2. Introduction
 Called as porous concrete, permeable
concrete, no fines concrete.
Porous Concrete Is a special type of
Concrete composed of gap graded
aggregate, low or no fine aggregate and
binded by cementitious material.
It has high porosity which allows water to
pass through it, reducing the runoff from
side and allowing the ground water
recharge.

3. History
1st use in 1800s in Europe as pavement surfacing and load
bearing walls.
It become viably in Europe after the second world war due to
scarcity of cement
Popular in US after 1970s
Limited use in India

4. Mix Design Composition
Aggregates
Cementitious material
Water
Admixture

5. Aggregates
Mostly contain Coarse Aggregate
of size, range 10mm-20mm
little or no fine Aggregate
Fine aggregate can be substitute
by rice husk

6. Cementitious
Material
Generally OPC cement is used considering
environmental effect
Partially cement can be replaced by other
cementitious materials like fly ash(upto
25%) or slag(upto 50 %).
Ground Granulated Blast-Furnace Slag gives
higher strength but lower porosity relative to
fly ash.

7. Water & Admixture
Casting and curing is done with potable water(free from salt &
impurities) conforming to the IS 10500 : 2012
Generally low water content is preferred
Different researcher have taken w/c in the range of 0.3 to 0.4
Admixture is used to increase workability of concrete eg.
Masterplast plasticizer with 0.2% of weight of cement
 Chyrso Plast Delta D780 plasticizer is used to reduce
water content

8. Application
Parking area
Court yard
Residential road
Low volume pavement, Drive way
Tennis court, Summing pool decks
Side walk

9. Advantages
 Reduce the storm water runoff
 Ground water recharge
 Replens is water table and aquafer through ground water
recharge
 Minimises flash flooding and extending water
 Light reflectivity is higher then the asphalt surface
Environmental Benefits
 Low construction and maintenance cost
 More life span
 Light reflectivity is higher then the asphalt surface,
reduces glare
 Prevents slipping and skidding, reduces chances of
accident
Economics
Safety

10. Disadvantages
To prevent reduction in permeability, frequent maintenance by
vacuum sweeping and pressure washing is required but effectiveness
and implementation is questionable
Low compressive strength
Limited use in heavy vehicle traffic area
Porosity is reduced over a long time due to clogging

12. Literature Review
1. Navya (2015) developed an innovative model that can transport water pass into
the pavement for which M20 grade concrete with a w/c ratio of 0.4 to 0.45, coarse
aggregate of nominal size 20 mm and with a cement to coarse aggregate ratio of
1:4 was adopted
Its density and flexural strength were observed to be 21 kN/m3and 35
kg/cm2respectively.
He conlcuded that the pavement slab is suitable for low traffic volume roads and
designed as per IRC SP62: 2004 which allows storage of water upto 125 lit./m3of
concrete pavement giving time for infiltration, thereby reducing the runoff and
recharging the ground water or sufficient time for transport of it.
Further, he suggested perforated pipe can be provided at center of the pavement
above sub-base such that it collects the water stored in concrete.

13. 2.
Ali et al (2010) optimized mix design of pervious concrete includes pumice
aggregate (grain size between No. 4 ∼ No. 3/8” sieve), W/C (0.25), A/C (4),
100 Kg Portland cement per cubic meter of concrete, silica fume (5.05
percentage of cement weight), zeolite (5.45 percentage of cement weight),
iron oxide (0.5 percentage of cement weight), and superplasticizer (0.11
percentage of cement weight).
Verification of samples indicated 69% Ni removal, 84.5% Cu removal and
the compressive strength of 2 MPa and permeability coefficient of 1.6 cm/s.
Literature Review

14. 3.
Alaica et al. (2010) performed an experiment to optimize pervious
concrete mix was achieved using aggregate size of 10-13mm, cement
to aggregate to ratio of 1:4 and a ternary cementing blend of silica
fume and slag.
Testing of tensile strength revealed that the addition of wollastonite
and polypropylene fibers improved the strength of the paste)
Literature Review

15. 4.
Lee et al. (2016) evaluated the mechanical characteristics and durability of porous
concrete produced with a cementless binder based on ground granulated blast
furnace slag (BFS), fly ash (FA) and flue gas desulfurization gypsum (CP).
The result showed, the void ratio was increased slightly from the target void ratio,
by 1.12–1.42 %. Compressive strength of porous concrete with cementless binder
decreased in comparison to the compressive strength of porous concrete with
ordinary Portland cement (OPC), but the difference was insignificant, at 0.6–1.4
MPa.
Through the freeze–thawing test to evaluate the durability, it was found that the
relative dynamic elastic modulus of porous concrete with cementless binder
decreased to 60 % or less at 80 cycles.
Literature Review

16. 5.
Patil et al (2014) in his paper stated water permeability of the common
concrete pavement is low and the rainwater is not filtered underground
due to which plants are difficult to grow normally.
This maked difficult for soil to exchange heat and moisture with air.
Therefore, the temperature and humidity of the earth's surface in large
cities cannot be adjusted which leads to hot island in city.
During rainy days flash on the road reduces the safety of traffic of vehicle
and foot passenger
Literature Review

17. 6.
Hesami et al. (2014)published a paper named, “Effect of Rice Husk and Fibre on
Mechanical Properties of Pervious Concrete Pavement‟.
Coarse aggregate sized from 2.36 to 19.0 mm, RHA of 0%, 2%, 4%, 6%, 8%, 10%
and 12% weight percentage as a cement replacement, PPS fibre 0.3%, steel fibre 0.5%
and glass fibre 0.2% are to remain constant at 3 different w/c ratio of 0.27, 0.33 and
0.40.
The compressive, tensile and flexural strength were found to be maximum at w/c ratio
of 0.33.
For 10% replacement of RHA and w/c ratio of 0.33, the compressive strength of
pervious concrete containing fibres increases by 34%, 37% and 36% respectively for
glass, steel and PPS fibres.

.Kuo et al. (2013) have studied the utilization of washed municipal solid waste
incinerator bottom ash(MSWIBA) as a coarse aggregate in pervious concrete.
In the present study washed municipal solid waste incinerator bottom ash
(MSWIBA) was used as aggregate in pervious concrete. Various mechanical
properties such as permeability test, compressive strength,
Various mechanical properties such as permeability test, compressive strength,
tensile strength of the material were carried out.
The test results show that the unit weight of the MSWIBA was lies between 1653–
2080 kg/m3 .The tensile and bending strengths were approximately 1/9 and 1/4 of
the compressive strength respectively
Literature Review

19. 8.shah et al. (2013) published a research paper „Pervious Concrete:
New Era for Rural Road Pavement‟ in 2013. Object of the study was
to evaluate the cost effectiveness of the pervious concrete compared
to normal concrete.They conclude that the pervious concrete reduce
the storm water runoff to increase the ground level water to eliminate
the costly storm water management practices. And there is
considerable saving in amount about 29rs/m3 or 18rs/ft2
