Which cement is known for its ability to stimulate the formation of secondary dentin?
Calcium Hydroxide
Which material is used for filling tooth cavity?
Dentists mix a liquid called 0.1m NaOH (Sodium Hydroxide) with particles of Cement.
Why is calcium hydroxide used in food?
It's used "for processing water (for alcoholic and soft drinks)" -http://en.wikipedia.org/wiki/Calcium_hydroxide
What is the Difference between lime and cement?
Lime is calcium oxide (CaO, or hydroxide Ca(OH)2); cement is a more complex compound, generally a calcium aluminosilicate.Cement is a combination of silica-alumina minerals while lime lacks this property.It does not have any particular mineral in itMinerals present in cement actually enhances the binding power of mortar so as in case of cement we have more chances of strong binding.Lime increases its volume by 2 to 3 units so it cant be used in the process of construction as it can cause eruption.Lime absorbs carbon-dioxide and ultimately forms calcium carbonate(a protective sheath)As a result, lime mortar is considered by environmentalists to be "carbon neutral." In contrast, cement production contributes greatly to global warming, as copious amounts of carbon dioxide are released during its production.
What is purpose of tricalcium silicate in cement?
Tricalcium silicate is the main mineral responsible for strength development in the hydration of portland cement. Portland cement contains 50 to 70 percent C3S (Tricalcium aluminate) It is also known as alite. To keep it simple, C3S reacts with water to form calcium silicate hydrate (CSH) and a byproduct, calicum hydroxide. CSH is what gives concrete its strength and binds the aggregates together.
What is Chemical name of cement?
The very basic chemical compound of cement is Calcium Hydroxide. The calcium hydroxide is mixed with water and the carbon dioxide in the air acts on it to harden it.
Which cement is known for its ability to stimulate the formation of secondary dentin?
Calcium Hydroxide
What is the chemical containing hydroxide ions?
There are many. Water itself contains some free hydroxide ions. More common ones include Sodium Hydroxide solution, Potassium Hydroxide Solution, Slaked Lime Slurry, Concrete, Cement etc
Important materials made from limestone out of cement and diesel oil and glass and polyethene and sodium hydroxide and sulfuric acid?
Cement and Glass are the 2 most important materials made from Limestone.
You want 4 bases and their uses?
1) Sodium hydroxide: used to make soap and paper 2) Calcium hydroxide: used to make cement and plaster 3) Ammonia: House cleaning product and fertilizer 4) Magnesium hydroxide and aluminum hydroxide are used in antacids to treat heartburn
Why is lime used compare to other substances?
Limestone is widely used to prepare cement, calcium hydroxide or as building material.

What is made out of plaster?
There are a couple types of plaster that can be used for interior walls. One form of plaster is lime plaster; it is made up of calcium hydroxide and sand. Cement plastic is a mixture of sand, water, portland cement, and suitable plaster.
What is the chemical reaction occur in cement?
Cement is the mixture of tricalcium silicate, dicalcium silicate, tricalcium aluminate, tetracalcium aluminoferrite and gypsum. Cement is mixed with water, the silicates and aluminates in the cement undergo a chemical reaction, the resulting hardened mass is formed.2 Ca3SiO5 + 7 H2O ---> 3 CaO.2SiO2.4H2O + 3 Ca(OH)2 + 173.6kJTricalcium silicate + Water--->Calcium silicate hydrate+Calcium hydroxide + heat2 Ca2SiO4 + 5 H2O---> 3 CaO.2SiO2.4H2O + Ca(OH)2 + 58.6 kJDicalcium silicate + Water--->Calcium silicate hydrate + Calcium hydroxide +heat
What is the origin of cement and where it was first used in primitive form?
The first cements existed at least as far back as the civilizations of Greece and Minoan, some 500 BC or so. These were composed of local Pozzolan materials, calcined and mixed with Calcium Hydroxide (burnt lime) to make a cement.
What are five examples of a base?
Answers: Potassium hydroxide, Barium hydroxide, Caesium hydroxide, Sodium hydroxide, Strontium hydroxide, Calcium hydroxide, Lithium hydroxide, Rubidium hydroxide...
