Introduction: -
Cement concrete tiles and paving blocks are precast solid roducts made out of cement concrete. The product is made in various izes and shapes viz. rectangular, square and round blocks of different
imensions with designs for interlocking of adjacent tiles blocks. The raw materials required for manufacture of the product are portland cement and aggregates which are available locally in every part of the country.
MARKET POTENTIAL
Cement concrete tiles and paving blocks find applications in avements, footpaths, gardens, passenger waiting
sheds, bus-stops, industry and other
public places. The product is commonly
used in urban areas for the above
applications. Hence, the unit may be set
up in urban and semi-urban areas, near
the market.
A lot of face-lift is being given to
roads, footpaths along the roadside.
Concrete paving blocks are ideal
materials on the footpaths for easy
laying, better look and finish. Whereas
the tiles find extensive use outside the
large building and houses, lots of these
materials are also used in flooring in the
open areas of public offices and
commercial buildings and residential
apartments.
BASIS AND PRESUMPTIONS
Efficiency: It is envisaged that the unit
will run on one shift a day for 25 days in
a month or 300 days in a year. 75
percent efficiency of machinery and
manpower is considered.
Time Period: Full capacity utilization
is expected to be achieved within 12
months of commencement of
commercial production.
Labour Wages: Minimum applicable
wages are considered.
Interest Rate: An interest rate of 14%
per annum on the total capital
investment has been considered.
Margin Money: Promoter is expected
to bring in 25% of the total capital
investment.
Pay Back Period: The project will have
a payback period of about 3-4 years.
Land and Construction Cost: Land
cost is considered at Rs. 500 per square
meter, and Construction cost for office
and stores at Rs. 2000 per square meter,
and work shed at Rs. 1500 per square
meter.
TECHNICAL ASPECTS
Process of Manufacture
Cement concrete is a mixture of
portland cement, aggregates (sand and
stone chips) and water. Aggregates
passing through 4.7 mm IS sieve are
known as fine aggregates and the
aggregates retained on this sieve are
coarse aggregates.
The process of manufacture of
cement concrete paving blocks involves
the following steps:
a) Proportioning
b) Mixing
c) Compacting
d) Curing
e) Drying
A concrete mix of 1:2:4 (cement:
sand: stone chips) by volume may be
used for cement concrete paving blocks
with water to cement ratio of 0.62. The
concrete mix should not be richer than
1:6 by volume of cement to combined
aggregates before mixing. Fineness
modules of combined aggregates should
be in the range of 3.6 to 4.0.
All the raw materials are placed in a
concrete mixer and the mixer is rotated
for 15 minutes. The prepared mix is
discharged from the mixer and
consumed in the next 30 minutes.
Vibrating table may be used for
compacting the concrete mix in the
moulds of desired sizes and shapes.
After compacting the blocks are
demoulded and kept for 24 hours in a
shelter away from direct sun and winds.
The blocks thus hardened are cured
with water to permit complete
