In 2000-2001 Australia spent 17.5 billon dollars on heavy engineering infrastructure development (3% of its gross domestic product). As this infrastructure ages costs of repairs and maintenance magnifies. Conventional structural concrete can significantly deteriorate with time requiring regular and often costly maintenance. This research goes to the development of a class of "super" concretes with very high strengths and with excellent durability properties. With improved understanding of fracture and fracture processes with these materials, new models can be developed to represent the behaviour of structural elements fabricated with this "super" class of concretes and speed their implementation into Australian construction practice.

2000-2001年，澳大利亚在重型工程基础设施发展上花费了175亿美元（占其国内生产总值的3%）。随着这些基础设施的老化，维修和维护的成本也在增加。传统的结构混凝土会随着时间的推移而严重恶化，需要定期且通常昂贵的维护。本研究旨在开发一类具有非常高强度和优异耐久性的“超级”混凝土。随着对这些材料的断裂和断裂过程的进一步了解，可以开发新的模型来代表用这种“超级”混凝土制造的结构元件的行为，并加快其在澳大利亚建筑实践中的实施。
