SUPER PLASTICIZER FOR CONCRETE |
An unmatched the ultimate admixture for cement concrete. Specially developed for delaying hydration of cement with reduced cement water ratio at a given workability by increasing compressive strength at all ages without affecting the long term mechanical properties of cement.
In cement concrete phenomenon of SPC-99 is observed as under :
• Faciliate transportation of readymix concrete (RMC) over long distances even in hot climates without loss of strength.
• Mass concrete and high reinforcement concrete structures where construction joints have to be avoided.
• Cementation of oil wells, ready mix oil well cement
• High quality concrete pours which demand good workability throughout placement in large section.
• Hot weather concreting with long and difficult pours.
• Produces extremely workable, high strength, pumpable water tight dense concrete.
• Produces durable, crack resistance, frost resistance deicing salt resistance concrete.
Test results Conducted on concrete using SPC-99
MIX : Cement (OPC) + Sand = 32%
Crushed Aggregate (5-20 mm) = 68%

Application of SPC-99 :
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 :
• Smooth hot weather concreting
• Smooth hot weather concreting
