When cement is allowed to set why does it give off heat?
The hydration of cement is an exothermic reaction. Three exothermic reactions are important: - hydration of gypsum and tricalciumaluminate - hydration of dicalciumsilicate - hydration of tricalciumsilicate
Why 2 gypsum is added in the cement?
The construction industry uses both the natural and the synthetic forms of gypsum in Portland cement manufacturing. Although the amount of gypsum used in the mix represents a small percentage of the volume of all ingredients, gypsum has important functions.
What color is the gypsum rock?
the color for the gypsum rock is lik ewhite
How do muscles generate heat?

Does Uranus continues to generate internal heat through gravitational contraction?
False
How is gypsum converted to plaster of Paris?
All that needs to be done is to grind up the gypsum and heat it to 300 degrees F. Gypsum contains water, and the heating drives it off.

Does the moon generate heat for the earth?
the moon does not have its own energy to produce light that also produces heat therefore does not generate heat for earth and the sun generates heat for the earth.

How can you generate heat energy?
take a dump! :)
How is heat transferred from the sun to a solar heating panel?
Solar panels don't generate heat; they convert the energy of sunlight into electrical energy, which I suppose could be used to generate heat.
What is type c gypsum board?
Type C gypsum board meets and exeeds the fire resistance requirements of a type x board. It has mineral additives in the gypsum core that expands when exposed to heat. This expansion holds the board together longer during fire exposure. It is referred to by the Gypsum Association as "Improved Type X" board.
How much heat will the Tucker Clip Task Lighting generate, are they safe to use on books?
They do not generate enough heat to burn a book if cliped on and the bulb not close.
How nuclear fuels can be use to generate electricity?
Nuclear fissions in nuclear fuels generate heat and electricity.
What does wood generate?
wood generates heat and it has for many years. It can be burned to create heat.
