Cement is a core construction material and a vital engineering component in food factory design, infrastructure development, and industrial facility construction. It acts as a binder that hardens, sets, and binds materials like sand and gravel (aggregate), providing strength and stability to structures.
What is Cement?
Cement is a chemical compound that undergoes a controlled chemical reaction when mixed with water, resulting in a hardened material. It is typically made from:
- Limestone, chalk, marl
- Clay, shale, slate
- Blast furnace slag, silica sand, iron ore
These materials are heated and ground to form cement that is integral in food processing unit setup, civil works, and foundation design.
Types of Cement in Construction and Food Manufacturing Facilities
Understanding various types of cement is essential for food consultants, construction managers, and engineers engaged in GMP-compliant food factory design and infrastructure projects.
1. Ordinary Portland Cement (OPC)
- Most commonly used cement worldwide
- Ideal for general concrete, mortar, and plaster
- Indian grades: 33, 43, 53
- Widely used in food processing plant foundation works
2. Portland Pozzolana Cement (PPC)
- Composed of pozzolanic material (15–35%), gypsum (4%), and clinkers
- Suitable for marine, hydraulic, and sewage structures
- Excellent for damp-prone food facilities
3. Rapid-Hardening Cement
- Gains strength quickly; used where early removal of formwork is needed
- Beneficial for fast-track food factory construction projects
4. Extra-Rapid-Hardening Cement
- Contains calcium chloride for even faster strength development
- Suitable for cold-weather construction in food plants
5. Quick-Setting Cement
- Faster setting than OPC; ideal for projects near water or requiring fast turnaround
6. Low-Heat Cement
- Low tricalcium aluminate content minimizes heat generation
- Used in mass concrete projects like retaining walls and silos
7. Sulphate-Resisting Cement
- Resists sulphate attacks from soil or water
- Used in underground food factory structures, drainage works, and retaining walls
8. Blast Furnace Slag Cement
- Economical alternative to OPC with similar properties
- Sustainable and cost-effective for green food factory design
9. High-Alumina Cement
- High strength and weather resistance
- Preferred in regions with extreme climates affecting food plant operations
10. White Cement
- Used in decorative applications like showcase food facilities
- Ideal for architectural design in food parks or retail outlets
11. Coloured Cement
- OPC blended with pigments for decorative purposes
- Used in landscaping and themed food retail environments
12. Air-Entraining Cement
- Frost-resistant; improves workability
- Ideal for cold regions where food processing plants operate in low temperatures
13. Expansive Cement
- Prevents shrinkage; useful in food plant ducts and anchor bolt grouting
14. GP-2 / Hardener Cement (Conbextra GP2)
- High early strength and density; ideal for grouting heavy machinery
- Used in industrial food processing equipment installation
15. Hydrographic Cement
- Water-repellent and high-strength
- Excellent for tanks, dams, and wastewater treatment in food industry
16. Portland-Limestone Cement (PLC)
- Contains 5–15% fine limestone
- Reduces CO₂ emissions; great for sustainable food plant engineering
Application of Cement in Food Industry Engineering
Cement is critical for:
- Food factory layout and civil foundation
- Construction of silos, drainage systems, wastewater treatment tanks
- Equipment base grouting
- Cleanroom partitions and false ceilings
- Damp-proof and thermal-resistant flooring
Professional services from food industry consultants, food processing consultants, and food plant design engineers integrate the right type of cement for each application.
