Trials with cement clinkers containing 5% and 10% MIBA. MIBA clinkers had chemical compositions similar to the control. Lower strengths were evident, though with less susceptibility to sulphate expansion. Lam et al. (2010, 2011) 2%, 4%, 6%, 8% MIBA in raw feed, with adjusted limestone, sand, copper slag and fly ash percentages.

2010-9-8 The process of clinker formation is described in Fig.1. The transformation concludes with the primary clinker phases [4]: Alite (C3S) is the most important constituent, 50-70% in normal Portland cement clinkers. It is tricalcium silicate (Ca3SiO5) modified in composition and crystal structure by ionic substitutions.

2020-9-26 Cement Manufacturing Process. Cement is a material which is used to bind other materials together. Binding means it has an effect of gluing the substances together due to cohesive and adhesive action and then hardens and sets in order to become permanent. Cement is usually not used on its own; it is mixed with other materials called aggregates ...

2021-11-28 Sintering: Sintering is the process of compacting and forming a solid mass of material by heat or pressure to the point of liquefaction without actually melting it. When the temperature inside the kiln reaches about 1300°C (the eutectic melting point of aluminate, ferrite and silicate), clinker flux is

Nevertheless, the clinkers usually contain some amount of free lime (up to 1-2%) and free calcium sulphate. In white cement, the whiteness index is a very important parameter to control. However, white cement contains a very low amount of iron since it decreases the whiteness, which implies insignificant content of C4AF.

New types of Cement Clinkers and the use of Mineralisers. New types of cement clinkers are being developed that are chemically different from conventional Portland cement clinker. These result in 20 – 30% CO 2 savings by reducing the amount of limestone in the formulation and because they require less energy. It should be noted, however, that ...
