INTRODUCTION
A composite material & ultra high strength with mechanical properties.
Mixture of fiber reinforced, super plasticized, silica fume, cement & quartz sand with very low water cement ratio.
Quartz sand used instead of ordinary aggregate. Therefore increases compressive strength.
COMPOSITION
It is composed of similar modulus of elasticity and size increasing homogeneity reducing differential tensile strain.
The material having the largest particle size in RPC is the sand.
The higher the density, the greater the strength & lower the permeability.
Water cement ratio used in RPC ranges from 0.15 to 0.25
Strength more than 200MPa achieved , cured at 90 degree celsious.
. FLEXTURAL STRENGTH
Plane RPC possess high flextural strength than HPC
By introducing steel fibers, RPC can achieve high flextural strength
HOMOGENITY
Improved by eliminating all coarse aggregates.
Dry components for use in RPC is less than 600 micro meter.
. CONTAINMENT OF NUCLEAR WASTE
Used for isolation and containment of
nuclear wastes.
It has been used for blocking &
stabilization of containment waste.
CONCLUSION
It has immense potential in construction due to its superior, mechanical &durability properties.
RPC has ultra dense micro structure , giving advantageous water proofing &durability characteristics.
