About Cement

Cement is a ubiquitous material that plays a crucial role in the construction industry. It is a fine, powdery substance that, when mixed with water, forms a paste that hardens and binds together various building materials, such as sand, gravel, and stone. Cement is essential for the construction of buildings, bridges, roads, and walls. Its versatility, durability, and strength make it an indispensable component in the modern built environment. From the foundations of skyscrapers to the sidewalks beneath our feet, cement has and continues to play a vital role in building the world.

Properties of Cement

One key property of cement is fineness, which refers to the size of cement particles typically ranging from 3 to 30 micrometres. Finer cement particles result in increased surface area, leading to faster hydration, and higher early strength. Soundness is another important property, ensuring low expansion or contraction after setting, with a maximum allowable expansion of 0.8% as per standard specifications. Moreover, cement has a compressive strength ranging from 20 to 60 MPa (3,000 to 8,700 psi) and tensile strength around 10% of the compressive strength. Cement’s setting time is also low, and it has a bulk density, typically between 1,200 to 1,600 kg/m³, which is important for transportation and storage considerations. These physical properties collectively determine the suitability and performance of cement for various construction applications.

Manufacturing Process of Cement

The cement manufacturing process begins with the extraction of raw materials, such as limestone, clay, and sand, from quarries. These materials are then transported to the cement plant for analysis of proportion required to make cement, which is typically 80% limestone and 20% clay. The raw mix is then ground into a fine powder using heavy wheel-type rollers and a rotating table.

Next, the raw material passes through a series of vertical cyclones in the pre-heater chamber, using the hot gases emitted from the kiln. The raw material is then heated up to 1450°C in the rotating kiln, causing chemical reactions and forming a slurry. The primary constituents of cement, calcium silicate, are formed through reactions between calcium and silicon dioxide compounds. Fuel, such as natural gas and coal, is used to heat the kiln from the exit side, and the material forms the shape of clinker as it reaches the lower part of the kiln. The clinkers are then cooled and grounded into a very fine powder. Finally, the cement is conveyed to silos from the grinding mills and packed into 20-40 kg bags, while the remaining cement is shipped in bulk quantities by trucks, rails, or ships.

Process of Making Cement

The manufacturing of cement involves several key processes, such as:

Step 1. Raw Material Extraction

The primary raw materials used in the production of cement are limestone, clay, and sand. Limestone is the source of calcium carbonate (CaCO₃), clay provides silica (SiO₂), alumina (Al₂O₃), and iron oxide (Fe₂O₃), while sand contributes additional silica.

Step 2. Preparation

The extracted raw materials are crushed, ground, and mixed in the correct proportions to create a homogenous mixture known as raw meal.

Step 3: Heating (Clinker Production)

The raw meal is fed into a rotary kiln where it is heated to about 1450°C (2640°F). This process results in the formation of clinker, which consists of various compounds such as tricalcium silicate (3CaO·SiO₂), dicalcium silicate (2CaO·SiO₂), tricalcium aluminate (3CaO·Al₂O₃), and tetracalcium aluminoferrite (4CaO·Al₂O₃·Fe₂O₃).

• Calcination: CaCO₃ (s) → CaO (s) + CO₂ (g)

• Formation of dicalcium silicate: 2CaO (s) + SiO₂ (s) → 2CaO·SiO₂ (s)

• Formation of tricalcium silicate: 3CaO (s) + SiO₂ (s) → 3CaO·SiO₂ (s)

• Formation of tricalcium aluminate: 3CaO (s) + Al₂O₃ (s) → 3CaO·Al₂O₃ (s)

• Formation of tetracalcium aluminoferrite: 4CaO (s) + Al₂O₃ (s) + Fe₂O₃ (s) → 4CaO·Al₂O₃·Fe₂O₃ (s)

Step 4: Cooling and Grinding

The hot clinker is rapidly cooled using air to stabilise the compounds. The cooled clinker is mixed with a small amount of gypsum (CaSO₄·2H₂O) and ground into a fine powder to produce cement. The gypsum acts as a set retarder, controlling the setting time of the cement.

Step 5: Packaging and Distribution

The final cement product is packaged in bags or stored in silos for distribution to construction sites and other customers.

Applications and Drivers of Cement

Cement is used extensively in both residential and non-residential construction projects. It is also used in various infrastructure projects such as road construction, dam construction, commercial establishments, industrial structures, stadium construction, and transportation hub construction. Government initiatives such as housing schemes, construction of hospitals and educational facilities, and development of transportation infrastructure contributes to the demand for cement. It is also used in mining and oil exploration activities in the Middle East and Africa. Moreover, the increasing adoption of green cement for constructing eco-friendly and sustainable buildings is a growing trend in the market, which is promoting market’s growth.
