Al Fanar Cement Type II

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 / 2012) 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. 
  • Controlling of Tri-Calcium Aluminates to enable cement to have good resistance against Sulphate (with average concentration 150 – 1500 part per million) and at 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:

  • Tri-Calcium Aluminates content is in between 5 % to 8 %.
  • 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 KJ /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

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

Packaging:

  • Bags: 50 Kg/bag.
  • Jumbo plastic bags: 500 Kg/bag, 1000 Kg/bag, 1500 Kg/bag.
  • It is also available in bulk.

Storage

It is recommended to follow the following instructions:

  • Storage should be done in a dry place and away from ground moisture.
  • It is preferable to store on wooden bases.
  • Cement should be covered to avoid the rain.
  • It is recommended not to pile up any more than ten bags.

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.

Health effects

  • Inhalation: May cause respiratory irritation. Repeated exposure to cement can cause damage to the lungs.
  • Skin contact: Causes severe burns and may cause an allergic skin reaction.
  • Eye contact: Causes serious eye damage.

First-aid measures

  • Eye Contact: Flush the eyes with plenty of water and seek medical doctor advice.
  • Skin Contact: Wash the skin with natural soap and water, use moisturizing cream, then consult medical doctor.
  • Ingestion: Do not vomit or drink large amount of water and seek medical doctor advice.
  • Inhalation: Move person to fresh air area, if the person is not breathing, make CPR (artificial respiration), and if there is difficulty in breathing, provide person with oxygen and seek medical doctor.

How to clean the cement remains of the used tools

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