Features / Advantages
- Due to water reduction, it increases
not only early and ultimate compressive
strength but also the strength of
concrete at all ages.
- It retains the workability of
concrete for about two hours.
- It gives retardation properties
for 4 to 6 hours which helps to
avoid cold joints in concrete. It
reduces segregation in the concrete.
- It improves finished appearance
of the concrete by minimising honeycombed
surface.
- It allows lowering of cement
contents without affecting the normal
strengths of the concrete.
- Non-foaming .& non-toxic.
- It does not contain Chlorides.
- It does not corrode the reinforcements.
- It is based on modified Sulphonated
Naphthalene Polymers
Usage
- Ready mix concrete
- Precast concrete
- Prestressed concrete
- Closely spaced areas, large bay
areas, floor slabs, roof decks &
other structures etc. Mainly used
in situation where slump retention
property is required upto 3 hrs.

Direction for use
DOSAGE:
Dose of 0.15 to 0.75 Litres. per 50
Kgs. of cement is usually sufficient
to produce self compacting and flowing
concrete. Optimum dose is best determined
by trial concrete mixes, otherwise
normal dose of 400 cc per 50 Kg. of
cement is recommended.
Add MASTERPLAST SPL-5 to the mixing
(guaging) water. Stir well the material
before use.
CLEANING OF TOOLS & EQUIPMENTS
Tools and equipments can be cleaned
with water.
STORAGE AND SHELF LIFE
Store the material at a cool and dry
place (25°C).
Shelf life is two years.
PACKING
5 Litre, 20 Litre., 200 Litre or as
per customers requirement for bulk
quantities.
PRECAUTIONS
Do not mix with dry cement. Add to
mixing (gauging) water or directly
to the wet mix. Stir well before use.
