What are cinder blocks?

Cinder blocks are a common construction material made from concrete and cinder. They are used to create walls, foundations, and other structures. Cinder blocks are often painted or covered with stucco to improve their appearance.

Cinder blocks can also be used for gardening to create raised beds.

Cinder blocks vs Concrete blocks:

Although people use both the term interchangeably there is a subtle difference between them.

Initially, cinder blocks were commonly made from ash, and that’s where the term comes from. But now, cinder blocks are mainly made out of concrete. True cinder blocks are pretty rare. 

So when we talk about cinder blocks we actually mean concrete blocks. This is very important as true cinder blocks can leach chemicals into the soil, so it is not a recommendable product to use for growing plants. 

Current cinder blocks or concrete blocks don’t have these problems and are totally safe to use in the garden.

So please remember, whenever in this post we talk about conder blocks we actually mean concrete blocks.
