Abstract
Concrete, which combines cement, water, aggregates, and admixtures to create a flexible material that
solidifies into stone-like strength, is the foundation of contemporary building. Because of its versatility,
it can be used for anything from pavements to skyscrapers, but typical mixes require large amounts of
cement, which increases manufacturing costs and CO2 emissions. This study investigates the use of
Alccofine 1203, a powder made from ultrafine slag, as a partial substitute for cement in M60 high-
strength concrete at 0%, 5%, 10%, 15%, and 20% levels. The experiments used OPC 53 cement, river
sand, crushed stone (20 mm maximum size), and superplasticizer for ideal flow, all in accordance with
IS 10262–2009 mix design. Important tests included flexural (9.6 MPa max), split tensile strength,
compressive strength on cubes (peaking at 74.48 MPa for 10% mix at 28 days), and workability (slump
up to 118mm, compaction factor 0.99). Results demonstrate that 10% Alccofine improves workability
and reduces cement consumption for greener projects while increasing early and long-term strength by
27% over control mixes through tighter packing and pozzolanic reactions. With research supporting
8–15% for peak performance, this dose is ideal for demanding applications like bridges and towers.
Keywords: Alccofine 1203, compressive strength, flexural strength, m60 concrete, pozzolanic reaction, split tensile strength
