Hydration of Portland Cement. Introduction Portland cement is a hydraulic cement, hence it derives its strength from chemical reactions between the cement and water. The process is known as hydration. Cement consists of the following major compounds (see composition of cement): Tricalcium silicate, C 3 S; Dicalcium silicate, C 2 S; Tricalcium ...
Cement - Wikipedia
A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is …
Chemical Reactions in Pozzolanic Concrete
A direct cement replacement is a type of cement substitute that can replace the Portland cement without requiring a pozzolanic activity/reaction discussed below [1]. The most common type of these replacements is Ground Granulated Blastfurnace Slag (GGBS), which is a by-product of the iron and steel industry, is a fine white powder.

Cement In the most general sense of the word, a cement is a binder, a substance that sets and hardens independently, and can bind other materials together. Cement used in construction is characterized as hydraulic or non-hydraulic. Hydraulic cements (e.g., Portland cement) harden because of hydration, chemical reactions

Cement Chemistry. Cement is chiefly of two kinds based on the way it is set and hardened: hydraulic cement, which hardens due to the addition of water, and non-hydraulic cement, which is hardened by carbonation with the carbon present in the air, so it cannot be used underwater.
Chemical Composition of Cement - University of Babylon
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

Concrete: Scientific Principles
Concrete is not as likely to rot, corrode, or decay as other building materials. Concrete has the ability to be molded or cast into almost any desired shape. Building of the molds and casting can occur on the work-site which reduces costs. Concrete is a non-combustible material which makes it fire-safe and able withstand high temperatures.

How Concrete is Made - Portland Cement Association
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.
