Diving into a pool from a few feet up allows you to enter the water smoothly and painlessly, but jumping from a bridge can lead to a fatal impact. The water is the same in each case, so why is the effect of hitting its surface so different?

The findings could ultimately help explain phenomena as varied as the breakdown of concrete under sudden stress and the effects of corrosion on various metal surfaces. More...

Can concrete conquer air pollution?5 Feb 2018

In 2014, the Stony Brook researchers showed that powdered concrete can react with nitrogen oxides, often called NOx. These pollutants contribute to the formation of smog, a type of lung-choking pollution. NOx also can play a role in turning rainfall acidic. This can damage crops, buildings and more. But cement contains calcium compounds. And they will react with NOx, pulling them out of the air, Ramakrishnan and a colleague showed.

MIT students fortify concrete by adding recycled plastic
MIT students fortify concrete by adding recycled plastic19 Dec 2017

Discarded plastic bottles could one day be used to build stronger, more flexible concrete structures, from sidewalks and street barriers, to buildings and bridges, according to a new study.
MIT undergraduate students have found that, by exposing plastic flakes to small, harmless doses of gamma radiation, then pulverizing the flakes into a fine powder, they can mix the irradiated plastic with cement paste and fly ash to produce concrete that is up to 15 percent stronger than conventional concrete.
“There is a huge amount of plastic that is landfilled every year,” says Michael Short, an assistant professor in MIT’s Department of Nuclear Science and Engineering. “Our technology takes plastic out of the landfill, locks it up in concrete, and also uses less cement to make the concrete, which makes fewer carbon dioxide emissions. This has the potential to pull plastic landfill waste out of the landfill and into buildings, where it could actually help to make them stronger.”

Many pedestrian bridges have experienced dramatic vibrations and wobbling when crowds have tried to cross them, e.g. the London Millennium Bridge began to sway on its opening day in 2000 and had to be closed while the Squibb Park Bridge in NY bounced sideways as pedestrians crossed in 2014, not reopening until this year. This movement could be reduced by using biomechanically inspired models of pedestrian response to bridge motion and a mathematical formula to estimate the critical crowd size at which bridge wobbling begins, according to a study by Georgia State University.

Project Profile - Prefabricated Concrete for the Song School, J Woodside Consulting and SA Precast23 Nov 2017

The Institute is very pleased to introduce our final project profile, and winner of both the Commercial Buildings project category and the Kevin Cavanagh Trophy for outstanding excellence in concrete – Prefabricated Concrete for the Song School by J Woodside Consulting and SA Precast!


















The Song School is a two-storey concrete building, designed by Palassis Architects for the choirs of St George’s Cathedral and the Anglican Diocese of Perth. The building is partly underground to minimise the footprint and maintain existing sightlines.


















The lower floor included prefabricated concrete curved beams internally together with an exposed prefabricated concrete external wall at the Eastern end, with vertical slots and glazed to provide light into the lower area.


















From the lower level, a series of U-shaped prefabricated columns support a series of prefabricated concrete vaulted arches at the first floor which forms a colonnade with access from the lower level to the upper level. On top of the vaulted units, there are two curved and sloping prefabricated concrete spires.


















The prefabricated concrete elements for the Song School at the St George’s Cathedral are made with a white concrete with an off form sandblasted finish. They represent excellence in prefabricated concrete and ability to achieve the shape and form that the architect has specified.


















SA Precast and J Woodside Consulting combined to produce a workable solution to the architect’s concept and in its final shape and form and erection has been admired by all involved.





































As the documentation had to be significantly changed there was considerable input into details and connections to achieve a workable solution. This also included bracing of the precast elements on the site.


















There is no doubt this project has pushed the boundaries of precast concrete, and we look forward to seeing more projects from SA Precast and J Woodside Consulting!

Project Profile - Wandoo B Concrete Gravity Structure, GHD & Vermilion Oil and Gas Australia14 Nov 2017

This year we received a range of technology and innovation projects entered into our Awards for Excellence Program, each pushing the boundaries of concrete. The 13 project entries that were entered demonstrated innovation in its finest form - exploring theory, materials, processes, systems and technology that has the capability to transform the industry.














There could only be one Medallion for Excellence Winner of this category, and the Institute was very pleased to award this to GHD and Vermilion Oil and Gas Australia for their innovative project - Condition Investigation, Remaining Life Assessment and Inspection Maintenance and Repair Plan for Wandoo B Concrete Gravity Structure.















Vermilion Oil & Gas oil production in the Western Australian North west shelf, 75 kms offshore from Karratha, relies on the Wandoo B Concrete Gravity Structure (CGS) to structurally support its oil facilities and provide oil storage.















The CGS original operational life was 20 years (from 1997) and an extension of 20 years was required. The exposure condition is aggressive offshore marine. Inspection and testing of concrete was challenging and key constraints for an operational offshore oil platform above water included limited accessibility to surfaces, maintaining site operations during survey works, working at heights and over water with safety as a priority. Inspections below water were conducted using Remotely Operated Vehicles (ROV), where sea level tides and currents provided significant challenges during inspection.













GHD was engaged as the concrete engineering consultant to complete the CGS condition investigation and remaining life assessment including provision of an inspection, maintenance and repair (IMR) plan. Third party verification was by Lloyds Register. The CGS has seabed oil storage caissons 115 m long, 70 m wide and 17 m high and four shafts 10 m internal diameter to 69 m high. Design uses reinforcement and prestress tendons. Concrete was grade 50 MPa with 65% blast furnace slag.















