Hydrated Lime
Widely used in construction and chemical processing, Hydrated Lime improves workability, plasticity, water retention, and bonding in mortars and plasters, while providing alkaline neutralization in environmental applications.
Product Overview: High-Calcium Hydrated Lime
Hydrated Lime (Calcium Hydroxide, Ca(OH)₂) is a dry, refined alkaline powder produced through the controlled hydration of high-calcium quicklime (CaO + H₂O → Ca(OH)₂). Revered in construction, civil engineering, water treatment, and chemical processing, it delivers unmatched workability, plasticity, water retention, and adhesive bonding in mortars, plasters, and masonry systems.
Its ultrafine colloidal particle sizing and alkaline nature (pH 12.4) impart cohesive, buttery troweling mixes that resist premature water loss against porous brickwork. In environmental and chemical processes, it provides potent neutralization for acidic effluents, flue gas desulfurization (FGD), soil stabilization, and potable water purification.
Key Benefits
Improved Workability
Enhances ease of spreading, troweling, and placement in mortar and plaster systems.
Better Water Retention
Helps control moisture loss against porous brickwork, ensuring complete binder hydration.
Good Bonding Support
Improves cohesion and mechanical keying in masonry and plaster substrates.
High Alkalinity
Provides potent pH adjustment and neutralisation capacity for chemical and effluent treatment.
Good Reactivity
Enables rapid, complete reaction kinetics in environmental and chemical processes.
Durability Support
Contributes to self-healing carbonation and long-term weather-resistant construction performance.
Applications
Construction Mortars & Wall Plasters
Soil Stabilization & Road Bases
Water & Wastewater Neutralisation
Flue Gas Desulfurization (FGD)
