structural integrity and significantly reducing our weight.  Using the only joggle join system in Australia gives Cesco Australia the competitive advantage, using the thinner Hardox steel without comprising the structural reliability customers have come to expect from the unique Cesco design. The joggle design allows the midsection skin to overlap on the inside of both the cones, allowing for doubling on barrel skin at the joins and also protecting against wear caused from the breaking down of metallurgy properties of the Toughened steel as a result of the welding process. The unique sub arc welding process used in this stage of barrel manufacture complements the whole process.  It is estimated that the toughened, harder-wearing steel, although 1mm thinner than steel used currently, will have at least a 30% better life than current mixer barrels being used in the market place.

THE FRAME 

The WEIGHT$AVER mixer is also lower and more durable, our Engineering team have achieved this has by reducing the RHS sizing from 100mm x 100mm RHS to 100mm x 75mm RHS. A height reduction is 25mm, and the durability has been increased after a series of FEA tests proved by reducing from 100mm to 75mm was acceptable, but would require the use of a higher grade of steel than we are currently using. FEA was complete and units have been on trial for over 6 months now with no reported issues.

Cesco’s Mission Statement has been the driving point for this innovation.

The market innovative LowRider Frameless Mixer from Cesco mounted on the sturdy platform of the Mack Metroliner.

The LowRider gives the astute Agi operator unique safety & operating advances as well as a ROI that no other mixer can provide!

Here’s what Dean Kumnick, Sales Manager of South Qld. Trucks had to say about the Mack Metroliner and the LowRider combinationin a recent post ….

Economix has been supplying concrete to commercial, industrial and residential customers in Victoria for over 30 years. Concrete is not the only game in town for this diverse company – also featuring building supplies, precast and decorative concrete.

To increase their capability for project, bigger pours, Economix came to Cesco to add the Big Daddy Trailer Mixer to their fleet operations.

Form of carbon incorporated into concrete created stronger, more water-resistant composite material that could reduce emissions.

The novel “supermaterial” graphene could hold the key to making one of the oldest building materials greener, new scientific research suggests.

Graphene has been incorporated into traditional concrete production by scientists at the University of Exeter, developing a composite material which is more than twice as strong and four times more water-resistant than existing concretes.

Unlike previous attempts to use nanotechnology in concrete, which have focused on modifying the existing components of cement, the new technique allows a layer of graphene to be suspended in water.

The method produces a high yield of concrete without defects, which can be used in conjunction with modern manufacturing techniques and could be scaled up, the researchers believe, at a relatively low cost.

The composite could be used directly on building sites, enabling the construction of strong and durable buildings using less concrete and reducing greenhouse gas emissions. Using graphene meant the researchers were able to roughly halve the amount of materials used to make concrete.

Its water resistance makes it suitable for construction in areas that are hard to reach for maintenance, while the strength of the composite will make buildings more resilient to future shocks and strains, researchers say. In addition, the technique could be copied in incorporating other nanomaterials into concrete construction in the future, which could pave the way to further innovations in the industry.

Monica Craciun, professor of nanoscience at the University of Exeter’s engineering department, said: “Our cities face a growing pressure from global challenges on pollution, sustainable urbanisation and resilience to catastrophic natural events. This new composite material is an absolute game-changer in terms of reinforcing traditional concrete to meet these needs.”

Graphene is a form of carbon first reliably produced at the University of Manchester by researchers in 2004, work which led to two Nobel prizes. It is made up of a single layer of carbon atoms in a hexagonal lattice. Its structure gives it important physical qualities, including efficient conductance of heat and electricity and unusual strength.

Concrete has been used as a building material since the Romans, some of whose concrete structures still stand today. It is the commonest building material, along with steel, but greenhouse gas emissions from concrete and cement-making remain stubbornly high, in part because of the energy used in their creation but also because the chemical processes required involve the break-up of limestone and release of carbon dioxide.

Cement-making accounts for 6% of global carbon emissions, and manufacturers must make sharp reductions if the Paris climate goals are to be met, according to the Carbon Disclosure Project, in a recent study.

The University of Exeter research, in a paper entitled Ultrahigh Performance nanoengineered Graphene-Concrete Composites for Multifunctional Applications, is published in the journal Advanced Functional Materials, and was funded by the UK’s Engineering and Physical Sciences Research Council.

