Speakers:
Professor Stephen Foster, Dean Emeritus Engineering, UNSW Sydney
Doctor James Aldred, Technical Director, Concrete Future and AECOM (casual)
PRESENTATION DETAILS:
Design procedures and structural considerations when using geopolymer or alkali activated binder concrete in accordance with AS TS 199. By Professor Stephen Foster.
Synopsis: The recently released SA TS 199:2023 “Design of geopolymer and alkali activated binder concrete (GPC and AABC) structures” provides requirements and guidance for the design and construction of alternative binder concrete building structures and members that contain reinforcing steel or tendons, or both. This presentation looks at how GPC and AABC structures can be designed for ultimate strength and serviceability limit states as set out in AS/NZS 1170.0 and AS 3600. The models developed AS TS 199 for predicting deformation due to shrinkage and creep of GPC and AABC will also be discussed.
Material properties of geopolymer or alkali activated binder concrete. By Dr James Aldred.
Synopsis: There are many different geopolymer and alkali activated binder concrete (GPC and AABC) systems available with a wide range of material properties. AS TS 199:2023 provides guidance on both systems that achieve their hardened properties at ambient temperature and systems that are heat cured. GPC and AABC have been the subject of much research and offer alternatives to ordinary Portland cement (OPC) based concrete in a variety of applications. Potential benefits of concrete may include improved chemical resistance and reduced CO2 impact. This presentation discusses the mechanical and durability properties of GPC and AABC and the recommended performance requirements for their use in building structures and members designed to AS/NZS 1170.0 and AS 3600. Some practical considerations when using these alternative binders are presented as well as examples of structures and members constructed with GPC and AABC.
The webinar will run from 2.00pm to approximately 4.00 pm (AEST) and delegates will be emailed login details and a password for this webinar prior to the event.
