such a way, so that it is about 150 mm – 200 mm above the damp floor.

During
storing cement we have to maintain a space of 300 mm all around between the
exterior walls and the stacks.

While
stacking cement bags more than 8 bags high, the cement bags should be arranged
alternately length-wise and cross-wise, so as to tie the stacks together and
minimize the danger of toppling over.

When
it is required to store cement bas for a long period of time or for during the
monsoon seasons, completely enclose the stack by a water proofing membrane such
as polyethylene.

HOW TO STORE
STEEL ON SITE?
Steels should be stored in such a way, so as
to avoid distortion and to prevent deterioration and corrosion. In order to prevent any compromise in the TMT steel
bars for construction, reinforced bars must be handled and stored with
precaution. Proper handling of the TMT bars is essential for its efficiency.
Handling the TMT Re-bars at construction sites involve different operations
namely – Unloading, Hoisting, Stacking, Cutting, Bending, Fabrication, Welding
etc. Since TMT steel rebar plays a crucial role in maintaining the structural
integrity and durability of the building, it is essential all these operations are
properly maintained at the construction site. Steels of different
classes should be stored separately. Follow the guidelines given below while
storing steel on site.

STORING OF STEEL REINFORCEMENT
·
Whenever the rebars are
ordered, the area where it must be unloaded must be moisture and dust free.
Also at the time of unloading, use timber beds in order to avoid contact with
dirt and water.

·
Covering the steel
rebars with polythene sheets will protect the reinforced bars from moisture.
Alternatively, a covered shed can be used.

Store
bars of different classes, sizes and lengths separately to facilitate issues in
such sizes and lengths so as to minimize wastage in cutting from standard
lengths.

·
Optimize the stacking
height for the reinforced bars. The more the stacking height, the more load
bars will have to endure at the lower layers. The excessive load may damage the
Ribs on the surface of the rebar, which in turn reduces tensile strength.

Paint
the ends of bars of each class in distinct separate colors.

STORING OF AGGREGATE ON SITE
·
Whenever the aggregate
and sand are ordered, the area where it must be unloaded must be moisture, mud
and dust free. Also at the time of unloading, use polythene layer on ground in
order to avoid contact with dirt and water.

·
While
unloading aggregate and sand if such a surface is not available then prepare a
platform of planks or old corrugated iron sheets, or a floor of bricks, or a
thin layer of lean concrete so as to prevent aggregate from contamination with
clay, dust, vegetable and other organic matter.

·
While
unload aggregate and sand we have to maintain sufficient distance between
stacks of fine and coarse aggregates to prevent the material from getting
intermixed.

At
a construction site or unloading area, if possible then construct temporary partition
walls to give each type of aggregate its own compartment.
