INTRODUCTION
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 0.75.
Strength more than 700MPa achieved , cured at 90 degree Celsius.
FUNCTIONAL PARAMETERS
Give strength to aggregate
Maximum reactivity binding material
During heat-treating
Filling the voids
Improve ductility
Reduce water binding
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.
