Concrete is a composite building material made from the combination of aggregate and cement binder. The most common form of concrete is Portland cement concrete, which consists of mineral aggregate (generally gravel and sand), Portland cement and water. The two major components of concrete are a cement paste and inert materials.

Chemical Admixtures. Chemical admixtures are watersoluble chemicals that are added in relatively small amounts to concrete in order to change certain properties. Understanding how chemical admixtures work and designing new and improved admixtures is an important aspect of cement .

Portland cement''s chemistry comes to life in the presence of water. Cement and water form a paste that coats each particle of stone and sand—the aggregates. Through a chemical reaction called hydration, the cement paste hardens and gains strength. The quality of the paste determines the character of the concrete.

No. The Understanding Cement book gives the essentials of how cement is made and what happens when you use it in concrete or mortar. It is aimed at nonchemists and takes you painlessly to an intermediate level of cement materials science and chemistry probably about as far as most people in the industry need to go.

A material other than water, aggregates, or cement that is used as an ingredient of concrete or mortar to control setting and early hardening, workability, or to provide additional cementing properties. Admixtures are generally used to alter the properties of concrete (such as increased workability or reduced water content, acceleration or retardation of setting time,

Chemical Composition of Cement The raw materials used for the manufacture of cement consist mainly of lime, silica, alumina and iron oxide. These oxides interact with one another in the kiln at high temperature to form more complex compounds. The relative proportions of these oxide compositions are responsible ... in hard concrete.

Cement mixed with water causes a chemical reaction and forms a paste that sets and hardens to bind individual structures of building materials. Cement is an integral part of the urban infrastructure. It is used to make concrete as well as mortar, and to secure the infrastructure by binding the building blocks.

Writing a book on the chemistry of cement and concrete is a very responsible task, and if we take into account very valuable works of Lea and principally of Taylor, even unusually responsible. His last book is of the highest value and, apart from its clear presentation of all important problems of cement chemistry.
