Special, CEM II / A-M (S-V) 42.5N
Special contains at least 80% of Portland cement clinker; up to 20% mixed additive, combination of blast furnace slag (S) and silicon fly ash (V); up to 5% by-product (filler); bonding regulator (natural gypsum). The combination of the amount and type of admixture provides it with the required strengths, while producing concrete it gives good workability and increases chemical resistance with reduced heat of hydration over pure Portland cement.
