In the search for durability, researchers in Canada and in other countries sought for higher performance materials. Technology from other countries, notably France, Norway, Japan and Germany, was incorporated into developments in Canada in the 1980s. High Performance Concrete (HPC) was included in this research. With the establishment of Concrete Canada (CC) in 1990, a co-ordinated and concentrated programme of research commenced. In 1994, this programme expanded to include demonstration projects to implement HPC technology on construction sites. Technology Transfer was a primary goal of CC. Many seminars, workshops and technology transfer days were held across Canada, by CC alone, in co-operation with American Concrete Institute (ACI) Chapters, the Cement Association of Canada (CAC) and its member companies, and for specific entities such as Provincial Highway Departments and Cities.
Between 1990 and 2000, CC researchers published over 400 Papers in scientific journals. It seemed appropriate, as the old millennium ended, to assess the practice in the use of HPC in Canada over the past 10 years. The extent of its use, the varying specifications, results, economics and problems encountered have been reviewed. Looking ahead, areas for ongoing research and development have been identified. The study demonstrates that, for those who have correctly implemented this technology, HPC is the high quality concrete of choice for high strength, durability and optimum lifecycle costs.
