BCRC proudly announces its participation as a Keynote Speaker Partner for Oscar R. Antommattei at the CIA event – Concrete 2021 (5-8 September).
Experience an engaging and exciting virtual program including keynote speakers, invited speakers and over 150 technical presentations. The four-day program will bring together global leaders in the concrete industry, covering all aspects of concrete materials, design, construction, repair, and maintenance, to discuss and share information on how innovation and smarter thinking will allow us to deal with disruption.
Team BCRC is presenting Multiple Papers at CONCRETE 2021 (5-8th September):
Our director Frank Papworth will give a presentation on the importance of using the right model for durability design. He uses the simple graphs below to show that the equations used to predict depths of critical chloride level, and carbonation depth, over time must recognize that the variables in the formula are distributions. Because this is not fully detailed in simple models like Life 365 and CSTR 61 engineers judgement on the suitability of different materials is often flawed. The paper also explores they way forward with full probability analysis (FPA) in the design of structures.
In a separate paper our Herman Jong shows how the FPA has been used to check AS5100.5 Deemed to Satisfy requirements. Frank will also team with Rodney Paul in a session on the work of the fib and CIA Durability Committees.
Quite separate to that our Gulraiz Ijaz presents on innovate sacrificial anode for cathodic protection that meet code criteria while our Robert Munn (Bob) provides an update on a lithium byproduct for use in concrete.
BCRC Consultants Rebecca Newby and Summer Wang undertook a durability assessment of six bridges located throughout Tasmania as part of repair work scheduled for the structures. BCRC completed the following activities:
Visual inspection and drummy survey
Rebound hammer testing
Analysis and reporting with remediation recommendations

BCRC Engineers Gulraiz and Inam inspecting a Sydney Harbour Wharf for Concrete Durability prior to redevelopment of the Wharf. They are sampling the concrete which will be laboratory tested and the results analysed to assess each element’s residual life based on the reliability required.
Target reliability is emerging as one of the most important factors in durability design. It was first introduced into Australian methodology in CIA’s Z7/01 by BCRC’s Frank Papworth.
They are also using an advanced Ground Penetrating Radar (GPR) that uses stepped frequency antenna and downloads data automatically to the internet. It is revolutionising how reinforcement is visualised in concrete and provides rapid scanning of concrete cover distribution, a vital input into full probabilistic durability design.
We have a wide range of cutting-edge concrete Non-Destructive Test devices, making BCRC Australia’s industry leader in the concrete inspection field. Methods such as, Ultrasonic Pulse Echo (UPE), Impact Echo (IE), Impulse Response (IR), Cross Hole Sonic Logging (CHSL) and Spectral Analysis of Surface Waves (SASW) are some of the advanced methods we utilise for evaluating concrete structures.
In each case, stress waves or electromagnetic waves are introduced into the concrete and reflected waves or structure responses are measured. These methods have seen rapid development and acceptance in many countries in Europe, North America and Singapore. All are now used in Australia through BCRC.
