PHOENIX

Portland-Fly Ash Cement (CEM II/B-V 42,5N)

A factory manufactured Portland-fly ash cement.
Suitable for:

• Large pours, to reduce the risk of early-age thermal cracking.

• Reducing attack on concrete in sulfate conditions.

• Improved surface finish of concrete.

Benefits

  1. Quality

    Quality assured CE Marked product.
  2. Lower CO2

    Lower embodied CO2 than CEM I Portland cement
  3. Easy Ordering

    Single point ordering (compared to using separate ash and Portland cement)
  4. Resistance

    An enhanced resistance to sulfate and chloride ingress.
  5. Reducing Alkali risk

    Reduces risk of Alkali-Silica Reaction.
  6. Time-saving

    Reduced mixing times (compared to using separate ash and Portland cement)
  7. Improves pumpability

    Improves pumpability
  8. Strength

    Strength gain after 28 days.

Case Studies

Cement

Whitelee Wind Farm, Scotland

Tarmac Cement has played a vital role in the construction of Europe’s largest onshore wind farm – which can provide enough green energy to power nearly 300,000 homes.

Technical information

Phoenix is available in bulk tankers throughout the United Kingdom. 

Properties:

Phoenix Portland-fly ash concrete – when compared with Tarmac bulk Portland cement concrete at the same cement content – has the following properties:

• Slower strength development and potentially higher long-term strength.

• The appropriate cement content for concrete of a given 28 day cube strength and slump should be determined from trial mixes.

• The cement content may differ from that of an equivalent Portland cement (CEM I) concrete in certain circumstances. In particular, where a high strength concrete is required, the cement content may be slightly higher than for CEM I.

• Slower setting times.

• Reduced water demand.

• Improved placing and finishing.

• Darker in colour

  • Phoenix® Portland-fly ash cement conforms to BS EN 197-1 CEM II/B-V 42,5N.

Conditions of Use:

  • Concrete, mortars and grouts containing Portland Cements must be specified and used correctly for best performance.
  • The cement content must be correct and the water: cement ration as low as possible consistent with satisfactory placing, thorough compaction and effective curing.
  • The final finish quality of this material will depend upon the operative having the required skills and a familiarisation with the materials and its application methods.
  • Tarmac cannot be held responsible where workmanship has not been carried out in accordance with good practice.
  • Phoenix is manufactured from natural products, and slight shade variations may occur. Ferrocrete will also have shade variations from differing manufacturing centres.
