7. PRODUCTION
PROCESS
Limestone to quicklime:
-Calcium carbonate ---heat---> calcium oxide
(QUICKLIME) + carbon dioxide
-Chemical formula: CaCO3 ---heat---> CaO + CO2
Quicklime to slaked lime:
-Calcium oxide (QUICKLIME) + water ---> calcium
hydroxide (SLAKED LIME)
-Chemical formula: CaO + H20 ---> Ca(OH)2

8. PRODUCTION
PROCESS
CaC2(s) + 2 H2O(l
C2H2(g) + Ca(OH)2(s)
Calcium Carbide reacts with water
to form acetylene gas and Calcium
hydroxide (slurry).

12. DRY
SIEVING

13. SIGNIFICANCE
-Customer Requirement
-Coarser particles will choke
pipelines

14. PROCEDURE
- Weigh out 5g of sample
- Weigh the residue left on the mesh
after 10 mins of vacumn
- Calculate the percentage passing

19. WET
SIEVING

20. SIGNIFICANCE
-Determine the amount of material
finer than a given sieve size
-Used on adhesive/sticky soils

21. PROCEDURES
-Wet Sample Weighed Out
-Placed on Sieve and washed down
-Care taken to ensure accurate
results
