Recycled materials: often of industrial origin, from demolition, recycled concrete, railway ballast, etc. Deposits of alluvial aggregates are increasingly rare, having already been largely exploited. They are gradually being replaced by marine aggregates, an excellent alternative material. The geological nature of marine aggregates is identical
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.
Calcium Carbonate (CaCO 3): As the key ingredient in cement manufacturing, Calcium Carbonate accounts for 70-80% of the raw meal, and is known as Limestone.; Silicon Dioxide (SiO 2): Silicon Dioxide makes up a total of 10-15% of the raw meal.Its source is mainly Silica sand. Aluminum Oxide (Bauxite Al 2 O 3): Accounting for up to 5% of the raw meal, Aluminum Oxide is sourced from clay and

Manufacturing process Lafarge in South Africa Cement, concrete . Manufacturing process. In theory, producing aggregates simply involves crushing rock. In practice, it is much more complex, as standardized sizes and homogenous
Slag Cement. Lafarge NewCem® is a supplementary cementitious material (SCM). It can be used in tested quantities to enhance the desired properties of concrete. Slag. Slag is produced during the iron-manufacturing process. During the manufacturing process the materials are heated in a blast furnace to a molten state.
Aggregates Portland Cement Association. Aggregates strongly influence concrete's freshly mixed and hardened properties, mixture proportions, and economy. Consequently, selection of aggregates is an important process. Although some variation in aggregate properties is expected, characteristics that are considered include: grading; durability
