What are cinder blocks made from? When you burn coal or wood, it leaves behind a residue we call ash or cinders. To make cinder blocks, you combine these cinders with cement. The result is a lightweight, hollow and sturdy block.
How Are Cinder Blocks Made?
Cinder blocks, also known as concrete masonry units, are a popular building material used in a variety of construction projects.
They are made from Portland cement, fine aggregate, and larger aggregate such as sand or gravel. The blocks are usually formed in a mold and then cured with steam or air.
Cinder blocks are a versatile and durable material that can be used for a variety of applications including walls, foundations, and patios.
The process of making cinder blocks begins with gathering and mixing the raw materials. Portland cement, water, sand, and gravel are combined in a mixer and combined until a homogenous mixture is achieved.
The mixture is then poured into molds and allowed to set. During this stage, the mixture is compacted and vibrated to ensure that the blocks are properly formed.
After the blocks have been set, they are dried and cured. This is done by either air–drying or steam–curing them. Air–drying is the most common method used for small–scale production, while steam–curing is used for larger scale production.
Air–drying cinder blocks is done in climate–controlled rooms, while steam–curing is done in industrial–sized ovens. Once the
