CementHistory of cement Britannica

 · CementCementHistory of cement The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of more than 2 000 years ago and of subsequent construction work in western Europe.

Magnesium OverdoseSymptoms Causes Treatments

 · Magnesium overdose is an excess of magnesium in the body. Magnesium is an essential mineral that helps muscles function and maintain energy. In the absence of kidney disease your body naturally removes excess magnesium.A magnesium overdose also called magnesium toxicity or hypermagnesemia generally occurs when magnesium is ingested in large quantities in the form of a

These are further separated into five groups that differ with respect to their net charge (Table 2). 1 1 Clay Minerals

Existing and New Processes for Beneficiation of Indian

 · The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast the focus is on the beneficiation of low-grade resources. However most of these ores do not respond well to the conventional beneficiation techniques used to achieve a suitable
