Slag Cements; Professional Solutions for Increasing Structural Durability

Main Information

Description

Slag cements are among the best options for use in civil engineering projects with harsh environmental conditions and high durability requirements. With their special composition, this type of cement not only offers high chemical resistance but also plays an important role in protecting rebar and extending the service life of structures.

Product Technical Description

Slag Cement Collection

  • Very low permeability: Prevents the penetration of water and salts into the concrete structure, avoiding long-term damage.
  • Higher workability and smoother surface: The presence of silica in the composition of slag cement gives concrete a uniform texture and improves its adhesion.
  • High chemical resistance: Exceptional resistance to simultaneous attack from chloride and sulfate makes this cement suitable for corrosive areas.
  • Rebar protection: Preventing rust and corrosion of reinforcement bars is one of the most important features of this cement.
  • Low heat of hydration: Helps avoid cracking due to heat generation in mass concrete projects.
  • Reduces concrete porosity: Leads to increased density and durability of the structure.

Applications of Slag Cement

Slag cement is used in projects where durability, chemical resistance, and protection against corrosion are of great importance, including:

  • Areas with chloride and sulfate salts
  • Mass structures such as dams and reservoirs
  • Wharfs, ports, and coastal facilities
  • Tunnels, subways, and underground lines
  • Waterways, canals, and underground piping
  • Reinforced concrete and resistant structures
  • Tropical areas with high temperatures
  • Projects with alkali-silica reactive aggregates

Important Notes on Using Slag Cement

If your project requires quick formwork removal or involves minor concrete pouring, you should consult technical experts before using slag cement as its performance may differ from that of ordinary cements.

Conclusion: Slag Cement

Slag cement, with its combination of advantages such as high resistance against chemical agents, reduced heat from hydration, and high durability, is an ideal choice for structures that must remain resilient in harsh environmental conditions.
