2016-8-19 · The short answer is "no". PRO CAL 40 is one of the most pure forms of gypsum you can buy and the particle size is very small (<160 microns) so granulized gypsum has no advantage over PRO CAL 40 other than it can be spread at lower rates easier and can be mixed with other granulized fertilizer materials. Since PRO CAL 40 is less than $20 per ...

2019-12-30 · The crystal appearance changed significant with the addition of SL. The length-radius ratio of gypsum crystal decreased and thus bulky and granular gypsum crystal were observed in samples B2 and B3 which were well crystallized but with no interlocking between each other. This is the reason responsible for the much lower strength even with ...
Gypsum is one of the most important salts in the deterioration of building materials and, particularly, wall-paintings. Objects exposed to exterior conditions where air pollution is present are the most prone to damage from gypsum. The appearance and mechanism of the damage, as well as the examination methods are described.

appearance makes it rather easy to distinguish from all other rocks. It is composed of the elements that make quartz, feldspar and iron/ magnesium minerals that have cooled so quickly that the minerals could not develop and crystallize. Colors vary from black to red, black & red (mahogany), gray, green, iridescent, snowflake.
The Chinese name of the largest of the collapse dolines is "tiankeng." A tiankeng is a collapse doline at least 100 m long, wide and deep, and with perimeter walls that are close to vertical (Zhu and Waltham, 2006).The greatest of these depressions exceed 100 million m 3 in volume and have developed in correspondence of large cave chambers where underground rivers are flowing.
