KGS--Geological Log Analysis--Evaporites
Gypsum is easily recognized by its low gamma -ray value, very high neutron porosity exceeding 60 (due to the hydrogen contained in its water of crystallization) and density of 2.35 gm/cc. The gypsum beds of the Blaine Formation are obvious on the example log section, and can be distinguished immediately from anhydrite, which has a neutron ...

gypsum plaster vs cement plastering
Reduce Construction Time by 75%. Gypsum Plastering has faster setting time than cement plastering. The gypsum walls are paint ready in 4 days compared to 15 days with cement sand plastering. Sand cement plastering needs at least 15 days to reach the inherent properties, whereas gypsum gains its inherent properties within 48 days of application.
