|Accelerated Evaluation of the Effectiveness of Supplementary Cementitious Materials to Suppress Damaging AAR Expansion in Concrete Structures
This report provides the results of testing of three potentially reactive aggregates by the accelerated mortar bar test (AMBT) and the concrete prism test (CPT). The testing program investigated whether the much faster AMBT method could be employed instead of the slow CPT method for the evaluation of the efficiency of supplementary cementitious materials to suppress alkali-aggregate reaction in concrete.
|Specification and Use of Geopolymer Concrete in the Manufacture of Structural and Non-structural Components: Review of Literature
This report reviews published information on the formulation, manufacture and properties of geopolymer binders and concretes, to inform the manufacture of geopolymer concrete components for structural and non-structural bridge components and other road‑related infrastructure.
|Realising 100-year Bridge Design Life in an Aggressive Environment: Review of the Literature
This report details a literature review on durability issues that affect the service life of reinforced concrete structures.
|Realising 100-year Design Life of Bridge Structures in an Aggressive Environment: Experimental Work
This report summarises the results of experiments undertaken to understand the practices required to enable a 100-year design life of bridges in an aggressive environment.
|Specification of Geopolymer Concrete: General Guide
This general guide contains: an introduction to geopolymer concrete, its constituents and how it is manufactured; an examination of how geopolymer binder differs from Portland cement; and the status of geopolymer concrete as a construction material.
|Improved Bridge Deterioration Models, Predictive Tools and Costs
In this report, state-of-the-art deterioration modelling techniques are reviewed highlighting the advantages and limitations of each approach. The findings indicate that currently deterioration modelling is potentially difficult to implement in the Australian and New Zealand context, given the lack of integration of the data sets with existing bridge asset management tools.
