Alternative raw materials One way for Lafarge to emit less carbon dioxide (CO2) is to use alternative raw materials to replace limestone in the manufacture of cement. Derived from natural or industrial sources, such alternatives have the same properties as clinker, the main ingredient in conventional cement.
Raw materials used for manufacturing of Portland cement are found naturally in the earth crust. It is made primarily from calcareous materials, argillaceous materials and gypsum. Calcareous materials containing limestone or chalk and argillaceous materials containing an oxide of silica-alumina and iron are found as clay or shale.
Starting a cement factory in South Africa is not only a great business idea but is also an invaluable raw material to provide much needed resources to people. Maslow’s hierarchy of needs places safety on the second level, where the need for security becomes primary. We need the safety and security of a four wall concrete structure to call home.
together to make concrete. The cementitious materials dealt with in this leaflet are all based on portland cement and many contain a “cement extender.” This publication gives information on the standards that apply in South Africa to cementitious materials for concrete;
From the limestone quarry to the delivery of the end product, follow every step in the cement manufacturing process. Step 1: extraction of raw materials The raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay.
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.

There are more than twenty types of cement used to make various specialty concrete, however the most common is Portland cement. Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.
How To Work Out The Concrete Mix For Your Mould. For ease of calculation, we work by volume and not weight. Thus 250ml of oxide would be 1 cup of powder, or 5ml would be one teaspoon. If using 1 Litre of cement, use an old 1 litre bottle and fill that. Once you have measured the volume you can use any container marked with what you need to use.
