3.  Worldwide there is increasing demand for construction and
construction material, for that concrete is most extensively used.
 There are many advantages of concrete, but one of the drawback
is that, it is not flexible.
 To overcome this drawback a new construction material is in
evolution called concrete cloth (cc).
 Concrete cloth is a ground breaking technology that allows
concrete to be used in a completely new ways.

4.  The technology was first found for emergency shelters,
believed that it may not be commercialized to commercial
construction work.
 But further research in the concrete cloth made incredible
changes in the construction field.
 the British engineering company had found the
revolutionary material called concrete cloth.
 This revolutionary new material takes its own place in the
history of civil engineering.

5.  It is a flexible cement-impregnated fabric that hardens when
hydrated to form a thin, durable concrete layer.
 Concrete Cloth™ (“CC”) consists of:
- Dry concrete mix
- Reinforcing fiber matrix
- Fabric top surface
- PVC bottom coating

6. 1. Strength
Very high early strength is a fundamental characteristic of
concrete cloth.
 Compressive testing
This test based on ASTM C473 – 07
- 10 day compressive failure stress 40 N/mm2
- 10 day compressive Young’s modulus 1500N/mm2
 Bending test
This tests based on BS EN 12467:2004
- 10 day bending failure stress 3.4N/mm2
- 10 day bending Young’s modulus 180N/mm2

8. 1.Subgrade preparation
 CC will conform closely to the underlying surface contours therefore
any vegetation and sharp or protruding rocks should be removed.
 Compacted and smooth subgrade should be prepared prior to placement
of Concrete Cloth.

9. 2.Concrete cloth placement
 Over lapping method is followed
 The fibrous top surface faces upwards
 PVC layer is placed at the bottom , in contact with the
ground
 This layer is water resistant and prevent subsequent
hydration.

10. 3.Cutting of concrete cloth
 Concrete cloths are cut to a specified length after
installation or to conform to the installation area.
 It is designed to be cut with commonly using cutting
tools.
10

11. 4. Anchoring
 After installation concrete cloth they are anchored to
the subgrade.
 Soil nails or soil anchors, screws, thermal welding are
used.

 Slope protection
 Pipeline protection
 Mining application
 Bund lining
 Concrete canvas shelter

13.  Portable -Easily transported and deployed without specialized
equipment
 Rapid– the material can be hydrated either by being sprayed
or by being fully immersed in water. Once hydrated, it remains
workable for four hours and hardens to 80% strength within
24 hours. This time can be reduced by adding accelerants into
the dry mix at the point of manufacture.
 Easy to use– dry concrete cloth can be cut or tailored busing
simple hand tools .It can be easily repaired or upgraded using
existing cement products.

14.  Concrete cloth (CC) is a unique proprietary material.
 It is a time & material saving technique. It is very easy to
place & handle.
 Concrete cloth is a flexible; cement impregnated fabric
that hardens when hydrated to form a thin, durable, water
& fire proof concrete layer.
 CC allows concrete construction without the need for
plant or mixing equipment. Simply position the canvas &
just add water.
 CC has a design life of 10 years and is significantly
quicker and less expensive to install compared to
conventional concrete.
 It is specially used , where the workmanship is very
difficult.
 It is specially used in emergency works such as in military.

16. Reliance Chairman Mukesh Ambani
announced the JioPhone - “digital independence”
to all Indians.
Some Guidelines are given in order to get
JioPhone for free.
The one-time deposit amount Rs 1,500 is
needed which will be refunded to its customers
after 3 years on returning the phone. This means
the phone will be available at an effective price of
zero.
The pre-booking for the phone starts August will
be available in September on first-come first
serve basis.
The JIO Phone comes with the Internet
connectivity, follows voice commands, and
recognises 22 Indian regional languages.
