dehydration of the starting natural gypsum during the grinding process may indeed severely influence the cements particle size distribution thus providing very different values of specific surfaces and sieve residuals while maintaining an identical grinding time i.e. energy which is introduced to the grinding

Gypsum is added to control the 8220setting of cement8221. If not added the cement will set immediately after mixing of water leaving no time for concrete placing.

H. CHU.
what is the role of gypsum. if we are add2.50 gypsum for grinding cement and same clinker we add 4.0 gypsum for grinding cement. what is the effect in compressive strength.
We are adding the gypsum not only for control the setting of cement. It is contribute for cement early strength by SO3.
manufacturing of cementtype of cement percentage gypsum in cement
adding of gypsum to concrete decrease the compressive strength of concrete or not
Gypsum also influences the grindability of the cement that is the grinding energy required to produce cement.
Gypsum is a mineral and is hydrated calcium sulphate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement so its is generally termed asretarding agent of cement. It is mainly used for regulating the setting time of cement and is an indispensable component.
From the limestone quarry to the delivery of the end product follow every step in the cement manufacturing process.
nbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbsp Other raw materials are used to control the kiln feed mix design namely sand and iron ore. The sand and iron ore are transport from outside the plant from different suppliers by trucks and unloaded into open yard piles called sand and iron ore piles. nbsp nbsp
The limestone is crushed in the first crusher called a jaw crusher and then fed into the second crusher called an impact crusher with mixing of clays to reduce particle size below 50mm. The discharged raw mix limestone 70 clays 30 is fed onto a belt conveyor and passed across a bulk material analyzer. The raw mix is fed into a circular storage unit called a raw mix storage. Then the mix is extracted transversely from the stockpile by reclaimers and conveyed to a raw mill bin called the raw mix bin for grinding.
The other raw materials that are used in cement manufacturing called additives are high purity limestone sand and iron ore. The high purity limestone is crushed in a lone in jaw crusher and then crushed more in a secondary crusher to reduce the size to completely pass through a 50mm sieve. Then it is stacked by a limestone stacker into a longitudinal storage unit called the limestone storage stockpile. Finally the limestone is extracted transversely from the stockpile by reclaimer and conveyed to a raw mill bin called the limestone bin for grinding. nbsp nbsp
