Al Saeed Low Heat Portland Cement

El Saeed cement is a low heat of hydration cement; It is the result from crushing a dry mix made of clinker and gypsum.


The reaction between cement and water generates heat of hydration not more than 250 Kj/Kg after 7 days.


Uses and applications

It can be used in all types of constructions.
It is suitable for concrete elements of large cross sections (mass concrete).
Suitable to be used in the hot weather.


Advantages

  • 1. It gives high final compressive strength (28 days).
  • 2. It gives more workability for the concrete.
  • 3. It reduces concretes cracks.
  • 4. Suitable to be used in hot weather.
