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.

Faiz Khan our Structural Durability Engineering Specialist presented to a gathering of durability enthusiasts in Melbourne at Australasian Concrete Repair Association (ACRA) and Australasian Corrosion Association (ACA)’s joint event on “Using Chloride Levels to Predict Service Life of Structures”. Faiz spoke about how critical chloride content should be used in the assessment of new and existing structures, based on latest considerations for inclusion in fib’s Model Code 2020. It included comments and recommended values of Cc for normal reinforcing, galvanised rebar, stainless steel and steel fibres. The talk also outlined considerations which are being made in the development of this standard, which is likely to be consistent with ISO and EN standards; such as why there is such a broad distribution for chloride content levels which result in corrosion and how other factors are being considered in these standards which may impact on critical chloride levels. BCRC’s Frank Papworth is chair of the fib committee dealing with this subject and provided helpful insights onto these developments.

Following some tragic building fires related to aluminium composites façade panels the Australian building industry has engaged on a rigorous process of façade flammability assessment. BCRC are part of this industry led initiative and are undertaking investigations of aluminium clad composite façade materials. A series of laboratory testing of samples enables an analysis of flammability risk. This test series does not replace methods associated with Australia Standards AS 1530.1—1994 or similar, however it does give a scientifically based assessment of the risk of flammability. For information contact Marton Marosszeky on 0412446916 or contact your local BCRC state manager for a quote.
March 2018
In March Shane Connelly, BCRC’s recently appointed Victorian manager and Marton Marosszeky, managed BCRC’s exhibit at the ACE Body Corporate Management Conference in Hobart. This was a great opportunity to meet members of Australia’s third largest strata management network, and to hear current issues in the residential strata industry being discussed. One topic of great interest was the flammability problem with the use of aluminium composite claddings, this is an area in which BCRC testing is providing asset owners and their consultants an understanding of the fire risk their facades pose. Contact BCRC’s local manager in your state today for more details on how BCRC can help expertly manage durability and materials-related issues such as this.

BCRC recently undertook an assessment of a structure where there was concern about cracked concrete piles in seawater and brine. A comprehensive analysis was undertaken incorporating the research finding of Carmen Andrade showing that underwater corrosion was not prevented by oxygen starvation at the cathode. The high performance of immersed concrete was more to do with a very high activation level where the reinforcement is surrounded by water at high pH. The low activation levels found on many structures is more to do with unsaturated voids at the bar. For more information contact Frank Papworth.
Oct 2017
The BCRC team will present various papers at the ICDC and Concrete 2017 conferences running in parrelel in Adelaide. Topics covered will incude maturity, insitu strength assessment, durability planning and assessment of a lithium bi-product for use in concrete.

BCRC are pleased to announce an agreement with Ingenieurburo in Munich, Germany. Ingenieurburo was started by Professor Peter Schiessel, world famous for his concrete durability research from 1970’s to present day. Ingenieurburo partners are internationally recognised for a range of concrete related services, particualrly modelling of concrete behaviour, and it is in this developing and important field that BCRC and Ingenieurburo will work on together in Australia and New Zealand.
Ingenieurburo’s manager for this agreement is Christoph Gehlen and BCRC’s is Frank Papworth. Christoph’s lead on two reports for fib demonstrate how Ingenieurburo are setting the standard for concrete testing and chloride ingress and carbonation rate modelling. fib Bulletin 59 descibes testing of existing structures using correct procedures for the number of samples required to achieve a given level of confidence in corrosion assessment. fib Bulletin 76 provides an assessment of the reliability provided by deemed to comply requirements in current national codes, including AS 3600. There are few companies that undertake full probabilistic modelling and even fewer that have sufficient background to know how to manage the input parameters. With input from Ingenieurburo BCRC can provide the latest methods for modelling concrete durability.
2nd June 2016
BCRC moved to a office at 949 Wellington Street, West Perth. The move provides greater space for this growing office and the location is convenient to BCRC’s customer base in the Perth city area.
22nd March 2016
Frank Papworth gave a presentation aimed at young corrosion engineers on ‘Repair of Reinforcement Corrosion’ to ACA in Perth. The presentation outlined the procees to follow for inspection in order to define repair requirements. It also outlined some of the pitfalls that can be made and gave examples of major errors.
17th Nov 2015
Jonathon Dyson delivered a paper detailing a new method for selecting anode systems for cathodic protection for concrete repair at the ACA annual conference on corrosion in Adelaide. Typically anodes are selected based only on the contractor or designers preference with little clear reference to the owners needs. In this BCRC approach weighted ratings are given to various client requirements and costs. The selection procedure is then worked through with the owner who will have to live with the selected system. The paper also gave details of why different sacrificial anodes are used to control ‘incipient anodes’ (halo effect) to those for cathodic protection.

9th Oct 2015
Frank Papworth gave three presentations at the International Conference on Concrete Repair, Rehabilitation and Retrofitting in Leipzig. One presentation compared the current requirements in Australia for assessment of strength in structures with the British and European practices. It showed that the Australian process is out of date and that the UK practice is probably the more statistically correct approach to take.
Dec 2014
Frank Papworth was awarded the Dr V.M. Malhotra Award for outstanding and sustained contributions to the broad area of durability of concrete. This award came as a complete surprise to Frank but was accepted as a great honour not least because of the high renown of Mohan Malhotra but also the excellence of the conference series (International Congress on Durability of Concrete) where the award is given. Frank delivered four papers at the conference largely related to the various CIA Recommended Practice notes being produced as part of a Durability Series. The 2017 ICDC will be held in Adelaide in October.
