An investigation of high-volume fly ash concrete for pavements

This thesis investigated the use of fly ash in concrete by establishing reliable and accurate test data on the properties of concrete incorporating different fly ash content. In addition, the study focussed on typical uses by local government authorities in pathways, such as footpaths and bicycle ways, and also looked at environmental impacts, incorporating durability and construction constraints in the life cycle costing issues. The aims of the project were: 1. to obtain experimental data on mechanical properties and durability characteristics of fly ash concrete containing 23-50 per cent fly ash with a 28-day compressive strength of 25MPa; 2. to assess the effect of curing on the properties of concrete incorporating different percentages of fly ash; and 3. to draw conclusions as to the cost effectiveness of concrete incorporating large amounts of fly ash by comparing life cycle assessments that include durability, construction and environmental factors.
