Sohail Company for Mining and Oil Services

Company Description

our company was founded in 2002 in Yemen and has a large stock of raw
materials such as
marble and Granite
We have several quarries of marble and granite in more than
one area in Yemen
Are exported to some countries in the form of stones (blocks)
And equipped and
re-exported nearly the quality of Italian
marble

(Please scenes attached files)


And we have anther raw materials

1-Natural Gypsum

Gypsum is known to chemists as calcium sulphate di-hydrate (CaSO4 - 2H2O).

used in making of:

1- Cements manufacture
2- White Cement.
3- Plaster of Paris.
4- Plaster Wall.
5- Agriculture Gypsum

2-Salt is used to drill oil wells

3-Calcium carbonate is in large quantities and we export to some Asian countries

4-rocks Pozzolana which are used in

ABOUT NATURAL POZZOLANA

Natural Pozzolana can be used in the grinding process with cement clinker to
manufacture blended Pozzolana Portland Cement 'PPC'. Here it can replace about
30% of clinker.

Natural Pozzolana can also be ground finely by itself to say 4,000 Blain and
used directly in the cement concrete mix where it can substitute cement.

Substituting 30% Portland cement with fine natural pozzolana will accomplish
the following:

1. Lithification
2. Autogenous healing
3. Improves Fatigue properties
4. Reduces permeability and voids
5. Reduces expansion and heat of hydration
6. Reduces creep and cracks
7. Reduces micro-cracking
8. Increases compressive strength
9. Increases resistance to chloride
10. Increases resistance to sulfate attack
11. Reduces alkali-aggregate reaction
12. Impedes carbonation
13. Reduces freeze-thaw damage
14. Protects steel reinforcement from corrosion
15. Increases abrasion resistance
16. Lowers water requirement with high fluidity, self-leveling and
self-compression
17. Improves durability
18. Reduces costs of production and construction
19. Increases production capacity and reduces energy requirements and
costs
20. Reduces carbon dioxide emissions
21. Unifies quality
