What are the chemical properties of cement?
Portland Cement is made by baking limestone to remove the carbonate, and to this is added some gypsum (to provide sulphate) and diatomaceous earth (effectively a very finely divided silica). When curing, many complex chemicals are formed, the crystals of which give cement its strength. Silicates, sulphates, and carbonates.
Why folding motion is used for gic?
The folding motion in Glass Ionomer Cement (GIC) application is used to remove excess material and to ensure proper adaptation of the cement to the tooth surface. This motion helps create a homogenous mix and reduces air entrapment, improving the mechanical properties and bond strength of the cement.
How could heat transfer from cement to your feet?
Heat transfer from the cement to your feet can occur through conduction. When you walk on the cement, heat from the cement is transferred to your feet by direct contact. Cement is a good conductor of heat, so the transfer occurs quickly.
Can radiation penetrate cement?
Yes, radiation can penetrate cement to some extent depending on the type of radiation and the thickness of the cement. Generally, thicker and denser materials like lead are more effective at blocking radiation than cement.

What are the insoluble residue in cement?
The insoluble residue in cement mainly consists of unhydrated cement particles, minerals, and impurities. These residues can affect the performance and properties of the cement, such as strength development and durability. Proper quality control measures are important to ensure optimal composition and properties of cement.
What properties does limestone have that makes it good building material?

What is the guide words for cement?
The guide words for cement typically include "Portland cement," which is the most common type used in construction, as well as terms like "hydraulic cement," referring to cements that set and harden when mixed with water. Other guide words may include "blended cement," which combines different materials for specific properties, and "cementitious," relating to materials that have cement-like properties. These guide words help in identifying the various types of cement and their applications.

What is a cement rock?
Cement rock, also known as raw material for cement, primarily consists of limestone, clay, and other minerals. It is mined and processed to produce clinker, which is then ground to create cement. The composition and quality of cement rock are crucial for the efficiency and properties of the final cement product. It serves as the foundational material in construction and infrastructure development.

Why glass ionomer cement not mixed on glass slab?
Glass ionomer cement should not be mixed on a glass slab because the ions present in the cement can react with the glass slab, leading to contamination and affecting the setting reaction of the cement. This can compromise the physical properties and performance of the cement. It is recommended to use a disposable mixing pad or a mixing paper to prevent any unwanted reactions and ensure the proper setting of the glass ionomer cement.
What are the chemical compositions of antibacterial cement?
Antibacterial cement typically contains additives such as triclosan or silver ions that have antibacterial properties. These additives are incorporated into the cement mix to prevent bacterial growth and promote a sterile environment in medical or hygiene-sensitive applications.
