He said, cement price increase as announced earlier will no longer be valid. He also said that manufacturers will have to get government approval before any price increase in the future. As for the cement manufacturers'' views, I could not find any in the mainstream media yet. Perhaps they may issue a statement in the near future for their side of the story as well. They were earlier saying ...
He said that cement companies were already earning very good profits as compared to their Indian and Chinese counterparts, therefore the recent increase cannot be justified under present ...
Cement Cement undergoes a chemical reaction when mixed with water, called hydration. This involves formation of a hard, interlocked, crystalline structure, which gives cement its high strength. The reason gypsum is added to cement is to increase its ''setting'' time, thus allowing for .

Monarch employees receive an 18centanhour pay increase, part of an agreement negotiated between the plant and Local 93 of the United Cement, Lime and Gypsum workers. The Company announces a million expansion, adding 50% more capacity to the plant—from 1,500,000 to 2,250,000 barrels of cement annually.
Called admixtures, these additives can be used to increase the workability of a cement mixture still in the nonset state, the strength of cement after application, and the material''s water tightness. Further, they can decrease the amount of water necessary to obtain workability and the amount of cement needed to create strong concrete. Accelerators, which reduce setting time, include calcium ...
An increase in the sizes of fine aggregate will create adequate free space among aggregates for cement hydration products generated from a larger amount of cement compared to the normal strength concrete. Due to the use of more cement, the heat of hydration and plastic shrinkage of fresh concrete will be increased but can be controlled with the utilization of mineral admixtures with clinker ...

How Much of Atmospheric CO2 Increase is Natural? August 27th, 2014 by Roy W. Spencer, Ph. D. NOTE: The following post has led to many good comments. The best argument advanced that I am wrong is from a ~1,000 year record of CO2 from the Law Dome ice core (a record I was unaware of) which suggests the recent CO2 increase is almost entirely anthropogenic in origin. I frequently get .
