Dec 01, 2019 The exploited gypsum belongs to the lower part of the first gypsum unit (PLGPrimary Lower Gypsum unitFig. 1b) which is organized in four thick gypsum layers alternated with marl layers. The relevant thickness of these gypsum layers allow an effective exploitation. At their top, the unit presents a more dense alternation of gypsum and marl.
The lightweight aggregate is gypsum1. Gypsum1 has been obtained through the mining process. Continuous exploitation of mining materials4,5,7,8,12,13,14 makes the quantity of minerals less and can have an impact on the environment. Given the current mining situation the use of construction3,4,5,6,7,8 materials should be done effectively.
