Remarks on using Kating Thong Brand cement and
clinker
Remark on using Kating Thong Brand Cement
Kating Thong Cement have the high
early strength, reasonable setting time, stable
quality, good adaptability with additives, and so
on. During construction, following items need to be
paid attention to:
-
Pay attention to store, and avoid
moisture.
During transportation and store it is requested
to take necessary measures to avoid seep in the
hold of truck, to put waterproof cover in time;
Cement should be stored in the dry place in
order to avoid humidity into big lump; During
using, we must follow the principle of coming
first, using first, moreover, it is not
appropriated to store too long time, avoid
moisture, which will cause quality decrease; In
addition, cement is definitely not allowed to
put together with sugar, fertilizer, and so on
which will caused bad reaction on quality.
-
Cannot mix different type cement
together
As different type, different grade cement have
difference in quality, specification, it is
requested to separately store, separately use.
The various type and grade cement of different
producers should not be used together mixing;
meanwhile, the same type and grade cement of
different producers cannot be used together.
-
3. To select certain type and
grade cement reasonably
It is requested to select certain type cement
reasonably as per the request of construction
part and concrete strength grade, to avoid the
status, like high grade cement make low grade
concrete, or low grade cement make high grade
concrete, which will cause bad workability and
high slump loss, and lose in cost.
-
Stick to pre-testing of concrete
During using Kating Thong cement, as different
request on building structure, and part as well,
it is requested to stick to pretesting of
concrete, to find out the ratio; In case use new
additives or change additive quantity, should
make pretesting of concrete, try best to select
good adaptability additives; In case some change
from Kating Thong specification items, we will
inform you to make pretesting of concrete, in
order to make sure concrete quality steady.
-
To pay attention to constructing
in order and protect
Should strictly make control in adding the sand,
gravel, water, and other materials, water should
not with organic compound, sand should with low
muddy, sand with high sulfate and alkali cannot
be used; the design of mix ration of concrete
should be as per the constructing design; keep
uniformity when construction mixing,w/c
ratio should be low, pound should be within
measure, no paste spilling, moulding should be
continued,to
avoid concrete strength decline induced by
cement unevenly distributing, eduction, bleeding
and others.
Under high or low air temperature
should control the temperature of admixture to avoid
the rapid or slow setting time for concrete. After
loss the plastic moulding concrete should be water
and covered in time and keep wetness, to avoid
concrete craze induced by to excessively dryness,
meantime please note that no earlier or more for
watering to avoid bad surface blending low strength,
sand and peel appearing.
Remark on using Kating Thong Brand Clinker
|
Kating Thong clinker has the
speciality of high early strength; high silicate
mineral, stable quality and low hydration heat,
meantime Kating Thong clinker possess the ability of
producing different types of clinker. To use Kating
Thong clinker better please take note of the
proceedings as follows:
-
To avoid moisture
During the transportation, store of the clinker,
should seriously pay attention to the solutions
of water proof; should transported with cover in
rainy days; not allow to store openly in order
to avoid moisture and low strength.
-
Using after test; coming first,
using first
Even Kating Thong brand clinker
has stable quality, for the sake of avoid
moisture and mix with different producers
clinker which do impact on quality, it is
requested to stick to the principle of using
after test; To avoid strength decrease induced
by too long time store and humidity please
insist on the rule of first coming first
using. To fully exert the quality advantage of
Kating Thong clinker we suggest that Kating
Thong clinker should not be mixed with other
clinker, especially clinker from vertical kiln.
-
Request on testing
It is requested to make clinker
testing according to China national standard,
and cement industrial standard, like standard
testing mill grading charts, the content of
gypsum, blains control, curing temperature,
humidity and timing, criterion of compressive
test, which make sure exact clinker strength
test so that to guide cement produce and fully
exert the quality advantage of Kating Thong
clinker.
-
To carry out specility testing,
work out the best mix ratio
According to request of various
type cement and its strength grade, it is
important to select the appropriate additive and
gypsum, request us to carry out specility
testing, work out the best mix ratio, to make
full use of clinker quality, lower the cement
production cost.
