Additional information
Respirable Crystalline Silica (RCS) may cause cancer. Concrete is a mixture of gravel or rock, sand, Portland cement and water. It may also contain fly ash, slag, silica fume, calcined clay, fibers (metallic or organic) and color pigment. Properties and composition of crushed concrete can vary depending on the original properties and composition of the recovered concrete. Natural sand includes quartz, a form of crystalline silica. Material may contain small percentages (less than 15%) of glass, porcelain or other ceramic materials. Crushed concrete may be subjected to various natural or mechanical forces that produce small particles (dust) which may contain respirable crystalline silica (particles less than 10 micrometers in aerodynamic diameter). Repeated inhalation of respirable crystalline silica (quartz) may cause lung cancer according to IARC and NTP; ACGIH states that it is a suspected cause of cancer. Other forms of RCS (e.g., tridymite and cristobalite) may also be present or formed under certain industrial processes.
