Is concrete a compound an element or a mixture?
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.
Is concrete a compound after the water evaporates and it hardens?
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.
Is a compound irreversible?
That depends on what is being mixed together. Two examples of this are: If you mix sand, gravel, and water it is reversible and you can separate the mixture back to its original three parts. If you mix sand, gravel, water, and cement powder it is not reversible as the water will react with the cement powder creating liquid cement and the sand and gravel will form concrete with the liquid cement. After a few hours the liquid cement in the concrete will set and the concrete mixture will become as hard as rock. It is now no longer possible to separate the mixture back to its original four parts.
Common salt dissolves in water easily .give reason?
Sodium chloride is a polar compound as water.
Why is concrete a mixture?
Concrete is a mixture because it is composed of different materials, such as cement, water, aggregates (like sand and gravel), and sometimes additives. These components are combined in specific proportions to create a strong and durable building material with desired properties like strength, durability, and workability. Mixing these materials together allows for a uniform distribution, ensuring consistent quality in the final product.
Are portland cement rocks sand and water a compound?
Yes, Portland cement rocks, sand, and water are indeed a compound.
Is cement a compound?
yesFalse. It is a mixture.
Is cement a compound or a mixture?
Cement is a mixture, not a compound. It is made up of various materials such as limestone, clay, and gypsum that are combined together through a complex process to form the final product used in construction.
Is cement an organic compound?
Cement itself in inorganic. However some additives and hardeners mixed with cement are polymers, which are organic.
Is cement a compound mixture or element?
It is a mixture
Is cement a covalent compound?
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.
Is concrete a covalent 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.
Why do bivalves produce a cement compound?
Bivalves produce a cement compound to attach themselves to substrates in their environment, such as rocks or other surfaces. This helps them stay in place and prevent being dislodged by water currents or predators. The cement compound is also used to seal their shells shut for protection.

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.
