our company was founded in 2002 in Yemen and has a large stock of rawmaterials such asmarble 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 materials1-Natural GypsumGypsum 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 Gypsum2-Salt is used to drill oil wells3-Calcium carbonate is in large quantities and we export to some Asian countries4-rocks Pozzolana which are used inABOUT NATURAL POZZOLANANatural Pozzolana can be used in the grinding process with cement clinker tomanufacture blended Pozzolana Portland Cement &＃39;PPC&＃39;. Here it can replace about30% of clinker.Natural Pozzolana can also be ground finely by itself to say 4,000 Blain andused directly in the cement concrete mix where it can substitute cement.Substituting 30% Portland cement with fine natural pozzolana will accomplishthe following:1. Lithification2. Autogenous healing3. Improves Fatigue properties4. Reduces permeability and voids5. Reduces expansion and heat of hydration6. Reduces creep and cracks7. Reduces micro-cracking8. Increases compressive strength9. Increases resistance to chloride10. Increases resistance to sulfate attack11. Reduces alkali-aggregate reaction12. Impedes carbonation13. Reduces freeze-thaw damage14. Protects steel reinforcement from corrosion15. Increases abrasion resistance16. Lowers water requirement with high fluidity, self-leveling andself-compression17. Improves durability18. Reduces costs of production and construction19. Increases production capacity and reduces energy requirements andcosts20. Reduces carbon dioxide emissions21.
