Prediction of Time-dependent Deformations in Post-tensioned Concrete Suspended Slabs in Tall Buildings. The proposed project aims to develop an analytical model that can predict the time-dependent deformations in post-tensioned concrete slabs considering concrete shrinkage and creep, cracking, and bond-slip behaviour. Over the past several years, numerous cases have been reported in Australia and elsewhere, of flexural elements for which the calculated deflection is far less than the actual defl ....Prediction of Time-dependent Deformations in Post-tensioned Concrete Suspended Slabs in Tall Buildings. The proposed project aims to develop an analytical model that can predict the time-dependent deformations in post-tensioned concrete slabs considering concrete shrinkage and creep, cracking, and bond-slip behaviour. Over the past several years, numerous cases have been reported in Australia and elsewhere, of flexural elements for which the calculated deflection is far less than the actual deflection leading to serviceability problems. The significance of this investigation hence lies in its potential to provide a solution to more accurately predict service-life deflections in post-tensioned concrete suspended slabs and validate the model with real-life deflections monitored over time on a current building project.Read moreRead less

The project aims to develop high performance concrete structures using 3D printing techniques. 3D printing of concrete is receiving increasing attention because of its potential use for direct construction of buildings and other complex infrastructures of considerable dimensions and of virtually any shape. This project aims to develop high-performance concrete structures reinforced by multiscale (nano- and micro-fibre) fillers using 3D printing. The project plans to introduce a micro-fibre 3D mesh into the concrete with a ‘knitting’ technique. The outcome of the project may lead to a 60 per cent reduction in current manufacturing cost and reduction of the lead-time for concrete infrastructures.Read moreRead less

By incorporating different nano-materials in well cements, this project aims to develop multi-functional cementitious materials with self-sensing properties and greater strength and durability under extreme conditions including high/low temperatures, high pressure and corrosive environments. The integrity and longevity of well cement are paramount for the safe, efficient, environmentally sustainable production of oil and natural gas resources. Cementing problems are the main factor contributing to incidents during drilling and completion of wells, necessitating costly remediation. It is expected that the novel cement developed in the project will produce safer wells with fewer (gas) environmental emission risks.Read moreRead less
