Composition of cement - Penn State College of Engineering

2000-3-17 · It is largely responsible for portland cement’s initial set and early strength gain. Dicalcium silicate, C 2 S: C 2 S hydrates and hardens slowly. It is largely responsible for strength gain after one week. Ferrite, C 4 AF: This is a fluxing agent which reduces the melting temperature of the raw materials in the kiln (from 3,000 o F to 2,600 ...

Chemical Composition of Cement

2014-1-30 · 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 for influencing the various properties of cement; in addition to rate of cooling and fineness of grinding. Table 1.4

2018-4-4 · Cheap quarried raw materials usually contain Cr, Mn, and Fe. For example, lime stones and clays usually contain 0.3–1% and 5–15% Fe 2 O 3. Keeping Fe 2 O 3 below 0.5% is desirable to make WC, and as such, kaolin and sand are used instead of other clays in making WC.

What is Concrete? Composition & Types of Concrete - Civil ...

2021-9-4 · Concrete, an artificial stone-like mass, is the composite material that is created by mixing binding material (cement or lime) along with the aggregate (sand, gravel, stone, brick chips, etc.), water, admixtures, etc in specific proportions. The strength and quality are dependent on the mixing proportions.

8 Main Cement Ingredients & Their Functions - Civil ...

2021-9-4 · The main features of these cement ingredients along with their functions and usefulness or harmfulness are given below: Lime: Lime is calcium oxide or calcium hydroxide. The presence of lime in a sufficient quantity is required to form silicates and aluminates of calcium. Deficiency in lime reduces the strength of property to the cement.

Clinker quality depends on raw material composition.

2014-1-14 · Portland cement is the most common type of cement in the world. It is used primarily to make concrete, mortar, and grout. Portland cement manufacturing begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement

Lime Kiln Dust as a Potential Raw Material in Portland

2004-9-28 · The raw materials are heated to a sintering temperature of between 1,400º C and 1,500º C causing a series of chemical reactions that forms portland cement clinker (Johnson, 1985; Portland Cement Association, undated). The design of the raw material mix takes into account only the chemical oxide composition of the ingredients and basically ignores

Pozzolanic Material - an overview | ScienceDirect Topics

Michael John McCarthy, Thomas Daniel Dyer, in Lea's Chemistry of Cement and Concrete (Fifth Edition), 2019. C 3 A. Pozzolanic materials do not change the types of hydrates that form from the hydration of C 3 A. However, if the mixes contain calcium hydroxide, C-S-H forms as a consequence of the pozzolanic reaction. In the presence of calcium sulfate and pozzolanic material, C 3 A hydration ...
