The question is possibly misstated. A substance can be either a compound OR a mixture.
A compound is a pure chemical substance consisting of more than one element that can be separated into simpler substances by chemical reaction. The elements are present in a fixed proportion, for example 1 atom of carbon can combine with 2 atoms of oxygen to form carbon dioxide. Compounds have definte properties such as melting points, solid densities, etc. the elements making up the compound do not retain their original properties.
By contrast, a mixture can be separated physically into different components with different properties (while compounds must be separated by chemical means). Conversely, mixtures can be created by mechanical means alone, but a compound can only be created (either from elements or from other compounds, or a combination of the two) by a chemical reaction. A mixture will have multiple properties depending on what part of the mixture you examine - different parts might have different colors, densities, melting points, etc.
Concrete is a composite mixture of cement, sand and (usually) coarse aggregate like gravel or crushed rock. Water is mixed with it and reacts with the cement to form a very hard hydrate. In reality, "wet" concrete is concrete where not all the water has reacted yet. Very little of the water actually evaporates by the time the concrete becomes "dry". The cement in the concrete is a compound. The concrete as a whole is a mixture.
concrete is mixture!

Is concrerte an element compound homogeneous heterogeneous?
Concrete is a heterogeneous mixture composed of cement, sand, gravel, and water. It is not an element or a compound.
Is a concrete a compound element or mixture?
Mixture
Is concrete a element or compound?
Concrete is a mixture.Concrete is composed of cement and other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate made of gravels or crushed rocks such as limestone, or granite, plus a fine aggregate such as sand), water, and chemical admixtures
Is concrete a pure substance or mixture?
Concrete is a mixture, not a pure substance. It is made up of various substances such as cement, water, aggregates (sand, gravel), and additives. Each of these components retains its own properties and can be physically separated from the others.

Mixture
What is the chemical formuls of concret?
Concrete is a mixture not a chemical compound.
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 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 or a mixture?
Concrete is a mixture, not a compound. It is composed of different materials such as cement, water, and aggregates (like sand and gravel) that are combined together to create a solid structure. Each ingredient retains its individual properties within the mixture.
