Cement - Wikipedia

Green cement is a cementitious material that meets or exceeds the functional performance capabilities of ordinary Portland cement by incorporating and optimizing recycled materials, thereby reducing consumption of natural raw materials, water, and energy, resulting in a more sustainable construction material. One is Geopolymer cement.

Portland cement - Wikipedia

The most common use for Portland cement is in the production of concrete. Concrete is a composite material consisting of aggregate (gravel and sand), cement, and water.As a construction material, concrete can be cast in almost any shape desired, and once hardened, can become a structural (load bearing) element.

cement | Definition, Composition, Manufacture, History ...

This article surveys the historical development of cement, its manufacture from raw materials, its composition and properties, and the testing of those properties. The focus is on portland cement, but attention also is given to other types, such as slag-containing cement and high-alumina cement.

How Cement Is Made

The finely ground raw material or the slurry is fed into the higher end. At the lower end is a roaring blast of flame, produced by precisely controlled burning of powdered coal, oil, alternative fuels, or gas under forced draft. As the material moves through the kiln, certain elements are driven off in the form of gases.

Composition of cement

Composition of cement. Introduction Portland cement gets its strength from stone reactions between the cement and water. The process is known as hydration.This is a complex process that is best understood by first understanding the stone composition of cement.

Fly Ash as a Portland Cement Raw Material

For the domestic industry, the use of fly ash as a raw material in cement manufacture is still practically an untapped market. During the manufacture of the various types of portland cement, one or more raw materials must be blended to achieve proper stone composition in the kiln feed.

Raw materials for cement manufacturing

The second important raw material for cement production is clay.The main component of clay is formed by hydrous aluminium silicates.The stone composition of clay may vary from those close to the pure clay, to that containing a significant amount of admixtures as iron hydroxide, iron sulfide, sand, calcium carbonate, etc. Clay is used as an ...

Cement - History of cement | Britannica

Raw materials Composition. Portland cement consists essentially of compounds of lime (calcium oxide, CaO) mixed with silica (silicon dioxide, SiO 2) and alumina (aluminum oxide, Al 2 O 3).The lime is obtained from a calcareous (lime-containing) raw material, and the other oxides are derived from an argillaceous (clayey) material.

RAW MATERIALS IN CEMENT PRODUCTION

The main materials used in cement production are minerals containing calcium oxide, silex, alumina and iron oxide. These components are rarely found in one type of raw material; therefore, for the cement production the raw mix is selected for the following components:
