Description

Urmia Cement — A Reliable Choice for High-Quality and Fast Construction Projects

Cement is one of the most important building materials, playing a critical role in the durability, strength, and quality of structures. Urmia Cement, Ordinary Portland Cement CEM I 42.5 R, is one of the prominent and standard products in the Iranian cement industry. It is produced in compliance with the international standard EN 197-1, offering precise chemical composition, stable performance, and uniform quality, making it an ideal choice for a wide range of construction and industrial projects.

Chemical Properties of Urmia Cement

✅ SiO₂: 20.67% — contributes to strength and cohesion, and plays a key role in cement hydration.
✅ Al₂O₃: 4.89% — accelerates setting time and improves performance under varying environmental conditions.
✅ Fe₂O₃: 3.09% — enhances initial strength and stability, contributing to the final product quality.
✅ CaO: 63.56% — essential for high strength and stable hydration.
✅ MgO: 1.7% — controlled levels reduce the risk of cracking and undesirable expansion.
✅ SO₃: 2.54% — controls initial and final setting times to prevent premature or delayed setting.
✅ K₂O: 1.11% and Na₂O: 0.23% — controlled alkali content prevents alkali-silica reaction in concrete.
✅ Loss on ignition: 2.08% and Free lime: 1.25% — indicate stability and controlled performance under high temperatures.

This precise chemical formulation ensures that Urmia Cement performs reliably not only in domestic projects but also in industrial and export applications requiring high-quality standards.

Physical and Mechanical Properties

⚡ 2-day compressive strength: 32.5 MPa — ensures fast initial strength for projects requiring quick load bearing.
⚡ 7-day compressive strength: 45 MPa and 28-day compressive strength: 55 MPa — guarantees the concrete can withstand heavy loads and environmental pressures.
⚡ Initial setting time: 115 minutes and final setting time: 165 minutes — provides ample working time for placement, pouring, and compaction without premature setting.
⚡ Autoclave expansion: 0.05% — minimal expansion ensures dimensional stability and reduces cracking risk.
⚡ Soundness (Le Chatelier): 0.5 mm — high stability against volumetric changes, maintaining mold shape.
