  1 Cedar Corner: High Volume Fly Ash Concrete Implementation Summary Report
    Document Type: Case Study Report
    Publication Date: July 3, 2003
Author(s): Kyle Dolan, E.I.T., Levelton Consultants Ltd
    Cedar Corner development in Tofino, B.C. is a LEED-registered project in which construction was based on sustainable principles. The project consists of a three level structure to be utilized for mixed commercial space, including a pub and restaurant. The entire structure was built from recycled building materials and high volume fly ash (HVFA) con...[more]

  2 Characteristics of Metakaolin and its Use in Concrete
    Document Type: Presentation
    Publication Date: 2001
Presenter(s): Benoit Fournier
    This presentation provides an overview of metakaolin as a supplementary cementing material, and concludes that metakaolin is a highly pozzolanic and reactive material which improves most mechanical and durability properties of concrete, and that the properties of concrete incorporating metakaolin are comparable and sometimes better than silica fume...[more]

  3 Effect of Low Curing Temperatures on Selected Properties of Concrete Incorporating Large Volumes of Fly Ash
    Document Type: Technical Report
    Publication Date: November 2001
Author(s): R. Chevrier, Alain Bilodeau
    The main objective of this project was to observe the effect of low-curing temperatures on the setting time, strength development and resistance to chloride-ion penetration of concrete incorporating large volumes of fly ash. The internal temperature of various size specimens was also monitored.

The study found that the properties of both the...[more]

  4 Evaluation of the Potential Use of the Superplasticizer ALPHALITH FT30LV with Canadian Cements
    Document Type: Technical Report
    Publication Date: September 2003
Author(s): Benoit Fournier, Pierre-Claver Nkinamubanzi, CANMET Energy Technology Centre, Natural Resources Canada
    ECTechnology, Vancouver, via EcoSmart, provided ICON CANMET with a new superplasticizer produced by Rhein Chemotechnik GmbH, Breitscheid Germany, the ALPHALITH FT30LV, which meets the European standards and certifications for analyzing and testing of its suitability for the Canadian market. The superplasticizer belongs to the family of naphthalene...[more]

  5 Fly Ash Concrete Trials, Government of Canada Building, Yellowknife NT
    Document Type: Case Study Report
    Publication Date: March 31, 2004
Author(s): EBA Engineering Consultants Ltd.
    In the Spring of 2004, Public Works and Government Services Canada (PWGSC) will be constructing a new low-rise office building in Yellowknife, NT. EBA Engineering Consultants (EBA) was retained to review the concrete specifications for the project and to complete the laboratory trials to assist in confirming the feasibility of using fly ash to repl...[more]

  6 Low Heat and Eco-Friendly Fly Ash Concretes
    Document Type: Technical Report
    Publication Date: June 9, 2008
Author(s): David Cooney, Unibeton
    This report tested a number of fresh and hardened properties of fly ash concretes including: bleeding, compressive strength, finishability, heat of hydration, penetration of chloride ions, plastic properties, pumpability, setting time, shrinkage, slump and slump retention, stripping strength, and water reduction. Results demonstrate that fly ash...[more]

  7 Mechanical Properties and Durability of Concrete made with HVFA Blended Cement Produced in a Cement Plant
    Document Type: Technical Report
    Publication Date: October 2001
Author(s): Nabil Bouzoubaa, Benoit Fournier, V.M. Malhotra, D.M. Golden
    This paper presents the results of a study on the mechanical properties and durability of concrete made with high volume fly ash (HVFA) blended cement produced in a cement plant. The test results obtained were compared with those of a control concrete made with a commercially available ASTM Type I cement; the control concrete had a 28-day compressi...[more]

  8 Production and Performance of Laboratory Produced High-Volume Fly Ash Blended Cements in Concrete
    Document Type: Technical Report
    Publication Date: April 19, 1999
Author(s): Nabil Bouzoubaa, M.H. Zhang, V.M. Malhotra, CANMET Energy Technology Centre, Natural Resources Canada
    This paper reports on CANMET's development of high volume fly ash (HVFA) blended cements, and their performance in concrete. The blended cements are made by intergrinding approximately 55% of fly ash and 45% of ASTM Type I or Type III cement clinker together with small amounts of gypsum and a dry superplasticizer. The concrete made with the HVFA b...[more]

  9 Properties of Fly Ash Concrete Mixtures Made with Materials from the United Arab Emirates
    Document Type: Technical Report
    Publication Date: June 9, 2008
Author(s): Alain Bilodeau, Nabil Bouzoubaa, R. Chevrier, Pierre-Claver Nkinamubanzi, CANMET Energy Technology Centre, Natural Resources Canada
    A total of four concrete mixtures were made. These included one control concrete without fly ash, and three mixtures incorporating different percentages of fly ash. In addition to the standard compressive strength determination under normal moist-curing conditions, the effect of curing and ambient temperature on the strength and some durability c...[more]

  10 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]
