What is cement calcination?
Cement calcination is the process of heating limestone (calcium carbonate) to high temperatures, typically around 900-1000°C, to produce lime (calcium oxide) and carbon dioxide. This process is a crucial step in cement manufacturing, as it transforms raw materials into clinker, the primary component of cement. The release of CO2 during calcination contributes to greenhouse gas emissions, making it a significant factor in discussions about sustainable cement production. Overall, calcination is essential for creating the chemical compounds needed for strong and durable cement.
What heat cement?
The lime content that is found in cement causes cement to heat.
What are the disadvantages of polycarboxylate cement?
insoluble cement
What is high alumina cement used for?
High Alumina Cement is an inorganic material that form a dense texture when it reacts with water and has a excellent refractory, quick hardening property and resistance to chemical attacks. This type of cement is produced by grinding clinkers formed by calcining bauxite and lime

Who invented zinc phosphate dental cement?
Zinc phosphate dental cement was invented by William Morrison in 1873. He developed this cement as a restorative material that could be used in dental procedures.
What Sedimentary rock is used in cement?
Limestone is the most common sedimentary rock used in cement production. It is a key ingredient in the production of cement due to its high calcium carbonate content, which reacts with the other raw materials to form the clinker necessary for making cement.
What is used for making Cement?
cement is made up of calcium silicateand alminate
Why would a dentist choose a polycarboxylate cement instead of zinc phosphate to permanently cement a crown?
A dentist may choose a polycarboxylate cement over zinc phosphate for cementing a crown if the tooth is sensitive to temperature changes since polycarboxylate cement has better thermal insulation properties. Additionally, polycarboxylate cement releases fluoride, which can help prevent decay around the tooth.
How is sand used in cement making?

What materials where used in Making the first story Building in Nigeria?
cement
How is limestone used in making cement?
Limestone is used in making cement by being crushed and mixed with other materials like clay and sand. This mixture is heated in a kiln to create a powder called clinker, which is then ground into a fine powder and mixed with gypsum to make cement.
