Mixes

A guide to the different types of concrete and screed.

  • C8 (Gen 0/18_1)

    For kerb bedding and backing.

  • C10 (Gen 1/16_1)

    For blinding, mass concrete fill, un-reinforced strip, trench fill and pad foundations, over-site below suspended floors, and drainage works.

  • C15 (Gen 2/15_1)

    For house floors with no embedded metal.

  • C20 (Gen 3/ST 1/12_1)

    For internal floor slabs.

  • C25 (ST 2/11_1)

    For footings/foundations and groundwork.

  • C30 (PAV1/ST 3/9_1)

    For light use external slabs, e.g. outdoor paved areas such as driveways, paths, patios, garages, carports and pavements.

  • C35 (PAV2/ST 4/7_1)

    For heavy-duty use external slabs/piling, e.g. external paved areas subject to the constant loading and scraping imposed by industrial vehicles and machinery.

  • C40 (ST 5/5_1)

    For structural beams and agricultural use.

our concrete, it's 'ard!

As a guide, here are some common terms for different types of concrete and screed and what they are used for – we can deliver all of these mixes.

Plasticiser – to soften the mix before it hardens, increasing its workability; this is not intended to affect the properties of the final product after it hardens. Our plasticisers offer the following advantages:
Concrete Fibres – are an alternate system to traditional reinforcement when used for secondary (crack control only) reinforcing in concrete. They improve resistance to intrinsic cracking, improve water tightness and offer an aesthetic finish. Our fibres offer the following advantages:
  • Improved workability/reduces water/cement ratio
  • Flexible high performance plasticiser
  • High resistance to segregation/reduces bleeding
  • Improved surface finish
  • Reduces shrinkage cracking potential
  • Higher initial and ultimate compressive strengths
  • Higher durability concrete
  • Multi functional
  • Excellent slump retention
  • High early strengths
  • Rheology improver
  • Reduces plastic shrinkage and settlement cracking
  • Reinforces against the effect of shattering forces
  • Inhibits and controls the formation of intrinsic cracking in concrete
  • Reinforces against water migration
  • Reinforces against impact forces
  • Provides improved durability
  • Reinforces against abrasion
  • Provides freeze-thaw resistance
  • Inhibits explosive spalling
Retarder – Our Retarder is formulated from phosphates which temporarily stop the chemical hydration of cement. It allows the production of retarded concrete with increased ultimate strengths. Our retarder offers the following advantages:
Screed Fibres – these add tensile strength to produce reinforced concrete. Our fine fibrillated fibres contain no reprocessed olefin materials. They are specially engineered for use as reinforcement in screed. They are non magnetic, rustproof, and alkali proof. Our fibres offer the following features and benefits:
  • Accuracy of retardation
  • Long haul problems solved
  • High resistance to segregation/reduces bleeding
  • Higher initial and ultimate compressive strengths
  • Higher durability concrete
  • Provides increased early stage strength
  • Increases cohesion and reduces segregation
  • Reduces settlement and bleeding
  • Inhibits and controls the formation of intrinsic cracking in concrete
  • Reduces plastic shrinkage and settlement cracking
  • Increases impact and shatter resistance
  • Reinforces against abrasion
  • Reduces freeze/thaw damage
  • Provides improved toughness / durability
  • Provides residual strength
