The report details the current situation of supplementary cementing materials -SCMs- in Canada specifically in terms of production cost availability usage potential areas for increasing usage local barriers and relevant guidelines and specifications. The purpose of the study is to determine a strategy to increase the use of SCMs in Canada.
The data show that approximately 524 000 347 000 and 37 000 tonnes of fly ash Ground Granulated Blast Furnace Slag -GGBFS- and silica fume were used in cement and concrete applications in 2001. These amounts represent 11 90 and 185% of the quantity produced respectively. Thus fly ash appears to be the only material that is underused and that represents a potential for increased use of SCMs in Canada.
The investigation also shows that there are policy technical and economic barriers to the increased use of SCMs in Canada. The report suggests several solutions to overcome these barriers.
Includes an extensive list of tables.
