Manufacturing process | Lafarge in South Africa

This process involves removing unwanted materials, such as blocks, clay, etc The scalped product is crushed once to transform the block into broken stone The process is repeated as many times as necessary to obtain the desired fragment size The resulting material is then screened to obtain aggregates of the desired grade...

The Cement Manufacturing Process

The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement The powdered cement is then mixed with water and aggregates to form concrete that is used in construction Clinker quality depends on raw material composition, which has to be closely monitored to ensure the quality of the cement Excess free lime ....

Aggregate in Concrete

Both gravel and crushed stone are generally acceptable for making quality concrete (Photo 9), although gravel is usually preferred for exposed aggregate The use of recycled concrete, crushed to proper-size concrete aggregate, has also demonstrated successful performance...

Aggregates

Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation...

Blast Furnace Slag

Blast Furnace Slag - Material Description ORIGIN In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product...
