What are Cinder Blocks Made of?

Cinder blocks are made with a mixture of concrete and slag material. That’s why they also get the name slag blocks. Different slag materials are used today to make cinder blocks. They are called fillers. Such fillers can be:

  • Broken Glass.
  • Gravel.
  • Crushed Granite.
  • Expanded Clay, etc.

How Much Weight Can Cinder Blocks Withstand?

It depends on a number of factors. If the cinder block is used in a wall, the height of the wall will determine the weight it can hold.

According to ASTM C90, a hollow load-bearing concrete masonry unit should have a compressive strength of 1900 psi. This compressive strength determines the amount of weight a block can withstand.

An eight-inch block is 50% solid. So, if I did the math right, it would be able to withstand 120,000 pounds. Much less weight is put in reality. This is for maintaining the building’s safety.

How Much Does a Cinder Block Cost?

According to data from 2024, the average cost of a standard cinder block can range from $1-$3 for each block. The actual cost depends on a number of things.

The block size is also a key factor. We’ve already seen how the blocks vary in size and style. So, we can understand the difference in the price of cinder blocks.

Cinder Block Cost Summary

The place where you live will have an effect on the cost of your cinder block. The availability of cinder blocks in your geographical location will determine the cost to a good extent.

The vendor you are buying from is also something to be considered. A vendor will adjust the price according to market conditions. So, the overall supply chain and market demand will determine the actual price.

The block style is also something to be considered. Different styles of blocks are used in different projects. So, the type you are using will determine the money you spend.

  • Cinder blocks are heat resistant. This increases the safety of your construction by reducing fire-related risks.
  • Weak thermal conductivity causes the construction to be cooler than usual.
  • Easy construction process. The projects using such materials are completed fast. The duration is not that big.
  • There is a wide range of solutions that you can find. Cinder blocks offer a variety of geometric solutions to the project.

3 Major Disadvantages of Using Cinder Blocks

Using cinder blocks has a few disadvantages, which are listed below.

  • A cinder block is costly to maintain. People have spent more money on repairing and maintaining the cinder blocks. This increases the overall cost of the project.

(Height × Width × Length) × 2400

Formula, 2022

 Because the Density of concrete is 2400 kg per cubic meter.

Now I’m answering the most common question that people also asked about (Cinder Block Weigh): FAQ

Which one is stronger? Cinder blocks or concrete blocks?

The average concrete block is stronger than the average cinder block. They are able to withstand more weight. They are heavier and more durable. They don’t have to be repaired much.

Why do some cinder blocks weigh more than the others?
