In this study, to reduce the use of cement and sand, porous feldspar with excellent economic efficiency was used as a substitute in the heat storage concrete layer.

Portland cement is made up of clinker, finely ground powder, firing clay, and limestone in a kiln. The process involves blending, crashing, and heating the raw materials that create the clinker. Cement manufacturers then grind the clinker and make it into a fine powder while adding gypsum to control the setting time.

The higher SO3 in the Portland cement clinker also prevented the autoclave expansion in case of high MgO limestone. it has been observed that in case of 5 per cent MgO containing clinker if the SO3 is 2.17 per cent the autoclave expansion is 0.44 per cent. ...

Extraction and Preparation of Raw Materials. The main raw materials (limestone, clay chalk or basalt) are quarried from natural rocks. They are crushed and transferred to pre-blending storage where other substances (such as sand, iron ore, bauxite, shale, slag, fly ash) are added to get the desired chemical composition.

A number of phases are formed in the clinker feed before the burning zone proper is reached. These intermediate phases dissociate in the burning zone and are not therefore found in clinker but assist in forming the final clinker minerals. Sulfate melt phase At intermediate temperatures, sulfates combined with calcium and alkalis form a liquid ...

More recently, over the past 200 years, clays are also used in the cement industry for Portland cement clinker manufacture. Although calcined clay bricks are also fired at high temperatures (950–1200 °C), the calcined clays discussed in this article are those materials used as SCMs; the difference is that, unlike for fired bricks, calcined ...

For example, Turkey and Egypt currently use modest amounts of secondary CMs (clinker-to-cement mass ratios of 0.75 and 0.86 in 2018, respectively) and have …

In the manufacture of Portland cement clinker, the kiln feed and fuel contain some minor constituents that are volatile in nature. ... The potash content in kiln feed is generally higher than the soda content unless some unusual raw materials like industrial wastes are used in kiln feed preparation. (iii) Alkalies are contributed by both ...

India has plenty resources of feldspar, so it could contribute to the attempt for indigenous production of potash fertilizer. Feldspar possesses a silicon–oxygen–aluminum tetrahedron in which potassium is placed in the interstitial sites to balance the charge of the matrix.6,7 Other potassium-containing aluminosilicate …

The prospect of using cement clinker dust (CKD) as an additive in recovering potash values from an Indian mica scrap sample, containing 7.64% potash, is explored. It is found that the clinker dust, mostly treated as solid waste in the cement industry, can act as the calcium source in the chloridizing roasting of mica.

This study aims to determine the effect of adding 10% basalt rock and coal variations as a limestone substitution in cement clinker manufacture. Coal is obtained from the Tanggamus district with the variations used, namely 5, 10, 15, and 20% outside the total mass. Raw materials such as limestone, silica stone, clay, basalt stone, coal, and ...

Fluorspar is added to help the combination of the kiln feed into the white cement clinker so reducing the fuel (pet coke) consumption of the kiln. Feldspar is added to correct the alkali:sulphate balance in the kiln. Petcoke is high in sulphur so the …
