Concrete Irritation, Burns, and Dermatitis

Oct 26, 2021Irritation is caused by the skin's exposure to concrete and, more specifically, its aggregate material makeup. This is because concrete includes a binder ingredient called Portland cement, which is also found in mortar, plaster, grout, and more. When wet, uncured Portland cement reaches caustic pH levels of 12 or higher, compared to the skin
