RILEM Youth Council Pacific Webinar: Viability of LC3 in Australia, recent innovations in geopolymers and ultra high performance concrete

The first RYC Pacific webinar will take place on Tuesday April 25th, 2023 at 5PM Sydney Time and will be one hour and a half long (4*15 minutes presentations + 20-minute Q&A). The registration for this webinar is free.

Theme: Viability of LC3 in Australia, recent innovations in geopolymers and ultra high performance concrete

Speaker 1: Emily Canda, University of Technology Sydney
Title: Exploration of Australian Clays as a Supplementary Cementitious Material
Clays from around Australia that are considered over-burden are analysed and partially characterised to determine their feasibility in the application of LC3. Based on these results various experiments were conducted in the expectation of creating a viable sustainable concrete product for the Australian market.

Speaker 2: Shravan Muthukrishnan, Swinburne University
Title: Set-on-demand geopolymer for 3D concrete printing (3DCP)
The use of geopolymer as cement substitute improves the sustainability of 3DCP. Traditional geopolymers however have lower pumpability and buildability than cementitious mixes, restricting geopolymers’ application in large-scale construction. To solve this, we have developed a set-on-demand geopolymer concrete which has an open time of 24+ hours and buildability of ~80 m/h.

Speaker 3: Sherin Khadeeja Rahman, Deakin University
Title: A Novel Self-Compacting Geopolymer Concrete-Basalt FRP Composite for Marine Applications
Combining self-compacting geopolymer concrete with Basalt Fibre Reinforced Polymer (BFRP) bars produces a novel composite construction material with non-corrosive properties. This composite product is found to perform better in seawater civil structures without any strength deterioration or corrosion as opposed to the conventional marine structures.

Speaker 4: Shameer Saleh, University of New South Wales
Title: Industrial By-product Based Low Carbon Seawater and Sea-sand Ultra-High-Performance Concrete
This study summarizes the outcome of an experimental study that fully replaces natural aggregates of ultra-high-performance concrete with sea-sand, up to 62.5% cement with slag and silica fume as SCMs, and reticulated mix water with seawater. Results demonstrate that SCMs in ultra-high-performance seawater and sea-sand concrete significantly improve transport properties and durability.
