A composite material: concrete - RSC Education

A composite material: concrete In this activity students make concrete with various additives then investigate how changing the additives can change the properties of the resulting composite. Concrete is a mix of cement, water, sand and gravel. In the first lesson students prepare samples of concrete and leave them to set.

Composite Materials - Concrete

Concrete is regarded as a composite material because it is composed of a number of materials that combine to form this versatile building material. Most concrete is made up of Portland Cement, aggregates (gravel, crushed stones) and sand. Water is added to the mix. Concrete can be purchased as precast products, such as paving stones.

10 Surprising Examples of Composite Materials – SMI Composites

4. Translucent Concrete. Concrete is a primitive example of composite material because of the combination of small rocks and cement that it holds. When optic fibers, similar to those found in fiberglass, are added to concrete, you get translucent concrete. The look and feel of the concrete can vary depending on the ratio of cement to optic ...

Concrete - CCSF

Concrete Concrete is an example of a large particulate reinforced composite material. It is an important structural material that, by tonnage, is used more than steel in the U.S. Concrete is basically a ceramic aggregate composite material that is composed of fine and coarse aggregates (60–80%) embedded in a hard matrix of a cement paste and water, sometimes with entrained air.
