Cement concrete blocks are made using about 10% - 12%
cement. Cement, sand, dust, 1”, ½”, ¼” khadi or chhal is mixed to form
cement mortar. The blocks are compacted manually
or mechanically.
Due
to greater demand during masonry work the blocks hardly gets 5-6 days curing.
Generally
28 to 30 blocks of 6 X 8 X 12 are made per bag of cement. Breakage
of even 3 – 4
blocks means a loss of 10% - 12% .
Due
to high silt / mud in sand, block breakages is high and block quality is poor.
In
absence of insufficient curing,
adequate strength is not
developed which may
aggravate seepage in case of walls facing wind & rain.
All
these difficulties can be overcome by using our Block Maker. By using Block
Maker following advantages are available:
1.
Block Maker is
an accelerator
cum plasticizer, it ensures
early high
strength , hence minimizes
breakages.
2.
Block Maker
ensures blocks
are cast
compact and
dense and
imparts water proofing
features.
3.
Addition of
200 ml Block Maker
per bag of cement not only
gives early high strength but also yields
high ultimate strength. Hence
saving in cement up
to 10% - 15% is feasible. 35
– 36 blocks can be cast out of one bag of cement using Block Maker instead of 28–
30 blocks without affecting
physical properties of blocks.
4.
Cost of
addition of Block Maker
is completely offset by
savings in cement,
plus reduced breakages, plus additional 5/6 blocks,
reduce cost per block considerably.
5.
Use of Block
Maker reduces sensitivity of blocks
and mortar to presence
of silt / mud
in sand, hence inspite of high silt / dust,
firm, strong blocks can be
manufactured.
6.
Upto a maximum of 10% fly ash may be used to
impart improved finish
& impermeability
features to the blocks.
METHOD OF USE:
Mix
cement and aggregates as usual, add 200 ml Block Maker in gauging water and add
this to mortar. Cast blocks as usual.
