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

TESTING
LAB
SIEVING
DRY
SIGNIFICANCE
-Customer Requirement
-Coarser particles will choke pipelines
PROCEDURE
- Weigh out 5g of sample
- Weigh the residue left on the mesh
after 10 mins of vacumn
- Calculate the percentage passing

COLLECTION
UNCONFINED PRESSURE TEST
SIEVING WET
SIGNIFICANCE
-Determine the amount of material finer than a given sieve size
-Used on adhesive/sticky soils
PROCEDURES
-Wet Sample Weighed Out -Placed on Sieve and washed down -Care taken to ensure accurate results
