Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement cement paste that hardens cures over time. In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form
Composition of cement. Introduction Portland cement gets its strength from chemical reactions between the cement and water. The process is known as is a complex process that is best understood by first understanding the chemical composition of cement.
Concrete is the most widely abundant engineering material in the world today in terms of volume is not officially a ceramic but is rather a composite made up of sand, aggregate, and cement. With the addition of water the cement reacts to form a ceramic like structure around the sand and aggregate particles. The strength of the concrete is gained from a reaction between the water
In the 2,000 years since the Roman Empire employed a naturally occurring form of cement to build a vast system of concrete aqueducts, researchers have analyzed the molecular structure of natural
The major cements composition and properties Portland cement Chemical composition. Portland cement is made up of four main compounds tricalcium silicate 3CaO SiO 2, dicalcium silicate 2CaO SiO 2, tricalcium aluminate 3CaO Al 2 O 3, and a tetracalcium aluminoferrite 4CaO Al 2 O 3 Fe 2 O 3.
When a concrete structure is prone to chemical actions its durability gets affected. The chemicals may cause cracking of concrete, volume change and deterioration of structure. The life of structure reduces and it can lead to failure of structures. Different types of chemical attacks and their effects on concrete structures are explained below.

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 only behind water as the planets mostconsumed resource.
Concrete provides good performance through the service life of the structure when concrete is mixed properly and care is taken in curing it. Good concrete can have an infinite life span under the right conditions. This paste binds the aggregate particles through the chemical process of hydration. In the hydration of cement, chemical changes
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 worksite which reduces costs. Concrete is a noncombustible material which makes it firesafe and able withstand high temperatures.
Structure and physical properties of Hardened portland Cement Paste by T. C, POWERS Research md Development Oivision, Portland Cement Association, Chicago, Illinois Methods of studying the submicroscopic structure of Portland cement paste are described, and deductions about structure are presented. The main component, cement gel, is deposited in
Some very basic chemistry will help a lot with understanding how cement is made and how it works. If you missed out on chemistry at school, or it just seems a long time ago, the following short notes might be useful. Chemical symbols are abbreviated forms of the names of chemical elements, eg Ca calcium Si silicon K potassium.
naturally occurring form of cement to build a vast system of concrete aqueducts and other large edifices, researchers have analyzed the molecular structure of natural materials and created entirely new building materials such as steel, which has a welldocumented crystalline structure at the atomic scale.
Hydration products. The products of the reaction between cement and water are termed 34hydration products.34 In concrete or mortar or other cementitious materials there are typically four main types Calcium silicate hydrate this is the main reaction product and is the main source of concrete strength. It is often abbreviated, using cement chemists39 notation, to 34CSH,34 the dashes indicating
