Overview

Design doesn't need to be compromised in order to comply with strict rules and regulations for concrete pavements, footpaths and urban streetscapes. By utilising colour, textures and finishes, it is possible to create a surface that is both beautiful and meets the required standards. The application of colour applies to both new and existing concrete, with multiple options to refresh and revive old concrete. It is popular across Australia due to its versatile, durable and low maintenance characteristics, especially when compared with alternatives such as natural stone or pavers.

New perspectives for the understanding of reinforcement corrosion in marine concrete structures.  
Existing theory and models do not well-predict the onset of chloride-induced reinforcement corrosion compared with observations and practical experience for actual concrete structures. Very high levels of chlorides may initiate some reinforcement corrosion in more permeable concretes, but then declines depending on the rate of oxygen availability. For high quality, low permeability concretes the early corrosion usually stops or becomes very slow. For such concretes serious corrosion does not commence until there is extensive loss of concrete calcium hydroxide through leaching to the environment. This is accelerated by the presence of chlorides. Evidence from actual concrete structures shows that this is a very slow process, with little loss even after 75-85 years. The reasons for this are described. The observations and inferences are considered to require a re-appraisal of conventional ideas and concepts associated with ‘chloride-induced’ reinforcement corrosion.  


Performance of Concrete Mixes by Chloride Durability Test Methods, and Assessment of Factors Contributing to Concrete's Resistance to Chloride Ingress   
This webinar will look at actual chloride durability test results of various concrete mixes when assessed by a number of different recognised chloride durability test methods. There will be some discussion around limitations of the test methods in highly durable concrete, possible modifications to those methods and a review of factors affecting concrete's ability to withstand ingress of chlorides. Boral has embarked on a multi-year program of trials with both conventional and improved cementitious materials and this webinar will include some of the findings from these trials.

Jason is currently a project manager for Boral Concrete. Previously he has worked in Boral's NSW Technical department and in that time developed an interest in concrete sustainability and durability. From this interest he was instrumental in the development and commercialisation of Boral's low carbon, low shrink, high durability ENVISIA concrete and has presented papers at the last two CIA bi-annual conferences.
