QUICK LIME LUMPS 10-80 MM

Quicklime (Calcium Oxide – CaO)
Other names: Burnt Lime, Calcined Lime, Unslaked Lime
Manufacturer: Vietnam Technology Mineral JSC

 

Description:
Quicklime is produced by heating high-quality limestone (CaCO₃) in a kiln at elevated temperatures, causing it to undergo calcination:
Reaction: CaCO₃ → CaO + CO₂

When water is added, quicklime reacts vigorously in an exothermic process called slaking of lime, releasing intense heat. It has a strongly alkaline pH (~12.5), making it highly caustic — proper safety measures are essential when handling.

Key Specifications:

  • CaO content: ≥ 90% for premium-grade quicklime

  • Particle size: Fine particles (<1 mm) for higher surface area & faster reactivity

  • Moisture content: ≤ 1–2% to maintain reactivity

  • Impurities: MgO ≤ 2.5%; negligible heavy metals (Pb, As)

  • Consistency: Uniform particle size, density & reactivity across batches

  • Reactivity: Fast, exothermic slaking; ideal setting time ~24 hours

  • Storage stability: Maintains quality for 6–12 months with proper storage

  • Source traceability: Controlled limestone sourcing & kiln operation for consistent quality

Production Advantage:
Quicklime produced in modern rotary kilns offers superior and more consistent quality compared to older fixed-grate kilns.
