Crushed Limestone Industrial Applications
Sigma Minerals supplies Crushed Limestone for processing, manufacturing, construction, neutralization, soil treatment, and mineral applications. Consistent chemistry and controlled size fractions support dependable performance across multiple industries.
Lime Manufacturing
Used as the primary raw material for producing Quick Lime and Hydrated Lime, where high CaCO₃ and low impurities support better finished-product quality.
Cement Industry
Used as a major raw material in cement manufacturing to form calcium silicates and aluminates during clinker production.
Mineral Filler
The 0–6mm fraction is used in asphalt, concrete, coatings, and bituminous mixes to improve workability and control mix properties.
Construction Aggregate
The 6–25mm and 25–50mm sizes are used in concrete, road base, sub-base, and general infrastructure applications.
Glass Industry
Provides Calcium Oxide during glass melting, helping improve chemical resistance, hardness, durability, and weatherability.
Steel Industry
Used as a flux material to react with silica and alumina impurities, supporting slag formation and cleaner steelmaking.
Agriculture
Applied as agricultural lime for gradual soil pH correction, calcium improvement, and long-term soil productivity.
Road Construction
Used in pavement base and sub-base layers where controlled gradation and reliable load-bearing performance are required.
