At the cement mills the clinker is mixed with other additives required for producing the specific type of cement. Gypsum for OPC, limestone for limestone cement, and slag for slag cement. The ball mill then grinds the feed to a fine powder. The fine powder is then sent to a separator whi...
In the past,we've shown in a tutorialhow GPS can be received and decoded with GNSS-SDRLIB and RTKLIB on Windows. The new Gypsum software should work on Linux and MacOS too. What's more, Phillip has written anincredible 4-part writeup on how Gypsum was implementedfrom scratch...

The Mohs Scale is used to determine the hardness of solids, especially minerals. It is named after the German mineralogist Friedrich Mohs. Here's the scale, from softest to hardest: Talc - easily scratched by the fingernail Gypsum - just scratched by the fingernail Calcite - scratches and is...
With non-hydraulic cement becoming more obsolete over the years, a new type of cement has taken the front seat which is called hydraulic cement. As of today, it is the most commonly used variation and is made using limestone, gypsum, and clay which are combined at a very high temperature...
A new explanation of how gypsum forms may change the way we process this important building material, as well as allow us to interpret past water availability on other planets such as Mars. The work is reported in Nature Communications.
The white sands on the Gulf of Mexico are made of smooth particles of limestone known as oolite, derived from the Greek word meaning egg stone. The white sands of White Sands, New Mexico, are made of gypsum crystals. Ordinarily, gypsum is dissolved by rain water, but the area around ...
