Reactive powder concrete (RPC) is one of the
most recent and significant advancements in the world of
building. Due to its higher concrete characteristics, it has
a common excessive benevolence happening in the globe
at the moment, excessive ductility, shrinkage resistance,
and corrosion and abrasion resistance. The approach to
revising the RPC is investigated experimentally in punching
shear slab action and the properties of construction
material to investigate properties of Volumetric ratios of
steel fiber, and silicas fume, tensile steel ratio, the most
important component for construction is reinforced concrete,
which works well with other materials to create
structures in any shape that is needed. In the present
research, investigational work of RC slab with (1000 ×
1000 × 60) mm, dimensions was tested. This study aims
to see how the relative volume of steel fibers (Vf) and silica
fume content (Sf) affect the actions of RC slabs after
being exposed to Fire. It originated that a concrete mix
containing 2% steel fibers improved the RPC slab’s cracking
and final punching shear. The existence of reactive
powder increases fire resistance. This study’s experiment
aimed to see how reactive powder and Slab’s ultimate
punching shear strength was affected by replacement ratio.
When exposed to Fire. After fire exposure, the initial
and subsequent stiffness of reinforced concrete slabs reduced
considerably as the temperature grew from 25 to
750 ∘C.
