In this case study of the Nicola Valley Institute of Technology -NVIT- the use of high volume fly ash concrete presented a significant challenge because of the longer set-up times required during cold weather placing temperatures and resulted in increased costs. Despite the challenges presented by cold weather concreting the original goal of almost 40% fly ash replacement of cement averaged for the entire placement of concrete was reached. The report makes recommendations for future use and acceptance of EcoSmart concrete.

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 trades’ 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.
