| Summary: | Concrete is a widely used construction material around the world, and its properties have
been undergoing changes through technological advancement. Numerous types of
concrete have been developed to enhance the different properties of concrete. So far, this
development can be divided into four stages. The earliest is the traditional normal
strength concrete which is composed of only four constituent materials, which are cement,
water, fine and coarse aggregates. With a fast population growth and a higher demand for
housing and infrastructure, accompanied by recent developments in civil engineering,
such as high-rise buildings and long-span bridges, higher compressive strength concrete
was needed. At the beginning, reducing the water-cement ratio was the easiest way to
achieve the high compressive strength. Thereafter, the fifth ingredient, a water reducing
agent or super plasticizer, was indispensable. However, sometimes the compressive
strength was not as important as some other properties, such as low permeability,
durability and workability. Thus, high performance concrete was proposed and widely
studied at the end of the last century. Currently, high-performance concrete is used in
massive volumes due to its technical and economic advantages. Such materials are
characterized by improved mechanical and durability properties resulting from the use of
chemical and mineral admixtures as well as specialized production processes. This paper
reviews the incorporation of mineral admixtures in binary, ternary and quaternary blended
mortars in concrete. |
