  • 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.

Don’t miss out and Register now!!!

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.

Graph: Demonstrating 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.

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.

ACA Seminar ‘Maximising Durability in the Water Industry’

Maximising Durability in the Water Industry image 3

Mr Frank Papworth presented some thoughts on durability design based on BCRC’s experience on some major projects.

The first major desalination project in Australia (Perth Desalination Plant – right) showed the difficulty of correct exposure identification in process buildings. This has been a major failing on many building projects.

Other problems resolved on desalination projects included appropriate corrosion allowance for steel fibre segments for brine pitfalls, provisions for cathodic protection of diaphragm walls in severe exposures, exposure assessment of seawater tanks not kept full and crack control of tanks to prevent long term leakage. 

The theme of crack control design was continued for large slab pours of Kalgoorlie’s 400GL reservoir (right), and particularly for settlements of inclined walls. The development of 100% joint testing by vacuum box was also described. 

Experience with acid attack from hydrogen sulphide exposure centred on how limited attack of the concrete and reinforcement was ahead of the attacking front. The presentation concluded by showing the potential durability of concrete for water industry by discussing the inspections of three 100+ year old water tanks.
