Read our article below to learn more about the differences and benefits of constructing with cinder and concrete blocks.
If you are looking into building a house or buying a ready-made structure, chances are you need to decide on what material to use for it.
Your new house can be constructed of a number of different materials; each material has its own benefits and shortcomings.
Some are stronger, some are cheaper and some are more eco-friendly. Either way, a decision has to be made as to which one works best for you.
Though you need to choose which construction material is best for your house, chances are you won’t be choosing just one.
In almost every house, these materials are used in conjunction to create the final structure. Some of these materials include glass, wood logs, plastic, clay bricks, cement, metal and of course, cinder and concrete blocks.
Cinder blocks and concrete blocks are often seen as interchangeable, but the blocks do have some fundamental differences. To know more about them, read below:
How Are Blocks Used In Construction?
These blocks are used as the primary construction material in walls. These blocks are often referred to as concrete masonry units (CMUs). These blocks are one of many other materials that work in unison for construction.
Concrete and cinder blocks are precast materials, meaning that their structure is formed away from the job site; they are hardened and then brought in for construction.
Concrete and cinder blocks are used in buildings or double-story houses to reduce structural load. The blocks are a much lighter alternative to bricks.
A typical block is also about 6 times the size of a brick, measuring to 60cm x 25cm x 15cm.
These blocks are laid together and bound by concrete, then layered in the same fashion as bricks. The layering is done vertically until the desired height of the structure is achieved. The process is repeated to form the skeleton of the structure.
What Are Cinder Blocks?
Cinder blocks are typically made of concrete and coal cinders, but in reality, they can be made of many different things.
The term “cinder block” has become a generic synonym for any structural block, but they need to be produced with cinders. Cinder is the ash left behind when materials like coal or wood are burned.
These blocks often feature two or three cut-outs in the center, creating a hollow rectangular shape. Because of the way they are structured, and the way they are created, cinder blocks are more lightweight when compared to their counterpart.
However, because of this, they aren’t as strong or structurally sound either. If you live in an area with a lot of humidity or moisture, cinder blocks should be avoided as much as possible because they are prone to bowing and buckling, and repairs in the foundation can be very expensive.
Traditional cinder blocks have become an outdated material for construction and can hardly be found on any site.
This is because the blocks lack tensile strength and are not easily replaceable. When we talk about actual cinder blocks, not the generic term, they haven’t been as produced in over 50 years; if they need to be replaced, they are not as readily available.
What Are Concrete Blocks?
Concrete blocks are traditionally made of pure concrete; an aggregate of crushed stone and sand. These days, concrete blocks have steel, wood or cement mixed in to increase structural integrity.
These blocks are heavier and stronger than cinder blocks. These blocks can withstand a lot more pressure as well; making the structure they are used in much more sound and reliable.
If the structure is not too high, and cost-efficiency is a factor, people tend to use concrete blocks along with cinder blocks alternately so they don’t lose much structural integrity but save on cost.
Concrete is a durable, heavy and long lasting material, which makes it a popular choice for construction. The blocks are also a lot larger in size compared to bricks, making them preferable for use in taller buildings.
With all the facts above, it makes you think that concrete is the far superior choice for construction, so why do people still use cinder?
It’s true; a lot of building codes explicitly prohibit the use of cinder blocks in construction projects because of its weak structural integrity and low tensile strength.
But somehow, whenever it is permitted, construction workers use cinder blocks in their projects.
The fact of the matter is that cinder is a lot lighter, making it much easier for workers to construct, rather than having to lug around heavy concrete blocks.
Over time, because of their lack of availability and preference for use by construction workers, cinder blocks are becoming more and more expensive; even though they lack tensile strength.
We hope this breakdown of the two construction materials makes your understanding and choice a little bit easier!
