Is breathing concrete dust harmful?

When materials such as concrete, stone, brick, or granite are cut or ground by workers, it can create extremely fine dust particles, which can make their way deep into the lungs if inhaled. These silica dust particles can cause scarring in the lungs, leading to a serious and irreversible lung condition known as silicosis.

Is concrete dust harmful?

The most problematic component of dust and fines from concrete are silicates, which pose health risks if inhaled. Repeated or chronic exposure may result in silicosis, which is bad. The dust will also contain calcium hydroxide and will be quite alkali, so it has other components that will irritate skin, eyes and mucous membranes.

Many people working in the cement or construction industry usually suffer from cement poisoning and cement burns on skin. It occurs due to the reaction of toxic and chemical constituents present in cement, which can also cause respiratory problems.

Why make concrete blocks?

Another benefit to making your own concrete blocks is that you can vary the shape however you like. Blocks are designed for building foundations, not garden beds, so the shape can be changed. I like to remove that center piece of cement located in the middle of the block. This creates one big opening that I can fill with soil and plant. That center strip is there to strengthen the block for foundation work but gardens don’t need to support tons of weight so it’s unnecessary.
