Description

Gharb Cement Clinker Type 2: A Reliable Choice for Durable and Resistant Structures

Overview
Gharb Cement Clinker Type 2 is one of the flagship products of Gharb Cement Industries Company located in Kermanshah Province, Iran. As the main raw material for the production of Type II Portland cement, this clinker is manufactured with a precise formulation and advanced quality control. It is specifically designed to provide high resistance to sulfates, generate low heat of hydration, and significantly enhance the durability of concrete in moderately aggressive environments.

Chemical Composition
According to the official laboratory report of Gharb Cement Company and based on the Iranian National Standard (ISIRI 389), the main chemical constituents of this clinker are:
SiO₂ (21.5%), Al₂O₃ (5.4%), Fe₂O₃ (4.1%), CaO (65.7%), and MgO (2.0%).
The high CaO content and optimal silica ratio promote the formation of strong silicate phases, which result in high compressive strength in the produced cement. Furthermore, the low levels of SO₃ and Free CaO (approximately 1.25%) ensure chemical stability and prevent unwanted expansion in concrete.

This balanced composition produces a dense, uniform clinker structure that meets global standards in terms of oxide composition and quality consistency.

Mineralogical Phases and Structure
Mineralogical phase analysis shows that Gharb Cement Clinker Type 2 contains approximately 61.88% C₃S and 15% C₂S. This composition ensures high early-age strength while maintaining long-term durability.
The controlled C₃A content (7.37%) enhances resistance to sulfates and other aggressive agents, while the C₄AF phase (12.47%) contributes to improved color and physical stability.

Quality indices such as LSF (94.89), SM (2.26), and AIM (1.32) indicate an optimal balance of raw materials and oxides, which has a direct impact on the final cement quality.

Quality Control and Production Standards
Gharb Cement Industries produces its Clinker Type 2 using state-of-the-art technology, intelligent control systems, and a fully equipped laboratory. Every stage, from raw material preparation to rotary kiln firing and rapid cooling, is supervised by experienced engineers with continuous monitoring of all technical parameters.

The company holds international certifications such as CE, ISO 9001, and ISO 14001. All products undergo ongoing testing for chemical composition, mineral phases, and physical performance. This strict quality control ensures exceptional product stability and uniformity.

Technical Advantages and Features

• Excellent Sulfate Resistance:
  The controlled C₃A content allows the clinker to perform exceptionally well in sulfate-rich or chemically aggressive environments.
• Low Heat of Hydration:
  The reduced heat release during cement setting prevents cracking in massive concrete structures.
• Compatibility with Additives:
  Gharb Cement Clinker Type 2 is fully compatible with additives such as pozzolans, slag, and plasticizers, improving both the mechanical strength and durability of concrete.
• Stable and Uniform Quality:
  The precise mineral composition and uniform crystalline structure ensure consistent performance in cement production.

Applications and Export Market
Due to its superior quality and stable composition, Gharb Cement Clinker Type 2 is widely used in the production of general-purpose and pozzolanic Portland cements. It is ideal for large-scale construction projects, dams, marine structures, bridges, and industrial foundations.

Thanks to its strategic location in Kermanshah, Gharb Cement enjoys easy access to export markets in Iraq, Syria, Turkey, and the Persian Gulf region. Consistent quality, standard packaging, and reliable delivery have established it as one of Iran’s most trusted clinker export brands.

Conclusion
Gharb Cement Clinker Type 2 represents a perfect blend of technical expertise, mineral quality, and precision manufacturing. With its high sulfate resistance, low heat of hydration, and stable mineral phases, it stands among the top choices for producing premium cement in Iran and across the region.

Leveraging its modern infrastructure, strategic location, and rigorous quality standards, Gharb Cement Industries Company has solidified its reputation as one of the leading producers of Type II clinker in the Middle East.
