It is strong, inexpensive to produce and versatile.
Concrete is however a brittle material that lacks ductility.
This means that it fails suddenly without warning. Concrete is a material based which is constantly being improved upon. Several chemical admixtures and additives can be added to concrete to improve its properties. The properties of interest in a structural material are strength, toughness and ductility. Strength is defined as the maximum load a material can withstand.
