اقرأ أكثرConcrete And Cement Dust Health Hazards
Fine cement and concrete dust can land on exposed skin, and get trapped between loose clothing and skin. The dust reacts with sweat or damp clothing to form a corrosive solution, which will damage your skin. Wet cement is highly alkaline. A serious burn or ulcer can rapidly develop if it is trapped against the skin.

Silica dust can cause silicosis, a serious and irreversible lung disease. It can also cause lung cancer. Cutting, breaking, crushing, drilling, grinding, or blasting concrete or stone releases the dust. As workers breathe in the dust the silica settles in their lungs.

Breathing crystalline silica dust can cause silicosis, which in severe cases can be disabling, or even fatal. When silica dust enters the lungs, it causes the formation of scar tissue, which makes it difficult for the lungs to take in oxygen. There is no cure for silicosis. Silicosis typically occurs after 15–20 years of occupational exposure ...

The dangers of inhaling concrete dust and stone dust should never be played down. Dust from both can carry high volumes of silica, which can travel into your lungs and cause scar tissue or cell necrosis.

Concrete dust contained more than 30 wt.% of crystalline silica, while cement paste had very little crystalline silica. Most of the silicon in the cement paste was in the form of calcium silicates and in compounds such as thaumasite, lamite, and alite. Cement dust contained more than 35 wt.% of calcium hydroxide in the crystalline phases.
