Reactive Powder Concrete is a developing composite material that will allow the concrete industry to optimize material use, generate economic benefits and build structures that are strong, durable and sensitive to environment.RPC is an ultra high strength and high ductility cementitious composite with enhanced physical and mechanical properties. It was first developed in the early 1990?s by Bouygue?s laboratory in France. It consists of a special concrete where its microstructure is optimized by pre ....etc

REACTIVE POWDER CONCRETE


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 partic ....etc

Reactive Powder Concrete


What is it?
What does it do?
What is its applicability?
What kind of research is being done on it?
Why should we care?
Where is it headed?

Current High Strength Concrete

High performance concrete can be made to have strengths in excess of 30,000-40,000 psi.

Use either a mix of superplasticizer, silica fume, and extra-hard aggregate (calcined bauxite or granite) or Macro Defect Free polymer pastes

Still brittle, low ductility

IMPROVEMENT OF CONCRETE DURABILITY BY COMPLEX MINERAL SUPER-FINE POWDER



Introduction
Coal gangue is a rock included in the coal bed and a waste discharged during coal
mining and transportation as well as the most industrial waste discharged in China. It
is estimated , that the amount of gangue calculated as 15% of the coal output,
there would be 100 million ton increment annually. Most of the coal gangue is a clay
rock; its main mineral composition consists of clay min ....etc

Reactive Powder Concrete (RPC) is a developing composite material that will allow the concrete industry to optimize material use, generate economic benefits, and build structures that are strong, durable, and sensitive to environment. A comparison of the physical, mechanical, and durability properties of RPC and HPC (High Performance Concrete) shows that RPC possesses better strength (both compressive and flexural) and lower permeability compared to HPC. This page reviews the available literature on RPC, and also presents the results of laborat ....etc
