Advances in Cement Technology | ScienceDirect

Recycling of concrete materials also offers some promise. Attempts are already being made to use municipal refuse and waste oil as partial substitutes for fuel in the production of cement clinker. The chapter presents some of the ways in which various waste materials and by-products may be used in concrete technology.

Cement

There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement).

Cement Additives

It is common to use cement additives that increase the mechanical strength by chemical activation, without changing the cement surface and particle size distribution. Alkanolamines are frequently used and are able to increase the compressive strength (at different or all age) by max. five MPa. Typical examples are SikaGrind®-200 and SikaGrind ...

Industry 4.0

In cement production, it pays off to be an early adopter of new technology. Industry 4.0 will reduce costs, increase the bottom line, and even help attract and retain talent. Boston Consulting Group recently published a report highlighting five areas where cement producers can benefit from Industry 4.0, so we called them up for a talk on the ...

Portland Cement Manufacturing Industry: National Emission ...

 · Portland cement manufacturing is an energy intensive process in which cement is made by grinding and heating a mixture of raw materials such as limestone, clay, sand, and iron ore in a rotary kiln. The kiln is a large furnace that is fueled by coal, oil, gas, coke and/or various waste materials.
