RAW MATERIALS FOR CEMENT MANUFACTURING Mechanical

The alkalis in the raw meal are Sod. & Pot. oxides which originate from clay or marl. These evaporate in the rotary- kiln burning zone and cause the so-called alkali-circulation. Also, certain concrete aggregates contain opal which reacts with the alkalis of cement and thereby result in expansion phenomena.

Raw materials Understanding Cement

Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.

Compositional Analysis of Cement Raw Meal by Near-Infrared

Abstract. A rapid and accurate method is presented to determine CaCO 3, SiO 2, Fe 2 O 3, and Al 2 O 3 in cement raw meal using near-infrared (NIR) spectroscopy. Multiplicative scatter correction (MSC) was employed to eliminate the scattering signal and partial least squares (PLS) regression was used to build the analysis model.
