  • Chloride ions are bound into chloroaluminates far more effectively than Portland cement pastes Lower permeability limits ingress of chlorides At 50% and greater, diffusivity of chloride ions becomes insignificant - Substitution levels of 70% to 80% often used To prevent the penetration of chloride ions a dense, impermeable concrete needs to be produced. This can be achieved by using Ground Granulated Blast furnace Slag (GGBS). When GGBS cement hydrates, dicalcium silicate and tricalcium silicate are formed. However, the reaction also produces other secondary hydrates, which effectively fill the cement paste pores. This is because there is an excess of reactive alumina and silica in the material. Both these compounds are free to react with the excess calcium hydroxide, which is present in the pores of cement paste to form further calcium silicate and calcium aluminate hydrates. These block the pores and reduce the permeability of the cement paste. In addition, GGBS cements are able to bind the penetrating chlorides into chloro-aluminates far better than cement pastes containing pure Ordinary Portland Cement or Sulphate Resistant Portland Cement. This reduces the danger of chloride attack still further. Sulphate Resistant Portland Cement has a reduced binding ability because of the low tricalcium aluminate content. GGBS cement has a slower rate of hydration than Ordinary Portland Cement helps in reducing the permeability of concrete as cracking due to temperature rise is minimised.

    • 1. September 2009 Ecocem Ireland Ltd
    • 2.
      • Long term agreement with partner companies for supplying high quality GBS
      • Can supply the Irish market with over 350,000 tonnes from Dublin
      • Provide technical back up to specifiers and concrete manufactures
    • 3. Steel Manufacture Water to make GBS GBS Grind to make GGBS Store GGBS for distribution
    • 4.
      • GGBS cement, and OPC
    • 5.
      • 50% GGBS
      • 50% OPC for durability
    • 6.

      • Properties & Advantages of using GGBS
    • 8.
      • Stronger
      • Longer life
      • Less cracking
      • Increased resistances to:
      • Acid Attack
      • Chloride (salt) attack
      • Sulphate (brown field site) attack
      • To fire

      • Environmental Advantages of using GGBS
    • 13.
      • A rise of 1 metre in ocean levels will displace 35 Million people in Bangladesh.
      • Conflict in Darfur is directly linked to Climate Change
    • 14.
      • Cement manufacture:
      • Significant source of industrial CO 2
      • Releases harmful pollutants
      • Significant energy user
      • Depletes natural resources
    • 15.
      • CO 2 emissions for Ecocem GGBS and cement production
    • 16.
      • Environmental savings example
      • What is the impact of replacing 50% of cement with GGBS in an average size shopping centre, using 5,000m 3 of concrete?
      • See calculator on:
      • www.lowcarbonconcrete.ie
    • 17.
      • Albedo Effect – measure of solar reflectivity
      • Concrete pavement v’s macadam pavement
        • For every 15m 2 of Ecocem concrete surface the increased solar reflectivity will save 1 tonne of CO 2 every year
        • A 100m 2 paved area to a house makes the same contribution as leaving your car at home for 2 years
    • 18.
      • Sustainable development is "development that meets the needs of the present without compromising the ability of future generations to meet their own needs"
      • Recycled by-product – No new raw materials used
      • Durability – Longer life span
      • Significantly Lowers CO 2 Emissions in construction
      • Reduces global warming throughout its entire life
      The most sustainable building material in the world.......
    • 19.  
    • 20.
