One of the most significant breakthrough developments in concrete technology at the end of the 20th century was that of ultra-high performance ‘ductile’ concrete (UHPdC) with compressive strength up to 200 MPa and remarkable improvements in…

Reinforced concrete made its way into road bridges at the start of the twentieth century after being invented by Joseph Monier in 1875. By 1950 reinforced concrete was dominant for small and medium spans and vying with steel for longer spans. Their…

The Sulfate-resisting concrete is traditionally specified by cement type and concrete mix proportions in terms of maximum water-cement ratio and/or minimum cement content.

A wide range of test methods has been used to measure the resistance of concrete to chloride penetration. Each method is purported to measure the property of concrete central to the chloride transport mechanism into concrete. They include water…

The standard Super-T bridge girders used in Australia were developed to provide optimum performance at a time when the maximum concrete grade covered by the bridge design code was 50 MPa. This paper examines the opportunities for improved…

The Banora Point Upgrade Alliance (BPA) project involves an upgrade of the 2.5 kilometer length of Pacific Highway through Banora Point, in northern NSW. The proposed upgrade will provide a link between the existing Chinderah bypass and Tweed…

Self-compacting concrete (also known as Super-workable concrete in Australia and Self-consolidating concrete in North America) is defined in EN 206 Part 9: Additional Rules for Selfcompacting Concrete (SCC) as concrete that is able to flow and…

Durability design of piles is usually carried out based on AS 2159 and AS 3600. It is widely known that the durability of concrete in acid sulphate environments is significantly influenced by the type of binder

The Roads and Traffic Authority of NSW (RTA) has had various concerns regarding the quality of the “cover concrete” produced by contractors and suppliers using certain types of bar chairs in the manufacture of concrete products for RTA bridges.…

Geopolymer concrete consists of the normal components of fine and coarse aggregate, any required admixtures and aluminosilicate based industry byproducts such as fly ash and ground granulated blast furnace slag which can be activated with a…
