Quick Lime
Thermally calcined quicklime lumps and powder with high available lime content for steel fluxing, AAC blocks, paper, and wastewater treatment.
Product Overview: High-Reactivity Quick Lime
Quick Lime (Calcium Oxide, CaO) is an inorganic chemical compound produced by the thermal decomposition (calcination) of high-grade limestone in state-of-the-art vertical shaft kilns.
Known for its high reactivity, high available lime content (CaO ≥ 85–90%), and low slaking time, Sakthima Quick Lime is widely used as a flux in steel making, pH neutralizer in water treatment, and chemical reactant in AAC block manufacturing.
Key Benefits
Efficient Steel Fluxing
Acts as a basic flux to remove phosphorus, silica, and sulphur impurities during basic oxygen and electric arc steelmaking.
Essential for AAC Blocks
Reacts vigorously with aluminium powder to generate hydrogen aeration and optimal thermal insulation in lightweight concrete blocks.
Water & Effluent Treatment
Rapidly neutralizes acidic industrial wastewater, precipitates heavy metals, and aids in biological sludge conditioning.
Paper Pulp Causticizing
Enables efficient causticizing of green liquor in kraft paper mills for chemical recovery loops.
Soil Stabilization
Reacts with clay soils in highway and sub-base construction, drying waterlogged ground and increasing load-bearing capacity.
Applications
Steel & Metallurgy Fluxing
AAC Lightweight Concrete Blocks
Industrial Wastewater Treatment
Paper Pulp Mills
