3. Introduction
Reactive powder concrete (RPC) is the generic name for a class of
cementious composite materials developed by the technical division of
Bouygues, in the early 1990s. It is characterized by extremely good
physical properties, particularly strength and ductility
A composite material & ultra high strength with mechanical properties.
Mixture of cement, silica fume, quartz powder, steel fiber(Optional) &
super plasticized with a very low water cement ratio.
This compactness gives RPC ultra-high strength and durability.
Reactive Powder Concretes have compressive strengths ranging from
200 MPa to 800 MPa.
4. •Chard and Cheyrezy indicate the following principles for developing RPC:
• Elimination of coarse aggregates for enhancement of homogeneity
•Utilization of the pozzolanic properties of silica fume
•The optimal usage of super plasticizer to reduce w/c and improve workability
•Post-set heat-treatment for the enhancement of the microstructure
•Addition of small-sized steel fibers to improve ductility
5. Composition of RPC
• Components :- Function parameters
1) sand :- To increase bulk volume
2) cement :- Binding material
3) Quartz powder :- Maximum reactivity during heat-treating
4) Silica fume :- Filling the voids
5) Steel fiber :- Improve ductility
6) Superplasticizer :- Reduce water binding
6. Application of RPC

U.S.
Sherbrooke pedestrian bridge, in Canada
7. Need of study
• To study the civil engineering applications of industrial byproduct like
foundry sand, which is technically sound and is environmentally safe.
• To study the use of Foundry sand as a partial replacement of Fine
Aggregate to achieve different property of concrete.
• To study the use of Fly ash as a replacement of Quartz powder and
partial replacement of Cement.

The incorporation of silica fume in
RPC matrix remarkably enhances
the steel fiber–matrix bond
characteristics due to the
interfacial-toughening effect upon
fiber slip.

1. The maximum compressive
strength of RPC obtained in the
present study is 146 MPa at
w/b ratio of 0.2 with accelerated
curing.
2. In the production of RPC the
optimum percentage addition of
silica fume is found to be
15% (by weight of cement) with
available superplasticizer.
3. The addition of quartz powder
increases the compressive strength
of RPC up to 20%
4. The high temperature curing is
essential for RPC to achieve higher
strength. It increases
the compressive strength up to 10%
when compared with normal curing.

•the duration of the heat treatment
influences the form of the structure
and quality of crystal formation.
•Increased heat-treatment
temperature leads to the
development of longer C–S–H
chain.
• when the heat-treatment
temperature
increases, the compressive strength
increases owing to
C–S–H crystal formation, thereby
improving the
microstructure behaviour.

The fly ash used in these
investigations exhibits good
Pozzolanic properties and can be
used in the production of high
strength high volume fly ash
concrete. High volumes of fly ash
up to 50% can be used as additional
material without sacrificing strength
at lower w/b ratios.
12. Objective of Study
• The main objectives of this experimental work is to study the effect of
industrial byproduct like foundry sand and fly ash in the Reactive
Powder Concrete on its various properties.
• To understand the waste utilization scenario of the foundry type
industrial byproduct in India.
• To ascertain the behavior of RPC mixed with foundry sand and fly ash,
thereby, examining the changes of properties like strength and ductility.
13. Scope of Study
• Foundry sand is used for the preparation of RPC.
• Steel fiber is introduced to improve ductility.
• Super plasticizers of different qualities are used to study their effects on the
workability and compressive strength of Reactive Powder Concrete.
• Silica fumes of different qualities are used to study their effects on the
compressive strength of Reactive Powder Concrete.
• Steel fibers of two different dimensions are used to compare the change in
compressive strength.
