Cement Extraction and processing | Britannica
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.

How to Rapidly Speed up Concrete Drying Time
How Long Does Concrete Take to Dry? According to the Portland Cement Association, once conditions are conducive for the concrete to dry — that is, consistent, reasonable heat in the air and low relative humidity — it typically takes about 30 days for every one inch of slab thickness to dry to 8590% relative humidity. We say ''once conditions are conducive'' because concrete that was put
