Concrete: Manufacturing Process. A good quality concrete is essentially a homogeneous mixture of cement, coarse and fine aggregates and water which consolidates into a hard mass due to chemical action between the cement and water. Each of the four constituents has a specific function. The coarser aggregate acts as a filler.

Stage of Cement Manufacture. There are six main stages of the cement manufacturing process. Stage 1: Raw Material Extraction/Quarry The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale, and bauxite. The ore rocks are quarried and crushed into smaller …
Cement Manufacturing Process. Cement is a material which is used to bind other materials together. Binding means it has an effect of gluing the substances together due to cohesive and adhesive action and then hardens and sets in order to become permanent. Cement is usually not used on its own; it is mixed with other …

The second diagram shows that cement can be used to produce concrete. This process is simpler than cement production; concrete is a mixture of 15% cement, 10 % water, 25% sand and 50 % small stones which are named as "Gravel". The four elements are poured in a huge mixer which rotates producing concrete.
cement manufacturing process flow chart Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.
4. Speed Reduction. At this stage of cement hydration, the temperature reaches its maximum level, and free particles are now reduced, thus slowing the rate of temperature rise. This stage usually complete with the required strength, and the concrete formwork can be removed now.
In this kiln there are 3 different zones shown in fig. below. Cement Manufacturing Process Flow Chart. (i) Drying Zones: In the wet process, the drying zone is comparatively larger than the dry process. It is because the raw material in slurry form is directly fed into the kiln which has more amount of water.
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).
