I hope this presentation related to the topic Pervious Concrete by one of my friends, may be useful to someone.

4. Pervious concrete was first used in the
1800s in Europe.It became popular
again in the 1920s for two story homes
in Scotland and England. It became
increasingly viable in Europe after the
Second World War due to the
scarcity of cement. It did not become as
popular in the US until the 1970s.

5. Pervious Concrete:
 PCPC is composed of portland cement, coarse aggregate, water, and admixtures.
 lack of fine aggregate causes the concrete to have a void structure.
which allows liquids and air to pass through the concrete and into a sub-base

6. APPLICATIONS:
Sidewalks
Parking Areas
Residential
Flatwork
Drainage Areas
Courtyards

7. Should We Use Pervious Concrete:
• Green Building alternative suitable for many applications
• Natural run-off allows rainwater to drain directly to sub-base
• Reduced construction requirements for drainage structures
• Reduced pollution prevents environmental damage
pervious concrete as a Best Management Practice (BMP), and
building owners and designers are realizing more efficient
land utilization while acquiring LEED credits through the use
of pervious concrete structures.

8. i. The addition of a small amount of sand will
increase the Strength. water to cement ratio
0.28 to 0.40 with a Void content of 15 to 25 %
ii. This allowes proprerty owners to develop a
large areas of available property at a lower cost
iii. Pervious concrete also naturally filters storm
water and can reduce pollulant load in the
streams,ponds and rivers

9. Placing Pervious Concrete
Jointing Pervious Concrete
Curing Pervious Concrete

10. Getting Started
Pervious Concrete is a very design dependent mixture and
should achieve a 15-25% air void structure.
Aggregate gradation is one of the key elements of a successful
project. The aggregate must be clean and
appropriately graded. 3/8" ‘rounded gravel’ or limestone is
typically used. Cement contents vary but generally
fall in the 500 – 650 lb/yd3 (300-385 kg/m3) range. Water content
is kept as low as possible in order to maintain
Euclid Chemical manufactures and supplies
various admixtures to aid in the production, placement, leveling,
and curing of pervious concrete.
