Most professional and independent builders utilize cement whenever a project needs for a sturdy, long-lasting binding medium.
When combined with other forms of aggregate, such as sand and stone, cement serves as a binder to create the composite material known as concrete. The three components are weak when used alone, but when combined, stones fit together like pieces of a three-dimensional jigsaw puzzle, and sand and cement fill up the spaces.
Without cement, the stones and sand would simply sag and fall apart. However, it is the stone, not the cement, that provides concrete with its shear and compressive strengths.
Concrete can be fully blended with the components in a cement mixer to produce a consistent output. However, with a little caution and work, it is also possible to mix concrete by hand without a mixer.
Concrete mixtures are occasionally required to embed gates, fence, or clothes line posts into the earth. Making a concrete slab to serve as the foundation for something like a fuel bunker is another option.
Concrete may be made with just cement, stone, sand, and water. A shovel, a couple of buckets, and possibly a sheet of plastic are the only necessary pieces of equipment.
