Cement

Brief Introduction:
Cement is one of the most essential building materials, used as a binder in construction. Typically produced as a gray powder, it hardens when mixed with water, turning into a durable and solid material. Cement is widely used in the production of concrete, mortar, and other construction products.

Product Category:
Cement falls under the category of mineral and construction materials.

Applications:

1. Construction Industry:
   • Cement is a fundamental material used in building structures, bridges, dams, roads, and other infrastructure.
2. Concrete Production:
   • Cement is a key ingredient in concrete, which is used for making columns, walls, and foundations.
3. Mortar Production:
   • When mixed with sand and water, cement is used to produce mortar for bonding bricks and blocks.
4. Soil Stabilization:
   • Cement is employed in civil engineering projects to stabilize soft soils and improve their load-bearing capacity.

Scientific Properties:

• Chemical Composition: Mainly consists of lime (CaO), silica (SiO₂), alumina (Al₂O₃), and iron oxide (Fe₂O₃).
• Specific Gravity: 3.15 g/cm³
• Melting Point: Over 1,400°C

Consumption Barriers:

• Moisture: Cement should not be exposed to moisture, as it can clump and lose its quality.
• Heavy Duty Uses: For high-strength applications, specialized cement with enhanced technical properties should be used.

Hazards:

• Skin and Eye Irritation: Direct contact with cement can cause irritation, inflammation, or chemical burns.
• Dust Exposure: Inhaling cement dust may lead to respiratory problems.

Standards:
Cement must conform to international standards such as ASTM C150 or EN 197 to ensure its strength and durability in construction applications.

Storage Conditions:
Cement should be stored in a dry, cool, and moisture-free environment. Exposure to damp conditions can cause the cement to harden and form clumps, reducing its effectiveness.