The samples of the composite tested so far all come up to British and European standards, so getting the composite material into use should be possible. Dimitar Dimov, lead author of the study, said: “Finding greener ways to build is a crucial step forward in reducing carbon emissions around the world. This is a crucial step in the right direction to make a more sustainable construction industry.”

Mr Electric of Newcastle became involved in the following retrofit of a new agitator into a 2003 Mack concrete truck purely by accident.

Whilst attending to contracted work at Newcastle Ready Mix Pty Ltd, I was brought into a conversation regarding a broken concrete truck and asked if I might look at it and to see if I might have a solution. (more…)

The Start of the Project

The location is Bamaga Australia, one of Australia’s last frontiers. We are connected to the outside world by internet and phone. There is what you might call a road to Cairns. Our nearest McDonald’s store is 1000klm south on a wild 600klm long red dirt track. All our supplies arrive once a week on a ship or by air.

One of the major drivers for development of Cesco’s ground-breaking, new Frameless Low Rider mixer unit has been to reduce the risk of roll-overs, in the design of a safer, more stable and uniquely-mounted agi unit. In the November issue of Owner Driver, Steve Brooks in his article ‘Turn for the Better’ reports on the significant benefits & advances that the Frameless has bought to Boral.

There have been a number of advances in new concrete technology in the past ten years. There have been advancements made in almost all areas of concrete production including materials, recycling, mixture proportioning, durability, and environmental quality. However, many of these innovations have not been adopted by the concrete industry or concrete users / buyers. There is always some resistance to change and it is usually based on cost considerations and lack of familiarity with the new technology.

The latest new concrete technology is beginning to gain acceptance in the industry. Some of the more interesting new concretes are called high performance concrete (HPC), ultra high performance concrete, and geopolymer concrete. They have significant advantages and little or no disadvantages when compared to standard concrete in use today.

High performance concrete usually contains recycled materials and thereby reduces the need to dispose of these materials. Some of these materials include fly ash (waste by-product from coal burning), ground granulated blast furnace slag, and silica fume. But perhaps the biggest benefit of using some of these other materials is the reduction in the need to use cement, also commonly referred to as Portland cement. The reduction in the production and use of cement will have many beneficial effects. These benefits will include a reduction in the creation of carbon dioxide emissions and a reduction in energy consumption, both of which will improve the global warming situation. It is estimated that the production of cement worldwide contributes five to eight percent of global carbon dioxide emissions. In addition, the use of fly ash and furnace slag is usually cheaper than cement and they have properties that improve the quality of the final concrete.

Today’s new concrete technology has produced new types of concrete that have live spans measured in the hundreds of years rather than decades. The use of fly ash and other by-product materials will save many hundreds of thousands of acres of land that would have been used for disposal purposes. Fly ash and other by-products from burning coal, are some of the most abundant industrial waste by-products on the planet. The elimination of burial sites for these waste by-products will translate into less risk of contamination of surface and underground water supplies. When compared to standard concrete the new concretes have better corrosion resistance, equal or higher compressive and tensile strengths, higher fire resistance, and rapid curing and strength gain. In addition, the production and life cycle of these new concretes will reduce greenhouse gas emissions by as much as 90%.

BSI is a new concrete technology that has a much higher tensile and flexural (bending) strength than standard concrete. It is a fiber-reinforced concrete that is combined with premixed dry components. It is much denser than standard concrete and structures built with it will need far less new concrete, perhaps as much as 80% less. The high density gives BSI concrete other properties such as extremely high resistance to corrosion from chemicals. The higher strength of BSI eliminates the need for placement of steel rebar in structural designs. BSI, or some variation with metallic fibers and/or superplasticizers, will be used to build some structural elements less than an inch thick. Overall, structures built with BSI will have much greater life spans and will require far less maintenance.

Ductal is another new concrete technology that is denser than BSI. Ductal uses steel or organic fibers to create a concrete that is stronger than BSI. Interestingly, the ancient Romans used horse hair in their concrete to improve its strength. Ductal is being tested for use in earthquake resistant structures, bridges, tunnels, and nuclear containment structures. Although it is more expensive than traditional concrete there are a number of cost savings that will make it price competitive. Among these cost savings are no steel rebar is needed, less material is needed with less related labor and equipment costs, and structures are thinner with less weight and require smaller foundations. In addition, both BSI and Ductal have low maintenance costs because of their very low porosity and are very resistant to penetration by water or chemicals. They are both resistant to salt water which is very corrosive and damaging to today’s bridges and roadways.
