SPC-99TM (Super plasticizer for cement)
High performance super plasticizer for cement base mortar
SPC-99 TM is a modified a poly carboxylic ether based high range water reducer specially developed plasticizer of cementitious construction material.
SPC-99 Super plasticizer is a powerful dispersant, capable of producing very mobile flowing, pumpable concrete, normal flow and slump characteristic can be maintained with water reduced mix, resulting the added benefit of increased final strength.
SPC-99 is used to produce concrete having unchanged strength development, yet vastly improved workability when compared to a control mix containing no super plasticizer.
Dosage Level: To produce placeable concrete containing only the minimum water of hydration or to produce full flowing self-leveling concrete will as a general require the addition of 0.6% to 1.0% SPC-99, the weight of dry cement in the mix.
The actual amount required to achieve a particular result will vary with the type of cement the size, shape and grading of aggregate and the total mix design.
Thus for a particular specification for the concrete the additive level to be used can only be established by trials using the cement, aggregate and mix specified.
Over dosing of SPC-99 can result in some set retardation. However, the ultimate strength and other properties of the concrete will not be impaired.
SPC-99TM: Establish stable slump value with water reduction up to 40%. Ph – 6-8 radish grey. Compatibility – Portland cement, micro silica, PFA & slag.
Addition of SPC-99: Once the liquid had been added to the concrete the flowing state is reached immediately and the material is ready for placing. It should be used without delay. It will hold high workability between 30-120 minutes depending on humidity and ambient temperature too.
The system developed represents numerous trials and is intended only for guidance in the formulation of trial mixes. Field trial for each mix should always be made.

Field of Applicable:
Road, Bridges and Rails, Harbors, Fast-Setting, Floor Screeds. Non Shrink Grouts, Injection mortars, underground structures.
Area of Application
Most suitable for construction of high ways, roadways, aprons & hard standings, very useful in dams, reservoirs, power station, under ground tanks etc. Ideal for ready mix plants, pre-cast concrete, prestressed concrete, hot weather concrete closely space & areas, large bay areas, floor slabs, bridge decks and other areas when high slump property is required.
HOW to Use
1) As per the job condition in general add 100ml. to 500ml. of
SPC-99 with required guaging water for every 50kg. cement in the concrete/mortar mix. Cure as per the constraction norms.
2) Effect of SPC-99 may vary with cement type, grading of sand,
size & shape of aggregates, temperature, other job conditions etc. Therefore to faciliate addition and to prevent over dosing, it is advised to determine on trial mixes the actual dosage.
