The resultant product in nodular form obtained from the kiln is called clinker. Clinker is immediately quenched in the clinker cooler to stabilize its properties and stored in the clinker stockpile. 3. Cement production. Cement is produced by grinding clinker with 3-5% gypsum in a closed circuit ball mill to required fineness.

The presence of heavy metals in the clinker arises both from the natural raw materials and from the use of recycled by-products or alternative fuels. The high pH prevailing in the cement porewater (12.5 < pH < 13.5) limits the mobility of many heavy metals by decreasing their solubility and increasing their sorption onto the cement mineral phases.
Use as alternative raw material in cement production Clinker: Fly ash from coal-fired power plants can be used effectively as a component of raw kiln feed for the manufacture of cement clinker. Fly ash contains significant amounts of Al 2 O 3 and SiO 2 and has thus been used as a partial replacement of natural raw materials like clay and/or shale in the raw kiln feed.
Depending on the purities of the raw materials available at the manufacturing site, Portland cement production may require additions of bauxite as a source of alumina and laterite as a source of iron oxide. The relative oxide content of Solidia Cement and Portland cement are compared in the ternary CaO-SiO 2-Al 2 O 3 diagram in Figure 1.

Raw material substitution In Brief. 60% of the industry’s emissions are ‘process emissions’ caused by decarbonation of limestone during the production process.
The raw meal composition depends on (i) the purity of limestone and clay (ii) the targets of LSF, SM, AM modules. For pure raw materials - limestone with low content of clay, clay with low content of CaO and an LSF≈96, an average raw mix composition is ~80% limestone and ~20% clay.
Raw Materials White clinker contains the same phase assemblage as grey clinker - alite, belite, tricalcium aluminate, tetracalcium aluminoferrite and a little free calcium oxide - but the tetracalcium aluminoferrite, which is the only dark coloured phase, is minimised.
Summary of production process. Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions.

Alite is the characteristic constituent of Portland cement.Typically, a peak temperature of 1400–1450 °C is required to complete the reaction. The partial melting causes the material to aggregate into lumps or nodules, typically of diameter 1–10 mm.
Concrete is a hardened building material created by combining a chemically inert mineral aggregate (usually sand, gravel, or crushed stone), a binder (natural or synthetic cement), chemical additives, and water.

Consistent quality feed is required and an extraction plan must be made to ensure that a uniform flow of raw material will always be available to the kilns. 2.2 Cement making.
In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter, produced by sintering (fused together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

The initial production step in portland cement manufacturing is raw materials acquisition. Calcium, the element of highest concentration in portland cement, is obtained from a variety of calcareous raw materials, including limestone, chalk, marl, sea shells, aragonite, and an impure limestone known as "natural cement rock".
