Decartelization is the transition of a national economy from monopoly control by groups of large businesses, known as cartels, to a free market economy. This change rarely arises naturally, and is generally the result of regulation by a governing body with the authority to decide what structures are permissible.
This template has been created for transclusion in the articles Concrete, Cement, and Silica fume. It replaces the file at right. That file had been tagged for translation to SVG format, as if it were a graphic. But since it is really a table, I have re-rendered it in wiki markup.
The Lafarge scandal refers to the court case against Lafarge, a French cement company, for making payments to the armed terrorist groups Islamic State of Iraq and Levant and al-Nusra Front between 2013–2014. [1] The scandal was first revealed by French journalist Dorothée Myriam Kellou and was then followed by investigations by the French ...
But under article 15(6) the immunity would not apply after the Commission informed undertakings of their preliminary examination. The Noordwijk Cement companies got a letter under article 15(6) saying their immunity ceased, and it brought an action to quash the decision. The Commission argued their decision was not an ‘act’ that could be ...
Cement hydration and strength development mainly depend on two silicate phases: tricalcium silicate (C 3 S) , and dicalcium silicate (C 2 S) . [1] Upon hydration, the main reaction products are calcium silicate hydrates (C-S-H) and calcium hydroxide Ca(OH) 2, written as CH in the cement chemist notation. C-S-H is the phase playing the role of ...
Calcium silicate hydrate (also shown as C-S-H) is a result of the reaction between the silicate phases of Portland cement and water. This reaction typically is expressed as: 2 Ca 3 SiO 5 + 7 H 2 O → 3 CaO · 2 SiO 2 · 4 H 2 O + 3 Ca(OH) 2 + 173.6 kJ. also written in cement chemist notation, (CCN) as: 2 C 3 S + 7 H → C 3 S 2 H 4 + 3 CH + heat
Calcite cement in an ooid-rich limestone; Carmel Formation, Jurassic of Utah. Minerals bond grains of sediment together by growing around them. This process is called cementation and is a part of the rock cycle. Cementation involves ions carried in groundwater chemically precipitating to form new crystalline material between sedimentary grains ...
