Al Fanar Cement

A type of Portland cement that generates moderate quantity of heat of hydration and moderate sulphates and chloride salts resistance.


The scientific concept of Al Fanar Cement is to comply with the standards of Modified Portland Cement Type II (ASTM C150 / 2007 ) by reducing the final total content of Tri-Calcium Aluminates and Tri-Calcium silicate phases as it hydrates generating bigger quantity of heat of hydration.

Also the controlling of Tri-Calcium Aluminates to enable cement to have good resistance against Sulphate (with average concentration 150 – 1500 part per million) and in the same time have a good resistance against chlorides. As the increasing in Tri-Calcium Aluminates reducing concrete ability to resist sulphate and increase the resistance to chlorides.

Al Fanar Cement complies with the following two conditions:

  1. Tri-Calcium Aluminates content is in between 5 % to 8 %.
  2. The sum of content of (Tri-Calcium Aluminates and Tri-Calcium silicate) phases (C3S + 4.75 C3A) is not more than 100 ,this is to control the heat of hydration to be not more than 70 Calorie /gm or 290 K.j /kg of cement, this after 7 days of hydration.

Uses and applications

Generally, Al Fanar (Type II) Cement is recommended for mixing concrete in the media of double exposure to sulphates and chloride ions such as substructures and superstructures subjected to seawater attack. In addition, it is suitable for concrete elements of large cross sections (mass concrete).


Advantages

  • 1. Moderate heat of hydration that reduces cracks even in mass concrete.
  • 2. Balanced moderate Resistance of sulphates and chlorides.
  • 3. It gives relatively moderate early compressive strength after7 days.
  • 4. It gives high final compressive strength (28 days).
  • 5. It gives a relatively delayed setting time and may reduce the needed dosage of concrete admixtures.

Shelf time

It is recommended to retest the cement after 6 weeks since the production date.


Safety recommendations

It is recommended to follow the coming instructions:

  • Avoid the contact of the cement with the eyes and the skin since it may cause allergic reaction.
  • Use gloves and glasses to protect hands and eyes in case of spray applications, or manual mixings.

How to clean the cement remains of the used tools

  • Before setting: by using clean water.
  • After setting: by using mechanical methods.

Environment concept

It is advised and recommended to follow local environmental instructions.
