Concrete is a composite material which is composed of water, aggregate, and cement. Additives and reinforcements are used to achieve the physical properties of the finished material. Fluid mass is formed when we mix all the above mentioned ingredients and that is easily molded into different shapes. Over time, hard matrix is formed by the cement which binds the rest of the ingredients together into a durable stone-like material. Concrete production involves Mixing concrete, Workability and Curing.
A journal is a periodical publication intended to further progress of science, usually by reporting new research.

Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity.
