What is cement made of?
Cement is made up of,Calcareous materials (Limestone)Argillaceous materials (clay)GypsumPozzolanic materials (flyash, pumicite.etc.,)Generally cement is made up of,Argillaceous material (clay)Calcareous material (limestone)GypsumPozzolanic materialsCement is a mixture of elements such as clay, limestone, sand and it's a powdery, fine and soft substance. It is mixed with water and become a solid mass called concrete.Cement is made mostly of a mixture of elements that are found in natural materials such as limestone, clay, sand and/or shale. The cement used in most concrete is called "Portland cement" and consists of finely powdered rock made from limestone, which includes calcium silicates, calcium oxide, and calcium sulfate.Limestone, Clay, Sand, Stone or other Aggregates.calcareous rocks(limestone)argillaceous rocks(clay)coal dustgypsumpozzolanic materialsiron oremagnesiumalkaliesRaw MaterialsIt's important to have the correct proportions of calcium, silicon, aluminum, and iron. To achieve this mix the overall chemical composition and structure of the individual raw ingredients can vary. The most common two materials are limestone and clay with other industrial byproducts added (These may not be strictly "raw" materials). All the materials are crushed to a fine powder, put in a mixer, then into a kiln to make cement power.The raw materials required for cement are, Calcareous materials (limestone) Argillaceous materials (clay) Gypsum Pozzolanic materials like fly ash, volcanic ash, pumicite.the main ones are limestone and shale. Gypsum is also used to make the cement set more slowly.Cement is mainly made from limestone (ordinary portland cement (OPC)) with other additive such as gypsum. It can also be made from blast furnace slag or fly ash from power stations with the addition of some limestone.
What would you call the calcium carbonate deposits?
It depends on the context - in geology they maybe called limestone deposits. In a corrosion sitaution they may be called calcareous deposits
What materials change by heat?
Many materials such as plastic melt and some materials burn such as wood

How might a lowering of the pH of seawater affect the abundance of calcareous sediment on the seafloor?
Lowering the pH to less alkaline and more acidic levels would cause more calcareous materials to dissolve in seawater thereby reducing the abundance of calcareous sediment on the seafloor.

What is a calcareous sponge?
A calcareous sponge is any of a variety of sponge of the class Calcarea, with skeletons composed of spicules of calcium carbonate.
How is Portland cement made?
Grinding the raw materials (Calcareous materials and argillaceous materials)Mixing in correct proportionsBurning them in kiln at a temperature of 1300 - 15000CAt this temperature the material sinters and partially fuses to form clinkers.Clinkers are cooled and ground to a fine powder with addition of about 2-3% of gypsum.And it is weighed and packed.
