Cement is the most used construction material in Pakistan. It is an essential construction material. Without cement, you cannot build a house. Nowadays, the rate of cement is increasing daily, and it is becoming challenging for builders to make houses. In this article, I will discuss the cement price in Pakistan today, 2022.
What is Cement?
Cement is a construction material that is used to solidify the material together. Cement is in the form of powder. It is a combination of different substances. With the cement, you can bind the stones and bricks together.
Cement made up of
Cement comprises different substances such as limestone, clay, aluminum, and iron. It includes many other materials such as shells, clay, shale, and furnace blast.
Types of Cement
There are many types of cement worldwide, but we will discuss some of its essential types.
Hydraulic cement
Hydraulic cement combines different substances such as limestone, clay, and gypsum. This type of cement hardens in the existence of water.
Non Hydraulic cement
This is a different type of cement. It doesn’t need water to get solidify. It reacts with carbon dioxide to make things happen.
Ordinary Portland Cement (OPC)
It is mainly used cement in construction works. This type of cement consists of two materials like aluminum and iron. It also contains calcium silicate. It is used primarily in masonry works.
Portland Pozzolana Cement (PPC)
It is a natural type of cement with a large amount of Silica in a reactive shape. Its composition consists of different substances such as OPC, gypsum, volcanic ash, etc.
Raw Materials
Portland cement is made up of crucial compounds of Lime blended with aluminum and Silica. Raw materials like Silica, sand, iron oxide(composed of iron and oxygen), and bauxite(it’s a reddish clay material known as laterite soil)
Hold hydrated aluminum possibly used in a trivial amount to obtain a demanded composition. Calcareous and argillaceous raw materials are also used in making cement.
Calcareous raw materials are limestone, chalk, coral, and shell deposits.
Argillaceous raw materials are Clays, shales, estuarine muds, and slates.
Gypsum: 5% gypsum is added during grinding. Gypsum is used to control the setting time of cement.
Both Marl ( a fine-grained mineral) and Cement Rock hold the properties of argillaceous and calcareous components.
One more raw material is blast furnace slag, Which contains mainly Lime, Silica, and alumina and is assorted with calcareous material. Kaolin, a white clay, holds a little iron oxide, used as argillaceous material to obtain white Portland cement.
Industrial wastes are raw materials used in smaller quantities, such as fly ash and calcium carbonate, obtained from chemical manufacturing.
The combined process with Sulphuric Acid uses calcium sulfate and anhydrite in place of calcium carbonate to make Portland cement. Flue gases on burning give sulfur dioxide, which is changed to sulphuric acid by a simple process.
Manufacture of cement:
The manufacturing process of cement consists of wet and dry processes, and it depends on the following factors
Physical conditions of the material
Condition of the factory
Plus the price of the fuel.
Wet process: in the wet process, raw materials are crushed and mixed in the presence of water to make a Slurry.in Pakistan, different factories use a wet process
Dry process: in the dry process, raw materials are mixed in the absence of water and sent into the kiln.
There are four stages in the manufacturing of cement
Firstly crush and grind the raw materials
Secondly, blend the raw materials
Burn the mixture in a kiln
Grind that burned product
Then add 5%of gypsum to it
Crushing and grinding process:
Raw materials are firstly crushed into a suitable state, often in two stages, and then ground in the presence of water, generally in rotating cylindrical balls or tube mills carrying a charge of steel balls.
Blending the raw material:
The powdered limestone is mixed with the clay paste in a proper proportion (75% limestone and 25% clay) and then ground properly.
The final mixture is called slurry, and the slurry contains 35 to 45% water, frequently strained to reduce the water content from 20 to 30%, and the filler cakes are reserved in storage bins—this lower the fuel consumption for the heating stage.
Burning the mixture in a kiln:
The prepared slurry is fed into the rotatory kiln. the rotatory kiln consists of a large cylinder
12 to 15 feet in diameter and 300 to 500 feet in length. It is constructed of steel and is lined inside the firebricks. The kiln rotates horizontally on its axis at 1-2 revolutions per minute.
Whenever the kiln rotates, charges start moving downward. Heating the bills by using natural gas, burning coal, and oil now these charges passed through the different temperature zones. Orders take 2-3 hours to complete the process.
Grinding the clinkers:
The clinkers are then air-cooled then the desired amount of fine powdered gypsum is added to the clinkers. At this point, the finished cement expands to the storage soils from where the glue is transmitted to the paper bags.
