Is cement a compound or a element?

Answer 1

hydrogen, sodium, potassium, lithium, rubidium, cesium, barium, beryllium, strontium, magnesium, boron, gallium, indium, thallium, carbon, germanium, tin, lead, nitrogen, phosphorus, arsenic, antimony, bismuth, oxygen, sulfur, selenium, tellurium, fluorine, chlorine, bromine, iodine, helium, neon, argon, krypton, xenon, yttrium, titanium, zirconium, vanadium, niobium, chromium, molybdenum, tungsten, manganese, cobalt, nickel, copper, silver, zinc, cadmium Mercury, and the lanthanides.

Answer 2

The chemical elements present in a common cement such as Portland cement can include:

1. CaO calcium oxide, aka quicklime
2. SiO2 silicon dioxide, aka silica
3. Al2O3 aluminum oxide, aka alumina
4. Fe2O3 iron III oxide, aka ferric oxide
5. MgO magnesium oxide, aka magnesia
6. Alkalis (soluble bases such as sodium oxide and potassium oxide)
7. SO3 sulfur trioxide, aka sulfate

Answer 3

Cement is a compound made of various substances such as limestone, clay, and gypsum. It is not an element.

Answer 4

An element seems too basic for cement. Cement is a mixture or a compound.

Answer 5

No.

Elements cannot be broken down into simpler substances. Concrete is made up of many different substances.

Answer 6

No. it is man-made and it has so many different elements it is kinda nuts. It's kinda like a hot dog!

Answer 7

Elements are the simplest unit the maintains properties. Cement is a combination of different elements that are bonded together, therefore it is a compound.

Answer 8

The different elements in cement are calcium, Magnesium , silicon, oxygen and Carbon. They are present in compounds such as MgO, SiO2 CaCo3 etc..

Answer 9

No, Concrete is a homogeneous mixture.
