Types Of Concrete And Their Strengths

Finding the right type of concrete for your project is essential for getting the best results. Here at EasyMix Concrete we design and supply a huge range of concrete strengths and grades to ensure the ideal solution for any project or application.

Concrete Mixes

Most concrete mix designs use the same type of raw materials: cement, water and aggregate (usually sand and stone), in different ratios. Some types of concrete have additional materials added to give specialist qualities, such as:

  • Fibres – enhanced strength
  • Plasticisers – free flowing, better workability
  • Retarding agents – reduce rate of setting
  • Accelerating chemicals – increase rate of setting
  • Corrosion inhibitors – reduce corrosion of steel rebars 

Have a look through our glossary of concrete types to make sure you get the right concrete for your project. If you’re not sure, or would like to discuss you requirements, simply give the team at EasyMix a call. Even if we can’t supply the exact type of concrete you require, we’ll be more than happy to discuss your project, recommend alternatives and ensure you get the right materials for the best results.

Glossary of Commercial Concrete 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.

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 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.

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.

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.

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.

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.

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.

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.
