The document discusses a study on utilizing rice husk ash as a partial replacement for cement in pervious concrete. Various mix designs were tested with 10%, 20%, and 30% rice husk ash replacements by weight of cement to study the impact on compressive strength and water absorption over 7 and 28 days. The results of the testing were compared to a control mix to analyze the effects of rice husk ash incorporation.

2. Introduction
 Rice Husk Ash (RHA) is an agricultural
waste product which is globally every year
and difficulty involved in it’s disposal, can
RHA becoming an environmental hazard in
rice producing countries.
 India alone produces around 120 million
tons of rice paddy per year, giving around
6 million tons of rice husk ash per year.
 RHA can be used in concrete to improve its
strength and other durability factors.
 So we can use RHA as a partial
replacement of cement in pervious
concrete.

3.  In this research (OPC) cement has been
replaced by RHA accordingly in the range
of 10%, 20% and 30% by weight of cement
for constant 0.40 water cement ratio.
 The compressive strength test and water
absorption test was carried out for 7, 28
days.
 So the main aim of the investigation to
study the behavior of Pervious Concrete
while replaces the RHA with different
proportions in concrete.
 The test results were obtain from the
research which are compared with the
control mix (CM)produced in large
quantities.

Pervious
Concrete:
New Era
For Rural
Road
Pavement
pervious concrete pavement in
rural areas becomes more
suitable to meet the rural area
requirement such as to reduce
the storm water runoff, to
increase the ground water level,
to eliminate the costly storm
water management practices
Pervious concrete is the
relatively new concrete for the
pavement construction in rural
areas having cost benefits and
pervious concrete extensively
used worldwide because of their
environmental benefits,
hydraulic and durability
properties.

Study of
Pervious
Concrete
Compressive strength of
pervious concrete depend
upon the porosity of
concrete ,age, binder
material (type of
cement),test specimen
shape and size showed
huge influence on the
strength of pervious
concrete .
Compressive strength is
inversely proportional to
porosity hence, when
compressive strength
increases porosity
decreases

Effect of Rice
Husk Ash on
Properties of
Pervious
Concrete
 W/C ratio is increase
respectively compressive
strength and flexural
strength of pervious
concrete is increase.
 The Compressive
Strength of Concrete is
increases up to 10%of
Cement with RHA beyond
than it is starting to
decrease.
 The Flexural Strength of
Pervious Concrete is
increases up to 10%
replacement of Cement
with RHA beyond than it is
starting to decrease.
 It is the possible
alternative solution of safe
disposal of RHA.

8. Materials
Cement: The Ordinary Portland Cement of 53
grade conforming to IS: 12269 - 1987 is been
used. Specific gravity 3.15, normal consistency
28%, Initial and final setting time 30 min and
600 mins.
 Rice Husk Ash: Specific gravity of rice hush
ash 2.30, particle size < 90 microns, shape
irregular, color black.

9.  Coarse Aggregate: Aggregate occupies most
of the volume of the concrete show they are the
important constituents of concrete. They give
body to the concrete, reduce shrinkage and
effect economy. Two sizes of aggregate were
used in this research work. Coarse aggregate
used in the study were sieved to obtain required
range.
The physical properties of aggregate are shown in
below table:
Property Aggregate
20mm 10mm
Fineness Modulus 7.52 3.19
Specific Gravity 2.75 2.65

10. Water: Water is an important
ingredient of concrete as it actually
participates in the chemical reaction
with cement. Since it helps to from the
strength cement gel, the quantity and
quality of water are required to be
looked into very carefully.
