Short-pulse laser cleaning for Australian heritage conservation. Conserving heritage objects is a demanding discipline, requiring a suite of techniques for different problems. Overseas, laser cleaning using long pulse techniques leaves microscopic damage as discrete chunks of material are removed, and is unsuitable for many materials. We have developed a short pulse laser process which can remove material molecule-by-molecule in a controlled fashion, and which can be readily halted once the fi ....Short-pulse laser cleaning for Australian heritage conservation. Conserving heritage objects is a demanding discipline, requiring a suite of techniques for different problems. Overseas, laser cleaning using long pulse techniques leaves microscopic damage as discrete chunks of material are removed, and is unsuitable for many materials. We have developed a short pulse laser process which can remove material molecule-by-molecule in a controlled fashion, and which can be readily halted once the final finish is achieved. We will research this technique for application to unique Australian heritage materials that are important to the specific conservation needs of the Australian War Memorial, the RAAF, Navy and Army Museums, Artlab Australia, and the Art Gallery of NSW.Read moreRead less
Laser cleaning processes for Roads and Maritime Services bridges. This project aims to develop innovative laser cleaning processes to conserve the structural integrity and iconic status of the Sydney Harbour Bridge. New laser technologies offer the opportunity to remove lead-based paint and clean the bridge’s metal structures and granite pylons offering advantages unavailable with current techniques. The expected outcomes will be new best-practice laser conservation techniques usable for both ha ....Laser cleaning processes for Roads and Maritime Services bridges. This project aims to develop innovative laser cleaning processes to conserve the structural integrity and iconic status of the Sydney Harbour Bridge. New laser technologies offer the opportunity to remove lead-based paint and clean the bridge’s metal structures and granite pylons offering advantages unavailable with current techniques. The expected outcomes will be new best-practice laser conservation techniques usable for both hand-held and automated systems to preserve one of the most iconic bridges in the world. This will reduce maintenance frequency and cost, restore the beauty of the bridge, retain its engineering significance and provide a baseline process for cleaning of other historical large scale metal and stone heritage objects.Read moreRead less
Development of Novel Concrete Noise Walls Incorporating Recycled Materials. This project will develop high-performance, lightweight, concrete noise walls and acoustic barriers that use recycled tyre and glass products to improve sound absorption, and address environmental problems associated with the mining of river sands, and stockpiling of waste tyre and glass products. Innovation in noise wall technology consists in developing low-carbon concrete mixes (using less cement) with a maximum amoun ....Development of Novel Concrete Noise Walls Incorporating Recycled Materials. This project will develop high-performance, lightweight, concrete noise walls and acoustic barriers that use recycled tyre and glass products to improve sound absorption, and address environmental problems associated with the mining of river sands, and stockpiling of waste tyre and glass products. Innovation in noise wall technology consists in developing low-carbon concrete mixes (using less cement) with a maximum amount of recycled product, together with reducing wall thickness, while maintaining the necessary engineering properties such as acoustics, strength, and durability. In addition to higher acoustic insulation, the novel low-carbon, lightweight, panels will improve material handling and affordability of noise barriers.Read moreRead less
