Types Of Concrete & Their Strengths

There are plenty of different purposes people have for concrete; it can be used for foundations, flooring, walls and more. But not every concrete mix is the same, and depending on what you are aiming to achieve, you need to get a concrete mix that is fit for purpose.

Concrete mixes can use a number of materials to give different qualities. Generally, they all include cement, water and some mixture of sand and stone.

At The Concrete Network, we provide a variety of concrete mixes tailored to commercial and domestic purposes. We can advise you on which type of mix is best for your project if you contact our team, and we can even tailor a mix to your exact requirements.

What is it used for?
  • basement builds
  • larger work sites
  • anywhere time and space is short

Volumetric Concrete

What is it used for?
  • multi site projects
  • basement builds
  • large sites

Self Compacting Concrete - SCC

Self Compacting Concrete - SCC

Characteristics: This mix has chemicals added for a quicker flow rate, this allows it to level off and self-compact. This concrete is easy to pour into place without the need for mechanical compaction.

What is it used for?
  • foundations
  • pre-cast structures
  • sites with limited time and labour

Decorative Concrete

Decorative Concrete

Characteristics: You can achieve a whole range of colours and textures through decorative concrete. This makes it ideal for any projects where you’re looking to make an aesthetic impact.

What is it used for?
  • decorative flooring
  • paving
  • architectural features

What is it used for?
  • concrete repair
  • roadworks
  • fence posts

Roll Compacted Concrete

Roll Compacted Concrete

Characteristics: With the ability to carry heavy loads, this concrete is ideal for roads. It requires less finishing and formwork and is deployed in a similar manner to asphalt. There are less emissions created when it is produced, providing environmental benefits.

What is it used for?
  • pavements
  • roadworks
  • airport taxiways
  • car parks and industrial surfacing

Fibre Concrete

Fibre Concrete
