Also known as: admixtures

Also known as: paving

Pour is to cast concrete.

Also known as: cast

slump test

stained concrete
Stained concrete is colored concrete and is can be used in driveways and other areas. Stained concrete is available in vibrant colors and can also be chosen to complement the style and color of your home.

Also known as: stained concrete patterns

stamped concrete
Stamped concrete is often used in place of concrete pavers as it can look like brick, tile or blocks and can be stamped with a pattern. A foundation of concrete is poured and then stamping the pattern while it is still damp.

Also known as: stamped concrete patterns

Stenciled concrete is used to mimic other paving materials like brick or tile by using stencils.

Also known as: stenciled concrete patterns

Workability is how easily fresh concrete can be used and molded and put into forms.
