cement is a compound because you cannot see all the parts. :)
First of all to correct your spelling. It is 'Concrete', not 'concrerte'. As concrete it is an heterogeneous mixture of cement, sand, gravel and water.
No, cement is not a covalent compound. Cement is a mixture of various compounds, primarily calcium silicates and aluminates, which react with water to form a solid matrix. These compounds are held together by ionic bonds, not covalent bonds.
Mixture
I consider cement as a heterogeneous mixture.
Mortar is heterogeneous. You can clearly tell the different parts of the mixture apart from one another (calcium carbonate and sand), thus, it is a heterogeneous mixture. The two particles are not chemically combined, but simply mixed together. Heterogeneous Mixture.
It is a mixture
yesFalse. It is a mixture.
Concrete is a mixture containing cement, sand, gravel and water.
Concrete is a composite construction material, composed of cement (commonly Portland cement) and other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate made of gravel or crushed rocks such as limestone, or granite, plus a fine aggregate such as sand), water and chemical admixtures.

Mixture
Concrete is not a compound after water evaporates and it hardens. Concrete is a mixture of aggregate materials (such as sand and gravel) and cement, which binds the materials together. When water is added to the mixture, a chemical reaction occurs with the cement that causes it to harden and bind the aggregate materials together.
Cement is a mixture, not a compound. It primarily consists of various materials, including limestone, clay, and gypsum, which are combined and then heated to form clinker. This clinker is then ground into a fine powder, resulting in the final product known as cement. The diverse components retain their individual properties, making the overall product a mixture rather than a single chemical compound.
Yes, concrete is a mixture of several materials, including cement, aggregates (such as sand and gravel), and water. Cement is a covalent compound, specifically calcium silicates that form through a chemical reaction. Therefore, while concrete as a whole is not a single covalent compound, one of its main components, cement, is.
