Types of Concrete

If you need concrete but don’t know which type, then find out what Pez has to offer. With a range of different grades and strengths, we have what you need.

Concrete is not a one size fits all material, and you need to get the right type for your project if you want the best finish. Here at Pez Concrete and Liquid Screed, we offer a wide range of concrete and are on hand to help you work out the type you need.

The Different Types of Concrete

The majority of concretes are made from water, cement, and an aggregate like sand or stone. However, the ratios of the materials can be changed to produce different results depending on what your needs are. We can also add additional materials into your concrete mix to produce a specialist mix. Broadly, concrete can be sectioned into multiple types including designated, designed, standard prescribed and proprietary – all of which can also be graded differently for the different uses.

1. Proprietary Concrete

If a traditional solution to concreting is not going to work for your individual needs, then a proprietary concrete can be created to serve a bespoke solution. Producers can blend together a number of ingredients to get the desired outcome such as a specific colour, higher strength, resistance to certain chemicals or even fast or slow setting.

2. Standardised Prescribed Concrete

Usually mixed just before pouring on site, these are best for smaller jobs and have been given no guarantee of strength, however they are made with certain quantities of elements as described in BS 8500.

3. Designated Concretes

These are designed to make choosing your concrete style simpler, and even though they are not able to be used in many residential or commercial applications, they still serve a purpose in some settings where strong concrete is required. The producer of this type of concrete needs to hold a certification, and the buyer can choose their concrete based on what purpose it will be used for rather than having to check the limits of strength and stability over time in larger builds. These types of concrete can be broken down into 4 groups:

General

largely for non-structural uses, no specific cement-water ratios needed

Reinforced Concrete

for use where the concrete will be used in conjunction with steel rods to stabilise the structure. There has to be strict requirements for the concrete-water ratio and minimum content of cement to ensure its durability. It can be used for numerous applications and is tough enough to cope with weather conditions outside, and there are 6 types to choose from:

Paving Concrete

designed for outdoor use and can cope with hot weather as well as freezing and thawing, this concrete is widely used for the majority of external applications such as when durable hard standings are needed, for roadworks and pavements. These concretes do have to adhere to minimum concrete content and concrete-water ratio, but they also have to be created to have a certain amount of air, which of course will vary according to the aggregate used.

Foundation Concrete

if the ground contains sulfates, then this is the special type of designated concrete needed to create the foundations. It is made with a specific concrete-water ratio and has a strong resistance to soil containing chemicals such as sulfates which could impact the strength and composition of the concrete.
