Cement needs calcium. It is the calcium in cement that gives its properties to help form concrete.
This is why limestone is the main raw material for cement.
Limestone is made from calcium-rich shells and skeletons of prehistoric sea creatures.
The blog 2 Major Roles of Limestone in Cement Manufacturing written on the mining company's website Ftmmachinery describes the ingredients of cement and what raw materials these ingredients come from.

∙ 12y agoYes,Sorel in 1867 announced the discovery of an excellent cement formed from the combination of magnesium oxide and magnesium chloride solution. This cement type is known by many different names, such as Sorel, magnesite and magnesium oxychloride cement. This cement has many superior properties to Portland cement. However, there are two other known magnesia cements. The first is magnesium oxysulfate (MOS), which is the sulfate analogue of magnesium oxychloride and is formed by the combination of magnesium oxide and magnesium sulfate solution. The second is magnesium phosphate cement (MAP), formed by the reaction between magnesium oxide and a soluble phosphate, such as ammonium phosphate monobasic (NH4H2PO4)

Cement is calcium what?
their is calcium in cement because it mixes well and can stick wel
What chemical is used to strengthen white cement?
The chemical commonly used to strengthen white cement is calcium chloride. It is added in small amounts to the cement mixture during production to improve its strength and durability. Calcium chloride also helps to accelerate the setting time of the cement.
What kinds of things are made from calcite?
Bones, rocks, kidney stones, antacids, cement, pearls..........

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.
What are two products made from calcium compounds?
Chalk, cement
What is the substance that is heated with calcium carbonate to make cement?
carbondioxide
Which metallic oxide is major constituent of cement?
Hydrated cement produces CaO. So calcium oxide is a major constituent. Silicon dioxide is also produced resulting in calcium silicate.
