Concrete Types
Many people think concrete is just concrete, a standard grey wet workable material that then sets, unfortunately it isn’t that simple.
There are many different types of concrete, strengths and uses which are always evolving so please call to discuss your project and requirements as we can always find a solution.
Below is just an example of a few different mix types and uses:
- Pump mixes these generally need more sand and cement to make them pumpable
- Footing mixes mixes designed for groundwork trenches
- ST mixes ideal for Kerbs trenchful etc…
- RC mixes desired mix for when strength and durability is required
- Waterproof mixes ideal for basements and swimming pools
- Gen mixes general purpose mixes used in domestic and commercial projects
We can also add any of the below admixtures
Plasterciser
If you are needing more flexibility, plasterciser will soften the mix, allowing greater dexterity if used before the mix hardens. Plasterciser also reduces bleed and cracking and more unlikely to split, improving the finish.
Retarder
Using retarder will allow the concrete to be a lot more substantial. It does so by temporarily blocking chemical hydration. This will also reduce the prospect of bleeding.
Concrete Fibres
Concrete fibres are an alternative to tradition use. It will decrease cracking and increase water resistance, whilst settling with a nice finish.
Screed Fibres
Using screed fibres will increase strength and durability of the mix. Extremely tough, you will find that the chances cracking, shrinking and bleeding have been reduced.
Additives
A vast amount of applications can be suited with additives now varying from waterproof agents to water reducing agents and foam mixes to name a few, contact us for any additives required.
Concrete Mix Types
C7/8 / Gen 0
C7 & 8 concrete mix, Gen 0 concrete or wet lean mix concrete, is commonly used in both commercial and domestic projects for a huge range of general applications, such as kerb bedding, haunching and backing, domestic foundations and blinding.
Ideal for: Cavity filling, kerbing, domestic foundations & haunching. Strength: 7 Newton/28 day strength.
Strength: 7 Newton/28 day strength
C10 / Gen 1
C10 concrete, or Gen 1 concrete is an extremely versatile mix used throughout the construction industry for general and housing applications.
This includes un-reinforced strip, trench fill and agricultural applications.
It can also be used for drainage works and blinding house floors, as well as pad foundations and non-structural mass concrete in non-aggressive ground conditions.
Ideal for: Foundations for steps, trench fill, floor blinding & drainage works.
Strength: 10 Newton/28 day strength.
C15 / Gen 2
C15 concrete or Gen 2 concrete is suitable for house floors with no embedded metal.
It also provides the ideal material for flooring when no permanent finish or floor covering will be installed, such as carpet or tile.
Ideal for: Foundations for small walls, sheds & conservatories. Paving for steps and paths.
Strength: 15 Newton/28 day strength.
C20 / Gen 3
C20 concrete mix and Gen 3 concrete is commonly used for lightweight domestic applications and foundations, such as driveways and garage, shed & workshop bases.
It can also be used to construct internal floor slabs so long as they contain no embedded metal.
Ideal for: Foundations for large walls, garages, houses & extensions. Paving for patios. Reinforced bases & oversites for conservatories, garages, sheds, greenhouses.
Strength: 20 Newton/28 day strength.
C25 / ST 2
C25 standardised mix concrete or ST2 Concrete is widely versatile and used in numerous commercial and domestic projects.
It is commonly used for footings and foundations, including mass concrete fill, trench fill and reinforced fill, as well as general groundworks.
It can also be used for kerbing, infilling around manholes and small bases for external furniture, such as patios.
Ideal for: Foundations and reinforced bases for houses & extensions. Trench fill, kerbing & patios.
Strength: 25 Newton/28 day strength.
C30 / PAV1 / ST 3
C30 concrete, PAV1 concrete and ST 3 concrete are the most common types of concrete used for pavement construction.
It is also ideal for lighter use external applications, such as slabbing, as well as outdoor paved areas such as stables, driveways, walkways, patios and garages.
PAV 1 mixes have an air entrainment additive to create standard sized air bubbles in the concrete. This helps to protect the surface from freeze-thaw cycles, making it especially useful for outdoor paving.
Ideal for: Paving external kennels and reinforced hard standings. Reinforced bases for workshops and unreinforced bases for houses & extensions.
Strength: 30 Newton/28 day strength.
C35 / PAV2
C35 concrete and PAV2 concrete is a heavy-duty use concrete.
It offers high quality similar to PAV1, but is much more substantial making it suitable for commercial and industrial use.
Common applications include raft foundations, piling and external slabbing and pacing that will be subject to the constant loading and scraping imposed by industrial vehicles and machinery.
PAV 2 mixes have an air entrainment additive to create standard sized air bubbles in the concrete. This helps to protect the surface from freeze-thaw cycles, making it especially useful for outdoor paving.
Ideal for: Reinforced bases for commercial buildings and agricultural light storage areas.
Strength: 35 Newton/28 day strength.
C40
C40 concrete is a strong commercial grade concrete mix
Most commonly used in the construction of structural and support beams, footings and foundations, roadworks, and in agricultural use.
Ideal for: Foundations for septic tanks, paving HGV parks and agricultural yards.
Strength: 40 Newton/28 day strength.
