Features / Advantages

• It controls the rate of setting of concrete and mortars.
• It improves workability and easier handling.
• It retains the workability upto three hours.
• It reduces segregation and bleeding.
• It can be used even for micro silica, fly ash and slag cement concrete
• It improves finished appearances of the hardened concrete.
• It reduces shrinkage and permeability of hardened concrete.
• It increases strength of the concrete and mortar.
• It reduces cracking.
• It eliminates formation of cold joints between subsequent pours in mass or structural concrete.
• It entrains minimal air without affecting strength parameters.
• It is based on Sulphonated Naphthalene formaldehyde polymer.
• It does not contain chlorides or nitrates.

Directions For Use:

Dosage:

To get the required workability retention of concrete mixes depends upon the ambient temperature and other factors. Hence trial mixes should therefore be performed. The normal dose is 0.05 to 0.75 ltr. per 50 kgs. of cement. A dosage upto 1 litre per 50 kgs. of cement can be used when micro silica, fly ash, slag cement etc, are present in the mix. Masterplast SPL-9 should be added to the wet mix or mixing (gauging) water. It should not be added to dry cement. For addition of Masterplast SPL-9 a dispenser or exact measuring container is recommended. Stir well before use.

Cleaning Of Tools & Equipments
Tools and equipments can be cleaned with Water.

Storage And Shelf Life

• Store the material at a cool & dry place (preferably at 30°C Temp. or at room temperature).
• Shelf life is two years.
• It will freeze at (thawing) temperatures but can be reconstituted by stirring.

Packing
5 Litre, 20 Litre, 200 Litre, or as per requirement.


Precautions

• Do not mix it with dry cement
• Add to mixing (gauging) water or directly to the mix.
• Stir well before use.
