DESCRIPTION
CEMSCREED HM (F) is supplied as a ready-to-use,
blend of dry powders which requires only the
site addition of water to produce a free
flowing, non-shrink repair micro concrete. The
materials is based on Portland cements, graded
aggregates, fillers and additives which impart
controlled expansion characteristics in the
plastic state while minimising water demand. The
low water requirement ensures high early
strength and long-term durability, For larger
repairs, the mixed CEMSCREED HM (F) may be
modified by the addition of 12 mm clean, graded,
saturated, surface dry aggregates at site.
SURFACE PREPARATION : The unrestrained surface
of the repair must be kept to a minimum.
Defective concrete surface must be cut back to a
sound base. Smooth surface should be
mechanically roughed. Corroded reinforcement
should be exposed around its full circumference
and remove all loose scale and corrosion
deposits. Apply one coat of SAFECORE R to the
exposed reinforcement. If any discontinuity in
the applied film is noticed, one more coat has
to be applied. The concrete substrates should be
saturated with water. Prior to immediate
placing. Free water should be removed and prime
the substrate using FAIRBOND EP, a slow setting
epoxy bonding aid. FAIRBOND EP shall be applied
on dry substrate.
FORMWORK : Formwork should be leak-proof when
subjected to hydraulic pressure imposed by the
micro concrete will be fabricated and erected
where necessary, provision will be made for air
vents to prevent air entrapment, drainage
outlets for presoaking. Formwork should be
coated with SETRELEASE, mould releasing agent
prior to fixing.
MIXING AND PLACING : Care should be taken to
ensure that CEMSCREED HM (F) is thoroughly
mixed. CEMSCREED HM (F) mix in suitably sized
drum with a torque (400-500 RPM) rotary drill
fitted with a mixing paddle. Where the addition
of graded aggregate has been specified it should
be added after the water and CEMSCREED HM (F)
are properly mixed. PLACING : The mixed material
should be placed immediately. If placed by pump,
standard concrete pumping should be followed.
CURING : Curing should start within 2 hours and
minimum curing time should same as that for
concrete (7 days) as a cementitious material.
Low temperature: In cold conditions down to 15oc,
the use of warm water (up to 30oC)
is advisable to accelerate strength development.
