Which Is the Strongest Concrete Block?

Which Is the Strongest Concrete Block?

There are many types of concrete blocks available to use as a solution in construction. Generally, you want your concrete block to be strong, especially if it’s going to be in an environment where it could receive impact.

In this blog, we will answer the question ‘Which is the strongest concrete block?’

At PPC Concrete Products, we are here to provide solutions for your construction needs, from the person working their own part-time project, to commercial clients, and everyone in-between.

Monthly construction output had risen an estimated by an 1.6% value in June 2023, and we would like to think our accessible concrete products had a small part to play by giving our clients easy access to reliable and easy-to-use construction solutions.

Why is strength important for building materials?

How much does it cost to make a retaining wall?

Materials that are used in building structures, such as bricks, blocks etc must be strong, as the structures that they create collectively weigh a lot. Using a building material that is weak in nature can compromise the whole structure.

Building materials that are strong must firstly be able to support a large amount of weight collectively. Furthermore, having a level of durability means that the structure isn’t at risk of collapsing should there be any impacts. This is not guaranteed with a weak building material.

Can concrete blocks be made on site?

To make an industrial standard concrete block, the equipment, storage, and precision required may be a bit difficult to achieve on a building site. However, you may be able to make some.

Here is what you need to make a concrete block on site…

  • The ingredients to make the concrete.
  • The moulds to pour the concrete in to.
  • A dry space to store the moulds.
  • The equipment to manoeuvre the blocks safely.

Creating a concrete block on a building site is achievable, but whether it will be of an industrial standard quality is another question. Expediting the process by seeking the services of a concrete block manufacturer is the safest and least time-consuming method.

Is it more expensive to build your own concrete blocks?

If you aren’t an expert, who also has the equipment and space necessary on hand, then yes. It will be more expensive to build your own concrete blocks from scratch.

Which is the strongest concrete block?

Which Is the Strongest Concrete Block?

We believe that our Interlocking Concrete Blocks are the strongest concrete blocks you can use. But why exactly is this? Let us explain. We define the strength of a concrete block through the following factors…

  • Durability
  • Stability
  • Resilience

Here is how our concrete blocks tick the boxes that we use to define its strength.

Durability and concrete generally go hand in hand. Concrete is durable by nature and can sustain impacts of varying degrees with little to no side effects. Our Interlocking Concrete Blocks are not hollow either, this means you’re getting even more durability than you would get with a hollow concrete block.

Stability is also a natural by-product of our Interlocking Concrete Blocks due to their heavyweight nature. This is further reinforced once the blocks are interlocked with each other. This is achieved through the studs and recesses located at the top and bottom of the blocks, respectively.

Interlocking the blocks can be achieved with no binding materials whatsoever. The resulting structure has its weight evenly distributed, meaning it is next to impossible to topple over naturally.

In regard to the weight of the blocks, it will vary from size to size, and from the concrete being used. But as an example, 1800 × 600 × 600 concrete block can weigh 1560 kg, this can fluctuate as different types of concrete have different levels of density.

The resilience of our Interlocking Concrete Blocks is again facilitate by natural characteristics of concrete, specifically, resilience against weather. There is no kind of weather that can affect or weaken our Interlocking Concrete Blocks. It is fire-resistant, indifferent to heat, rain or snow, making it perfect for outdoor uses such as a material for a retaining wall.

What can make a concrete block weak?

Concrete blocks can be weak depending on their production process. If the incorrect ratio of ingredients is used, this can result in the blocks being weaker. Additionally, not allowing the blocks to dry completely further contributes to having a weaker block.

How high can interlocking concrete blocks be stacked?

Our interlocking concrete blocks have the potential to have 5 blocks stacked upon each other. Our standard-sized blocks are 60 cm in height, with 5 stacked together this would equate to 300 cm, which is exactly 9 feet (2.74 m) & 10.11 inches (25.68 cm) high. This height is more than enough for applications such as a retaining wall and so much more.

Can you get Interlocking Concrete Blocks from batch plants?

Can you get Interlocking Concrete Blocks from batch plants?

It may be rare to find a batch plant that creates concrete blocks, never mind ones that interlock. A batch plant would need additional space to house the concrete block moulds, as well as dedicated vehicles to transport them. Most, if not all batch plants, generally use vehicles that transport wet concrete, not dry. Though there may be exceptions to this.

For those who are unfamiliar, a batch plant is a specialised site dedicated to the production of concrete of various grades. If concrete is made in a batch plant, it is made to the specific requirements of the customer. Industrial and smaller jobs can receive concrete from a batch plant.

What can I use Interlocking Concrete Blocks for?

Here is a list of some of the uses that Interlocking Concrete Blocks can facilitate.

  • Material Storage bays
  • Blast walls
  • Salt stores
  • Crash protection
  • Push walls
  • Security barriers
  • Segregation bays, i.e. recycling centres
  • Retaining walls
  • Industrial buildings
  • Fire breaks
  • Counterweights
  • Roadblocks

What’s the cost of Interlocking Concrete Blocks?

Pricing of our Interlocking Concrete Blocks is entirely dependent on your needs. To provide an accurate quote, we require as much information as you can provide about what you require the blocks for.

From this, we can estimate how many you require, and which sizes of would be best suited for you. Don’t hesitate to contact us directly if you have any questions you would like to discuss directly regarding our concrete products.

What can dislodge Interlocking Concrete Blocks?

Find the best concrete blocks today

Interlocking Concrete Blocks can be dislodged by lifting the block from the stud it was placed on. This gives Interlocking Concrete Blocks a chance to be reused should that be required. Aside from this, a significant impact has the possibility of dislodging Interlocking Concrete Blocks, but this is subject to the amount of blocks that have been stacked, and the cause of the impact.

Aside from that, there is no natural means that Interlocking Concrete Blocks can be dislodged aside from a natural disaster, or other freak weather occurrences/ high velocity impacts.

Although you generally don’t make structures with the assumption that they’re going to take impact regularly, it does help to have some level of preparation just in case that ever happens. That is why Interlocking Concrete Blocks are such a worthy investment.
