Reactive power concrete (RPC) is:
- A composite material of ultra high quality with mechanical properties.
- Mixture of fiber strengthened, super plasticized, silica rage, bond and quartz sand with low water concrete proportion.
- Quartz sand utilized rather than normal total. Thus, these lines increments compressive quality.
Composition
- It is made out of comparative modulus of flexibility and size expanding homogeneity decreasing differential elastic strain.
- The material having the biggest molecule measure in RPC is the sand.
- The higher the thickness, the more noteworthy the quality and lower the porousness.
- Water bond proportion utilized as a part of RPC reaches from 0.15 to 0.25
- Strength more than 200MPa accomplished, cured at 90 degree Celsius.

Characteristics of Reactive Powder Concrete
- Compact Strenth
- Higher compressive strength than HPC
- It is a factor connected with toughness of substance.
- Highest compressive force of RPC is roughly 200MPa.
- Flexural Strength
- Plane RPC has maximum flextural strength than HPC
- By bringing forward steel fibers, RPC can attain high flextural strength.
- Water Absorption
- Water Permeability
- Resistance to Chloride Ion Penetration
- Expands when heat curing is done in solid
- Heat cured RPC show greater value than normal cured RPC.
- Homogenity
- enhanced by removing all coarse aggregates.
- Dry materials for use in RPC is lesser than 600 micro meter.
- Compactness
Appliance of pressure before and while concrete setting period.
- Microstructure
Microstructure of the cement hydrate could be altered by putting heat treatment while curing.
Application
- Sherbrooke Pedestrian Bridge
- Containment of nuclear waste:
- Used for separation and repression of nuclear wastes.
- It has been used for jamming & stabilization of repression waste.
Advantages
- It can possibly basically rival steel.
- Superior quality consolidated with higher shear limit result in critical dead load lessening.
- RPC can be utilized to oppose everything except direct essential tractable anxiety.
- Improved seismic execution by diminishing dormancy stack with lighter part.
- Low &non-interconnected porosity decreases mass exchange, making infiltration of fluid/gas non-existent.
Disadvantages
- Least overpriced parts of routine cement are wiped out by more costly components.
- RPC supplants steel in pressure individuals where sturdiness issues chance. So long haul properties are not yet known.
