KALMATRON® KCKALMATRON̉KC
- ADMIXTURE TO CEMENT
¢ INTRODUCTION ·
Even
the final product of the cement clinker has a lot of foreign
inclusions in the frame of the cement structure. During the
hydration of Portland cement, approximately 30% of the hydration
products form calcium hydroxide, which is also known as a free lime.
This has no cementitious value by itself. It is soluble in water and
causes powerful conduction of liquids through the concrete body.
Therefore, up to 30% of cement in a concrete mix becomes not only
useless, but also harmful for concrete durability. ·
For
a cement particle that measures 50 mm
across, the depth of hydration is 4 mm
at 28 days and 8 mm
after a year. Full hydration has only been obtained by grinding
cement in water continuously for five days. The standard average
across measurement of a cement particle is over 90 mm. · KALMATRON̉ KC was developed as an admixture to cement to increase hydration by molecular decay of unstable relations between foreign inclusions with cement particles. After that, hydration is an entirely completed reaction with a higher performance of concrete rheology that obtains many features of High Performance Cements and High Alumina Cements. The lower the grades of cement powder, the higher the effectiveness of KC. ¢
DESCRIPTION of KC KC
is a gray dry powder with a light specific smell. This non-organic
cementitious modifier works as a Cement’s Type Upgrading Admixture
to enhance the final features of the resulting concrete mix. ¢
APPLICATION ·
Add
KC with a 1% ratio to the cement weight (10 Kg of KC per 1000 Kg of
cement). ·
Mix
by using advanced technology for a homogeneous mix. · Apply the final mix of the cement containing KC using the standard technology. ¢
USES ·
Enhancing
of the low-active and polluted cements type I;II to get the highest
modifications. ·
Use
KC-cement for concrete used in civil, hydro-technical and
fortification structures. · Early strengthening and waterproofing of the ready mixed concrete and mortar. ¢ BENEFITS
FOR CONCRETE APPLICATION ·
Reduces
dosage of water in the Water-Cement ratio by 10 to 20%, and more. ·
Reduces
the amount of Cement needed by at least 15 to 25% and still obtain
the conventional concrete
mix. ·
Increases
compressive strength by 25% and more. ·
Increases
impermeability 2 to 4 times and reduces exothermic heat up to two
times. ·
Increases
Density, Reduces Shrinkage & Accelerates Early Strength. ·
Improves
Resistance of Sulfate, Acid, and Petroleum Corrosions. ·
Increases
Freeze/Thaw durability. · Increases Yield of the ready mix concrete by 3% to 6%.
¢ TRANSFORMATION
OF PORTLAND CEMENT BY USING KC ADMIXTURE As it is known, the production or enhancement of the high quality Portland cements is expensive because of fine grinding, long term burning in kiln, cooling, etc. Application of KC is as simple as mixing with the cement during the last stage of the standard technology. Selective tests of pre-admixed KC with the worst cement in the plant will result in a highly modified type of cement in accordance with ASTM classifications. ¢ VARIETY
OF KC APPLICATION
Depending
on the initial cement quality, the results of selective tests in a
laboratory may vary. The lower the grade of local cement, the better KC will perform. Type I Portland Cement + KC =
Before testing, please inform us about the mineralogical content of the original cement. This is necessary to get a successful selection of the needed dosage and stable quality of application.
