Composite Cement CEM V/B is a sustainable blended cement defined by EN 197-1. It contains 20–38% clinker, 31–50% blast furnace slag or pozzolana + fly ash, and 0–5% minor additional constituents. Its low clinker content reduces CO₂ emissions while providing excellent durability, sulfate resistance, low heat of hydration, and superior long-term strength. CEM V/B is ideal for marine structures, dams, bridges, tunnels, mass concrete, and other demanding infrastructure projects.
