Yes. The cement used to make concrete usually has sand, aggregate and Portland cement in it. That would make it heterogeneous.
Homogeneous. The parts from which cement is made from are indiscernible.
No, a cement sidewalk is not a homogeneous mixture because it is made up of different components like cement, sand, gravel, and water that are not uniformly distributed throughout the material. It is more accurately described as a heterogeneous mixture.
Yes, a concrete sidewalk is considered homogeneous because it is composed of the same material throughout its structure, providing consistent properties and appearance across its surface.
Cement is a heterogeneous mixture because it is composed of different components, such as limestone, clay, and other materials, that are not uniformly distributed throughout the mixture.

Cement is a homogenous mixture, but concrete is not.

Cement is a heterogeneous mixture because it is composed of different components, such as limestone, clay, and other materials, that are not uniformly distributed throughout the mixture.
Concrete is a heterogeneous mixture composed of cement, sand, gravel, and water. It is not an element or a compound.
Within the concrete, there is cement, aggregate, and water. Cement is simply a glue that holds the rock or other aggregate together. Water activates the cement. Even cement itself isn’t a homogenous mixture, which means concrete could never be homogenous.

Concrete is considered a heterogeneous mixture because it is composed of various components such as aggregates (like gravel and sand) and cement that are visibly distinguishable.
