BENEFITS
-› Chloride
free - safe in prestressed and reinforced concrete.
-› Produces
exceptionally high early strength.
-› Plasticising
action gives increased workability and/or increased strength.
-› Early
setting improves frost resistance.
-› Suitable
for bricklaying mortar mixes.
-› Particularly
effective in concrete at low temperatures.
USES
To accelerate the setting and early strength
gain of Portland cement concrete and mortar mixes without the introduction of
chloride. Acts as a plasticiser, so gives significant increases in both ultimate
and early strengths. Typical applications include precast concrete, concrete
placed in cold weather, concrete for repairs, mortars for brickwork.
DESCRIPTION
FAIRCRETE NC is a chloride free plasticiser to
accelerate the strength in the concrete which is
ideally useful for cold weather. Gives
additional frost protection by reducing the
water content and accelerating hydration of
cement.
PACKING
FAIRCRETE NC is supplied in 1 ltr., 5 ltr., 10
ltr., 50 ltr., & 100 ltr.
DOSAGE
The recommended dosage range for standard
concrete and mortar mixes with all grades of
Portland cement is 1 to 2 litres per 50 kg
cement. Exact dosage canbe determine by site
trials.
PROPERTIES
Specific gravity : 1.25 at 300C ;
Calcium chloride content : Nill to BS 5075 ; Air
entrainment : Less than 1%.
Compatibility with cements : May be used with
all types of Portland cements. Not suitable for
use with high Alumina cement. Acceleration : The
addition of FAIRCRETE NC to portland cement
concrete mixer accelerates both the setting and
strength gain. The strength improvments are most
significant during the first 18 hours.
Long Term Effects : Accelerated corrosion
testing of steel in concrete has shown that
FAIRCRETE NC does not attect the protection of
steel against corrosion even at four times the
normal does level.
Mixing : FAIRCRETE NC should be stirred well
before use.
Overdosage : An overdose of double the
recommended amount of FAIRCRETE NC will result
in excessive acceleration.
Dispensing : The correct quantity of FAIRCRETE
NC should be measured by means of a recommended
dispenser. The company's technical department
should be consulted regarding suitable equipment
and its installation. FAIRCRETE NC should be
added direct into the mixer. Best results are
obtained when added at the same time as the
mixing water.
Curing : A concrete curing membrane should be
used, or alternative methods such as polythene,
water spray or wet hessian.
Cleaning : Spillages of FAIRCRETE NC can be
removed with water.
STANDARD
FAIRCRETE NC complies with BS 5075 Part 1 and
ASTM C 494 Type C.
SHELF LIFE
Minimum shelf life of 12 months provided the
temperature has not exceeded 20C
to 500C.
HEALTH &
SAFETY
FAIRCRETE NC is toxic. Do not ingest. If
ingested, give an emetic of common salt in water
and seek immediate medical attention. Prolonged
contact with skin should be avoided. Any
splashes should be washed well with water. The
use of rubber gloves and safety glasses is
recommended. Any splashes to eyes should be
flushed immediately with plenty of clean water
and medical treatment sought.