The remaining life assessment determined a 20 year life extension can be achieved. A service life of 60+ years can reasonably be achieved with specific life primarily dependent on atmospheric concrete chloride ingress risk and following the IMR Plan first-time developed for the Wandoo B CGS. The judges noted that this innovation and technology was ground-breaking, and could have massive implications worldwide for the industry.

The Institute is already looking forward to the technology and innovation projects entered in our 2019 program!

Project Profile - The Adelaide Convention Centre Plenary Building, Aurecon7 Nov 2017

Repair and rehabilitation of projects is critical to extending a structures service and design life, and provides the perfect opportunity to implement creative solutions. Our winner of the Medallion for Excellence in the Repair and Rehabilitation category - Aurecon, have creatively implemented solutions to reduce cost and increase efficiency without compromising quality.




















The new Adelaide Convention Centre Plenary building replaces the original plenary building with a larger, heavier, highly functional and adaptable state-of-the-art facility. Similar to the original plenary, the new building is atop the existing northern car park, rail corridor and plaza buildings that were retained and provide the new construction structural support. This involved both re-rating and strengthening the existing concrete structure and working with the architect to position the new building where the greatest structural capacity existed.
















To achieve this the Aurecon team undertook detailed inspection, testing, analysis, calculation and creative design to increase and manipulate the capacity of the existing concrete structures and foundations to suit the new facility, minimising the substructure works and avoiding new piling all together. The strengthening works included new in ground foundations and tie beams to better mobilise the existing piles; column strengthening to increase the vertical load capacity new insitu concrete cores and shear walls to carry the heavier structure under more stringent design codes.
















These strengthening works were completed without compromising car park capacity and rail clearance envelopes. The team worked collaboratively with the Architect and Client to evolve the architectural form of the building to respond to the existing structural constraints.











































The judges noted that this was an extremely clever project, and the final design achieved savings in critical project budget and programme, and successfully diverted investment from the substructure into the functionality and aesthetic of the superstructure.















Thanks to Aurecon for entering this excellent project into our Awards for Excellence program - We look forward to viewing what projects are on the horizon for Aurecon!

Project Profile - Jubilee Bridge, ARUP2 Nov 2017

Our 2017 Awards for Excellence program received 51 project entries, an incredible 15 of these were infrastructure projects. However, only one project could win the Medallion for Excellence in this particular category – Jubilee Bridge, by ARUP.















Measuring 220m in length, 6 metres in width, 3,000 tonnes in weight, the curvilinear Jubilee Bridge forms the final link of the barrier-free 3.5km Marina Bay waterfront loop. With its timely completion to celebrate Singapore’s 50th year of independence, the bridge, part of an 8km heritage trail around the Civic District, has become linked to the nation’s history.















Set in a busy maritime environment, the design team was challenged to achieve the aspiration of a simple, elegant and slender bridge form, with careful consideration of safety and minimal disruption to the public during construction. Connecting two famed landmarks - the Esplanade Theatre and the Merlion - the Jubilee Bridge took reference from Merlion’s water spray and was designed to counterpoise the more elaborate Helix Bridge across the bay. Offering an unobstructed panoramic view of Singapore’s magnificent skyline, the Jubilee Bridge has since added to the city’s vibrancy and aided its aspiration of becoming a walkable city.














The profile of the Jubilee Bridge is curved in plan, elevation and section. This presented a range of challenges for both the design and construction of the bridge. The multi-curved nature provides a unique bridge profile not commonly noted, nor manufactured easily by precasting. The slender depth of the bridge at mid-span is also an unorthodox feature made possible by the use of high-strength concrete and a field of post-tensioned tendons.



















The judges noted that it was exceptionally well executed, especially as there were challenges involved in the casting of in-situ concrete to match precast segments. A beautiful looking bridge.















We’re already looking forward to what the future holds for consulting engineers, ARUP!

Project Profile - Manly House, Partridge Structural31 Oct 2017

The Concrete Institute of Australia is very pleased to be highlighting our Medallion Winners that were recently awarded at Concrete 2017. We will begin by exploring our Residential Projects Winner – Manly House, entered by Partridge Structural.

This beachfront residential project in Manly, NSW, involved the construction of an all-new, freestanding three-storey house. The house construction consists of suspended, conventionally reinforced concrete slabs at all levels, supported on a combination of loadbearing masonry (both brick and core-filled concrete block), structural steel columns, and reinforced concrete blade walls.





Engineering features and challenges evident in the project are exposed Class 1 off-form concrete finishes; an aggressive exposure environment just 40m from breaking surf; large cantilevers with thin profiles; slender supports; large open spans, highly bespoke concrete detailing; highly stressed torsion beams; suspended beams and slabs with large rebates and recesses for architectural features; and an exceptional curved concrete shell "column" that was matched to adjacent curved brickwork shells and actually worked as a strut-and-tie beam.

Every aspect of the concrete's design, detailing, and actual construction - whether a beam, a slab, or a column - had the concrete working near to its ultimate capacity, with very little margin or redundancy. It is also a project where the concrete is the "hero of the dish" being fully exposed and on display.

The judges commented in particular that the engineering involved in the cast in-situ, vertical, thin curved elements was extremely difficult and then to be constructed with off white cement to such a high-quality finish was exceptional.




We look forward to viewing upcoming projects completed by Partridge Structural!
