(1) Higher Strength
Clinker is the basic raw material of cement. When blast furnace slag is used as a part of
cementitious material in a concrete mix, it reacts with water and Ca(OH)2 to form more Calcium
Silicate Hydrate (CSH) gel. CSH is the glue that provides strength and holds concrete together. The
additional CSH densifies the concrete matrix and enhances strength. Usage of 72-79% clinker in Akij
Cement and its additional CSH gel of Blast Furnace Slag, increases 15% more strength in 91 days
than other cements. The result of test of Change in long-age strength of various kinds of cement by
technical Committee of Japan Cement Association is shown below:

(2) Sulfate Resistant
Sulfate attack is a common form of concrete deterioration. It occurs when concrete comes in
contact with water containing sulfates (SO4). Sulfates can be found in some soils.
According to the ASTM C1012 test , the concrete gain higher sulfate resistance ability [ only 0.05% in
6 month duration] when 18-25% blast furnace slag is mixed with clinker. Because Blast furnace slag
cement does not contain C3A and produced more CSH [Calcium Silicate Hydrate] decreases the
production of Ca(OH)2 during its hydration process, which protect Ettringite compound formation in
concrete and thus there is no chances of tensile stress and sulfate attack in salty environment
[Chemical reaction: SO4 + Ca (OH)2 = Ettringite =Concrete Crack]

(3) Anti-Crack
It is most difficult to control inner temperature of mass concrete between surface temperatures
during its hydration process. These unbalanced temperatures may create “Thermal cracks”.
The blast furnace slag cement can mitigates this high inner temperature by producing more CSH gel
and reduce the possibility of thermal cracks. The result of adiabatic temperature rise test shows the
following:

Reference: Slag Cement Association Website,
http://verio2.slagcement.org/Publications/pdf/no5%20Producing%20and%20Placing%20Slag%20Cement%20Concrete.pdf
(4) Corrosion Resistant
In hydration process, blast furnace slag cement reacts with water and calcium hydroxide Ca(OH) 2 to
form additional CSH gel. CSH is the glue that provides strength and holds concrete together with
reinforcement [Rod] and resulting in lower permeability. Lower permeability reduces chloride-ion
and other air access to the RCC and thus reduces the corrosion of inner structure.
According to the ASTM C1202 of Rapid Chloride Permeability Test, the corrosion of reinforcing bar
(rod) is shown below:
Fig: Corrosion of reinforcing bar in marine environment

http://verio2.slagcement.org/Publications/pdf/no5%20Producing%20and%20Placing%20Slag%20Cement%20Concrete.pdf
(5) Better Workability
Slag cement improves the workability of concrete due to its fine grind and glassy structure.
Enhanced workability benefits placing, compaction and finishing of the concrete. The resulting
concrete elements may have fewer surface voids and improved consolidation. Slag cement has also
been used effectively in the design of self-consolidating concrete mixtures. By improving the
durability of the concrete, the service life of the concrete element increased.

(6) Improved Durability
Slag cement mixtures produce more durable precast/pre-stressed concrete. Slag cement can
significantly improve the durability of concrete in following ways and consequently extends the life
of concrete structures.
 Reduces permeability: Lowered permeability inhibits the ingress of chloride ions that can
contribute to corrosion of reinforcing steel. Additionally, keeping water out of the concrete
matrix significantly decreases susceptibility to many durability problems, such as sulfate
attack and Alkali-Silica-Reaction (ASR).
 Chemically: resistance to aggressive sulfate solutions and mitigates deleterious reactions
between cement alkalis and reactive silica in aggregates.
 Physically: reduces the heat of hydration, thus lessening thermal cracking and improves
ultimate compressive and flexural strength. During the life of the structure, these strengths
normally increase well beyond the 28-day specified strength, significantly more than plain
port land cement concrete.
A life cycle cost computer model (ACI Life 365)1, based on the initial concrete cost and future repair
costs. An example is shown in the below figure:

http://verio2.slagcement.org/Publications/pdf/no5%20Producing%20and%20Placing%20Slag%20Cement%20Concrete.pdf
(7) Whitish Shade
Slag cement is lighter in color than Portland cement. Elements made with slag cement will therefore
have a lighter finished color. The higher the percentage of slag cement used, the lighter the color
will be. This provides greater visibility of the elements and potentially improved safety. Slag cement
will provide lighter concrete with higher reflectivity than plain Portland cement concrete. This type
of cement is very much effective for fair-face structure.
