Dec 30, 2018  After his extensive research, Bogue has devised a calculation system that assumes four main minerals in cement clinker responsible for cementitious properties..

Cement and concrete materials science is a multidisciplinary subject, involving engineers, geologists, chemists, physicists and many others. This website is for the

described as the materials science of concrete. Among Bogue’s personal contributions was a landmark paper, Calculation of Compounds in Portland Cement [1], published in 1929. To understand the significance of the paper, it is necessary to know a little about portland cement and its manufacture. Portland cement was invented in 1824. Its essential

Jul 01, 2010  1st July 2010. 14th March 2016. Bogue Calculation explained. The standard Bogue calculation refers to cement clinker, rather than cement, although it can be adjusted for use with cement. This is a very commonly-used calculation in the cement industry. The calculation assumes that the four main clinker minerals are pure minerals with compositions:

Jan 31, 2018  The Bogue calculation is a means of allocating the four main oxides in Portland cement clinker to the four main phases present after firing in a cement kiln. The calculation is based on the assumption that the phases are present as pure tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetra-calcium alumino-ferrite and that the ...

Feb 06, 1989  The Bogue calculation gives low results for alite and inaccurate ones for the other phases in Portland cement clinkers, largely because the compositions of the phases differ markedly from those of the unsubstituted compounds which it assumes to be present.

The Bogue equations, as they eventually became known, were incorporated in the ASTM specification for portland cements in 1940, and have been used for the subsequent 70 years for process control, cement classification, and specification compliance. The accuracy of the Bogue calculations has been evaluated by comparison to direct

The Bogue calculation of cement mineral composition A simple estimate of the phase composition of a portland cement can be obtained from the oxide composition if one assumes that the four main cement minerals occur in their pure form. With this assumption, all of the Fe 2 O 3 is assigned to C 4 AF and the remaining Al 2 O 3 is assigned to C 3 A.

Bogue Equations • The standard Bogue calculation refers to cement clinker, rather than cement • The calculation assumes that the four main clinker minerals are pure minerals with compositions: • Alite: C 3 S, or tricalcium silicate • Belite: C 2 S, or dicalcium silicate • Aluminate phase: C 3 A, or tricalcium aluminate • Ferrite ...

Bogue calculation Calculation to give the approximate proportions of the four main clinker minerals in Portland cement, requiring the clinker bulk analysis and the free lime content, the

Composition of cement. Introduction Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration.This is a complex process that is best understood by first understanding the chemical composition of cement.

Dec 30, 2019  Concrete is a mix of cement, the Bogue calculation gives a useful approximation and is widely used within the cement industry. The amount of CO2 emitted by the cement industry is nearly kg of CO2 for every kg of cement produced pd is not very environmentally friendly.

The Bogue calculations are routinely used to estimate the quantities of the four major mineral phases in portland cements and clinkers for compliance with specifications, such as ASTM C 150.

Mar 18, 2013  Firstly, we need to recognise that industrial Portland cement clinker is not an equilibrium product with a mineral composition as given by the Bogue calculations. The rapid cooling of the clinker as it passes under the flame in the kiln and falls into the cooler results in non-equilibrium cooling with the liquid flux in the clinker being frozen ...

Feb 06, 1989  The Bogue calculation gives low results for alite and inaccurate ones for the other phases in Portland cement clinkers, largely because the compositions of the phases differ markedly from those of the unsubstituted compounds which it assumes to be present.

Aug 19, 2021  Aldrige presented the comparison of the experimental results using a microscope and X-rays for six cement samples with the calculation results using the Bogue model. As a result, the Bogue model was calculated to be 7.1% less for alite, 1.0% less for belite, and 0.1% and 0.7% more for aluminate and ferrite, respectively.

The Bogue calculations are routinely used to estimate the quantities of the four major mineral phases in portland cements and clinkers for compliance with specifications, such as ASTM C 150.

The Bogue calculation gives low results for alite and inaccurate ones for the other phases in Portland cement clinkers, largely because the compositions of the phases differ markedly from those of the unsubstituted compounds which it assumes to be present. For a wide range of rapidly cooled clinkers produced in modern plants, the compositions of the phases are sufficiently constant to justify ...

Apr 05, 2020  Bogue’s Equations. The calculation of the potential composition of Portland cement is based on the work of R. H. Bogue and others, and is often referred to as ‘Bogue composition’. Bogue’s equations for the percentages of main compounds in cement are given below. The terms in brackets represent the percentage of the given oxide in the ...

The four compounds referred as C 3 S, C 2 S, C 3 A and C 4 AF are known as the main crystalline phases of Portland cement. The phase composition of a particular cement can be quantified through a complex set of calculation known as the Bogue formula.. Hydrated cement paste. Hydration products formed in hardened cement pastes (also known as HCPs) are more complicated, because many of

Nov 01, 2001  Known as the Bogue calculation, this continues to be an essential tool in cement plant process control to this day. Additionally, contributions of NIST scientists to our knowledge of the chemistry and nature of cement hydration products have been crucial in our understanding of cement hydration and concrete durability.
