- Cellular Contains air or gas bubbles suspended in mortar and either no coarse aggregates or very limited quantities are included in the mixture. Use where high insulating properties are required.
- Shot-crete or Gunite The method of placement characterizes this type of concrete, which is applied via pneumatic equipment. Typical uses are swimming pools, shells, or domes, where formwork would be complicated because of the shape of the structure.
- Ferrocement Basically a mortar mixture with large amounts of light-gauge wire reinforcing. Typical uses include bins, boat hulls, and other thin, complex shapes.

*ANGLES HAVE BEEN USED* in construction almost as long as structural steel
has been around, and were commonly used as components of built-up shapes.
