This presentation from GLOBE 2002 provides an overview of the issues and concerns associated with the use of fly ash and other supplementary cementing materials in concrete including ground slag cement -GS-Cem- natural pozzolans and metakaolin. Also introduces the EcoSmart project and the EcoSmart case studies. This presentation was part of Session 6: Innovative Technology Applications: Partnerships and Networks.

This study investigates the implications of using high volume fly ash -hvfa- concrete in skytrain station components particularly in Brentwood and Gilmour stations in Burnaby. The study provides a strategy to optimize the percentage of fly ash in the concrete without affecting the construction schedule recommends using a minimum of 50% fly ash in the footings walls columns slabs and stairways recommends using a minimum of 30% fly ash concrete in precast elements and estimates that costs will be about the same or possibly less than using conventional concrete.

This report assesses the use and performance of EcoSmartâ„¢ -high volume fly ash- concrete in the Liu Centre for the Study of Global Issues – a new research and conference facility at the University of British Columbia. It is intended to complement existing published material with the addition of project specific data and experiences supplied by the design team general contractor and material suppliers. The experience of using EcoSmartâ„¢ concrete is evaluated according to its contribution to achieving set project goals and its measurable environmental benefits.
Case Study Report Author: Richard Klopp, Architectura,
Following a brief introduction to the EcoSmartâ„¢ Concrete Project and its mandate of working with the cement and concrete industry to decrease greenhouse gas -GHG- emissions from that industry the report highlights the case studies that were undertaken during the project in 1999/2000. The report summarizes the most significant findings of various case studies which include practical solutions to the technical challenges that were identified while working with EcoSmartâ„¢ concrete on construction sites. In addition to the case study findings the fly ash infrastructure -types and uses of fly ash- is described once again offering practical advice on working with high volume fly ash concrete. A review of the technical advances in concrete production is provided offering the highlights of the innovations that have taken place in intergrind and precast technologies. The report concludes with an illustration of the CO2 emission potential of using EcoSmartâ„¢ concrete and several recommendations for future work.
