8 Documents associated with: Supplementary Cementing Material >Silica fume
  1 Current Situation of Supplementary Cementitious Materials (SCMs) in Canada
    Document Type: Technical Report
    Publication Date: April 2003
Author(s): Nabil Bouzoubaa, Benoit Fournier, CANMET Energy Technology Centre, Natural Resources Canada
    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....[more]

  2 Development of Ternary Blends for High-Performance Concrete
    Document Type: Technical Report
    Publication Date: July 2002
Author(s): Nabil Bouzoubaa, Alain Bilodeau, Benoit Fournier, V. Sivasundaram, D.M. Golden, CANMET Energy Technology Centre, Natural Resources Canada
    The purpose of this study was to develop ternary blends with optimum amounts of fly ash and silica fume to be used in high-performance concrete. Two series of air-entrained concrete mixtures were investigated in the study: series 1 included concretes with a total cementitious materials content (CM) of 350 kg/m 3 , and a water-to-cementitious materi...[more]

  3 EcoSmart Concrete in the Quebec Context: Mountain Equipment Co-op, Montreal
    Document Type: Case Study Report
    Publication Date: August 2003
Author(s): Studio MMA, Atelier d'architecture
    The Mountain Equipment Co-op Montreal store is the Co-op's 8th retail store and the third (after the Ottawa and Winnipeg stores) to comply with Natural Resources Canada's C2000 Green Building Standard. It is the first C2000 compliant retail building in Quebec.

The decision to use EcoSmart concrete was based on the project's environmental obj...[more]

  4 Interim report on Fly Ash concretes for EcoSmart
    Document Type: Presentation
    Publication Date: October 24, 2007
Author(s): David Cooney, Unibeton
    At the October 2007 EcoSmart Concrete Seminar in Abu Dhabi and Dubai, UAE, Cooney presented the results of the first phase of tests on concrete samples containing various amounts of FA. Samples were obtained from companies in the UAE. Cooney described the mix designs and tested their mechanical properties. This included slump, setting time, heat...[more]

  5 Performance of Mortars Incorporating Finely-Ground Fly Ash
    Document Type: Technical Report
    Publication Date: May 2000
Author(s): Nabil Bouzoubaa, V.M. Malhotra, CANMET Energy Technology Centre, Natural Resources Canada
    This paper presents results on the compressive strength of mortars in which 10 and 20% of ASTM Type I cement has been replaced by ground fly ash from two different sources. The results are compared with those of the mortars made with ASTM Type I cement, and with the mortar in which 10% of portland cement has been replaced by silica fume. The result...[more]

  6 Sandheads Light Structure: A Case Study of High Volume Flyash Concrete
    Document Type: Case Study Report
    Publication Date: April 30, 2002
Author(s): Brian Konrad
    EcoSmart concrete was used for the piles, pile caps and precast panels of the new light station at Sandheads. High volume fly ash (HVFA) concrete provides greater strength and less permeability, which will result in a higher durability in the harsh marine environment. In the case of this project, the slower setting time of HVFA concrete was benefic...[more]

  7 The Role of Superplasticizers in the Development of Environmentally-Friendly Concrete
    Document Type: Technical Report
    Publication Date: April 19, 2000
Author(s): Monique Page, Nelu Spiratos
    Since their introduction in the early 60’s, superplasticizers have become an essential component of concrete. By reducing the amount of water in concrete, superplasticizers have contributed to a significant reduction in its porosity and to a concomitant increase in its compressive strength and durability. These chemical admixtures have also been at...[more]

  8 The Use of High Volume Fly Ash in Concrete
    Document Type: Technical Report
    Publication Date: 2003
Author(s): M.D.A. Thomas, D.S. Hopkins, Gurinder Girn, Robert Munro, Ernese Muhl
    This paper presents data from durability studies of concretes containing up to 60% fly ash; studies include carbonation, chloride resistance, permeability and strength. Data are also presented from a recent construction project in Toronto where high-volume fly ash concrete was used as part of a “Green Building Strategy”. Finally, the paper presents...[more]
