CERAPLAST 300 is a high-grade superplasticizer based on Naphthalene, highly recommended for increased workability and high early and ultimate strengths of concrete.
Reduction in water-cement ratio
Optimization of cement content - cost savings
Considerably high early Strength
Increased ultimate strength
Improved water tightness
Early removal of form work
High quality concrete of lower permeability and improved durability
Suitable for bottom layer of paver blocks and concrete blocks
Ceraplast 300 disperses cement particles more rapidly in the concrete mix by reducing the surface tension of water and imparting repelling charges to the ions in solution. This makes the concrete highly workable and flowable even at lower water- cement ratios, resulting in increased strength.
Ceraplast 300 facilitates concrete placement especially where
congestion of reinforcement occurs and vibration is not easy.
Ceraplast 300 is recommended for producing pumpable concrete and for ready mixed concrete.
Ceraplast 300 is highly useful for pre-cast concrete constructions and for concrete sleepers, electric posts and for pre-stressed concrete constructions.
Ceraplast 300 increases durability of concrete structures by facilitating construction with the reduced water- cement ratio and hence it is ideal for marine / coastal structures, especially in tidal zones.
Ceraplast 300 when incorporated into the concrete improves the workability of the concrete without air entrainment due to its excellent dispersion characteristics and also imparts coating to the aggregates. Due to this, internal and external friction is reduced and cohesion of concrete is considerably improved. The uniform dispersion ensures better homogeneity of the mix and minimizes the risk of segregation during placement.
Method Of Use:
Ceraplast 300 is directly added into the mix at the same time as the gauging water. Reduce water dosages for required consistency.
Ceraplast 300 can be used with all types of Portland cement including blended cements and Sulphate resistant cement. Ceraplast 300 should not be pre-mixed with other admixtures. If other admixtures are to be used on concrete containing Ceraplast 300 they have to be added separately. Ceraplast 300 will not have any deleterious effect on reinforcing/ pre-stressing elements.

Reduced water-cement ratio reduces permeability and improves durability. Improved workability facilitates easy placing and good compaction, resulting in production of impermeable concrete.
Substantial reduction in the water content i.e. 12% - 25% can result in high early compressive strength for a constant slump. The ultimate compressive strength can be enhanced by up to 25% by proper mix design with Ceraplast 300.
Conforms to ASTM C 494 - 98 Type F and IS 9103-1999
0.3% TO 1.5% Ceraplast 300 by weight of cement. Maximum dosage may have to be increased to as high as 3% of cement weight where exceptional early strength is required. Suitable modifications in the mix design is required in such cases.
Practically unlimited in sealed original containers. However, it is advisable to use within 12 months from the date of manufacturing
