cement - cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
Concrete grinding produces silica dust. If the dust is breathed in over a period of time, it can lead to a disease called silicosis or scarring of the lungs. This was such a common problem for grinder operators in years past that one of its common names was 'grinder's asthma'.
