Within the cement and concrete industry, blended cement is an important category designed to enhance the properties of cement by incorporating one or more supplementary cementitious materials (SCMs) with Portland cement. This amalgamation can include materials like fly ash from coal combustion in power plants, ground granulated blast furnace slag from steel production, silica fume from the production of silicon or ferrosilicon metals, and natural or industrial pozzolans. Blended cements offer various advantages over ordinary Portland cement, such as improved workability, increased long-term strength, reduced permeability, and better resistance to aggressive environments.
These enhancements correspond to more durable concrete structures and a reduction in the carbon footprint associated with cement production. Blended cements are widely used in various types of construction, including residential, commercial, infrastructure, and industrial projects. The modifications to the original properties of cement through blending also respond to diverse geographical and climatic requirements, making them essential for terrain-specific constructions. Furthermore, their use aligns with the industry’s effort to adopt more sustainable practices by utilizing industrial byproducts and reducing clinker content, thus conserving resources and lowering emissions.
Prominent companies operating within the blended cement market include LafargeHolcim, CEMEX, HeidelbergCement, CRH plc, Buzzi Unicem, SCG, UltraTech Cement, Votorantim Cimentos, InterCement, and Dalmia Bharat Limited. These enterprises operate across various regions, providing a wide Show Less Read more
