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.

Fast and Epp s investigative report reviews the potential use of high volume fly ash concrete in high rise construction in a way that introduces no cost premiums to the existing construction process. The report concludes that an hvfa mix that is transparent in terms of set times and cure rates is not practical at this time and that the best opportunity for HVFA usage lies in the podium and parkade areas of typical highrise buildings.

The report details the use of EcoSmartâ„¢ concrete in the construction of the Bayview a high-rise residential/commercial building. The contractors found that EcoSmartâ„¢ concrete was easy to work with in terms of pumping placing and vibrating and produced a beautiful architectural concrete. Although the contractor did not commit to using higher levels of fly ash before construction fly ash percentages for concrete components were increased by approximately 13% over the contractor s standard low fly ash mixes. The report suggests that current highrise construction practices must be revised before EcoSmartâ„¢ concrete can be used cost-neutrally.

The report analyzes the economical technical and business impacts of using EcoSmart concrete in Cranberry Commons a multi-unit residential construction project. The Cranberry Commons Cohousing Development Corporation chose to incorporate EcoSmart concrete because of their dedication to implementing environmentally sustainable building technologies throughout their building. Although the concrete took longer to set it did not effect the scheduling of the project. The use of EcoSmart concrete meant that the contractors were able to reduce cement content by 32%.

This report describes the use of fly ash concrete in an office building: the BC Gas Operations Centre in Surrey BC. A broad range of environmental goals were identified early in the design development phase including the goal of using high volume fly ash -40%- thus embedding the project s green goals into the project specifications in time for tendering of the the tradesâ€™ sections. The high volume fly ash mixes were found to be easier to place than conventional mixes and cost less. The recommendations that arose from this project are to set clear goals at the outset involve the whole team in decision making take longer curing times into account in the project scheduling and clearly specify the fly ash objectives in the contract documents. Includes concrete pour data and several photos.
