In this experimental research is focused on the utilization
of phosphogypsum as a partial replacement of cement in concrete. The main aim
was to experimentally analyze the strength and durability characteristics of
concrete with the addition of phosphogypsum and comparing it with the
conventional concrete mix. In this phosphogypsum is added to a 0%, 5%, 10%, 15%
and 20% by partial replacement of cement with M25 grade of concrete with water
cement ratio 0.45. The fresh and harden concrete properties was tested for
slump test , compaction factor test, while the hardened concrete for
compressive strength, split tensile, flexural strength and water absorption
test different replacement levels at the age of 7 and 28 days obtained. The
experimental results shows that the maximum replacement level of 15% with
weight of cement. Beyond limits of increasing replacement level of cement
strength will be reduced.
