FINAL REVIEW
4. Project Focus
PERMEATION PROPERTY OF
THE CONCRETE
Permeation
gasses and
water can be
happened by
three distinct
Phenomena
1) Permeability
2) Absorption
3) Diffusion
5. Project Focus
PERMEATION PROPERTY OF
THE CONCRETE
Flow property of concrete
under a pressure
differentiation
The process by which
the concrete takes in
the liquid by capillary
action
The processes by
which a vapour gas or
ions can pass through
concrete by a
concentration gradient
Permeability
Absorption
Diffusion
6. Project Conceptual
Plan
Cease the penetration of Water and
Gasses
SURFACE COATING : Already track
proven technology is available in the market.
WATER PROOFED
CONCRETE : Lot of research
are still going on..

Conclusions
7. PHASE - 1
The technology used is NANA-
TECHNOLOGY.
Nano Technology is the study of very
minute atoms or molecular structure
– Monomer.
METHODOLOGY: Formulating a
hybrid cement which has a water
repellent property once it get
hardened.
Selection of monomer: - Basically
silicon is an element which have high
water repellence and crack bridging
property. Hence Silicon as a base
element interlinked with monomer.
POLYSILOXANES - This siloxane
based monomer contains alkyl unit.
Water repellence, acid resistance and
heat resistance.

MIX DESIGN – M40
As a bench mark, M40
grade concrete has been
taken as base.
This mix will be altered by
adding different percentage
of monomer - 1%, 2%,
3%,4% etc.
