ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates.

Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.

The Colosseum in Rome was built largely of concrete, and the concrete dome of the Pantheon is the world's largest unreinforced concrete dome.

Today, large concrete structures (for example, dams and multi-storey car parks) are usually made with reinforced concrete.

These standards help to identify the various properties of concrete including strength, elasticity, hardness, and workability.

In addition to its standard concrete mixes, KWCM also provides various types of specialized concrete, including early strength concrete, self-consolidating concrete, environmental-friendly slag concrete and light-weight concrete for building and infrastructure projects.

Often, additives (such as pozzolans or superplasticizers) are included in the mixture to improve the physical properties of the wet mix or the finished material.

Most concrete is poured with reinforcing materials (such as rebar) embedded to provide tensile strength, yielding reinforced concrete.

When aggregate is mixed together with dry Portland cement and water, the mixture forms a fluid slurry that is easily poured and molded into shape.

The cement reacts chemically with the water and other ingredients to form a hard matrix that binds the materials together into a durable stone-like material that has many uses.

After the Roman Empire collapsed, use of concrete became rare until the technology was redeveloped in the mid-18th century.
