CERAPLAST 400 is a high performance, low dosage superplasticizer based on Melamine Formaldehyde Sulphonate (MFS). Highly recommended for increased early strength of concrete, which is a must for pre-cast and pre-stressed concrete industries.

Advantages:

  • Substantial reduction in water-cement ratio
  • Considerable high early Strength
  • Increased 28 day strength
  • Improved water tightness
  • Early removal of formwork
  • High quality concrete of lower permeability and improved durability
  • Improves dispersion and sheen of pigment

Function:
  • Ceraplast 400 disperses cement particles more rapidly in the concrete mix by reducing the surface tension of water and imparting repelling charges to the ions in the solution. This makes the concrete highly workable and flowable even at lower water-cement ratio, resulting in increased strength.

Uses:
  • Ceraplast 400 is very advantageous for pre-cast concrete constructions and for concrete sleepers, electric posts and for pre-stressed concrete constructions.
  • Ceraplast 400 is a proven performance enhancer for paver blocks and decorative cement tiles by early removal of form work and improving dispersion and sheen of pigment.
  • Ceraplast 400 facilitates concrete placement especially werethere is congestion of reinforcement and vibration is not easy.
  • Ceraplast 400 is ideal for pre-stressed bridge girders of large spans
  • Ceraplast 400 increases durability of concrete structures, as it is possible to produce high strength concrete with low water cement ratio. Hence it is ideal for marine / coastal structures, especially in tidal zones.
  • Ceraplast 400 when incorporated into the concrete mix, it improves its workability without air entrainment due to its excellent dispersion characteristics. The uniform dispersion ensures better homogeneity of the mix and minimizes the risk of segregation during placement.

Method Of Use:
  • Ceraplast 400 is directly added into the mix at the same time as the gauging water. Reduce water dosages for required consistency.

Compatibility:
  • Ceraplast 400 can be used with all types of Portland cement including blended cements, sulphate resistant cement and white
  • Cement. Ceraplast 400 should not be pre-mixed with other admixtures.
  • Ceraplast 400 can be used with all types of Portland cement including blended cements, sulphate resistant cement and white
  • Cement. Ceraplast 400 should not be pre-mixed with other admixtures.

Permeability:
  • Reduced water-cement ratio reduces permeability and improves durability. Improved workability facilitates easy placing and good compaction, resulting in production of impermeable concrete.

Compressive Strength:
  • Substantial reduction in the water content i.e. 20% - 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 400.

Recommended Dosage:
  • 0.3% to 1.5% Ceraplast 400 by weight of cement. Maximum dosage may have to be increased to as high as 2% of cement weight where exceptionally high strength is required. Suitable modifications in the mix design is required in such cases.

Shelf Life:
  • Practically unlimited in sealed original containers. However, it is advisable to use within 12 months from the date of manufacturing

    Function:
    • Ceraplast 300 - RS(G) is a high performance new generation superplasticizer cum retarding admixture which lowers the surface tension of water and makes cement particles hydrophilic, resulting in excellent dispersion as well as controls the setting of concrete, depending on dosage. This increases the workability of concrete drastically and also facilitates excellent retention of workability. The workability offered at a lower water-cement ratio eliminates chances of bleeding and increased workability retention allows increased travel time.

    Uses:
    • Ceraplast 300 - RS (G) has excellent slump retention properties (based on dosage) and hence is a recommended admixture when concrete is to be transported over long distances.
    • Ceraplast 300 - RS (G) provides concrete of flowing consistency and facilitates concrete placement through pumping or tremie.
    • Ceraplast 300 - RS (G) permits proper placement and finishing, overcoming the damaging and accelerating affects of high temperatures, because of its retarding effect.
    • Ceraplast 300 - RS (G) because of its capability to impart flowing consistency to concrete can be used with advantage where congestion of reinforcement occurs and vibration is difficult.
    • Ceraplast 300 - RS (G) in designed proportion controls the setting of large structural units to keep concrete workable throughout the placing period. This eliminates cold joints and discontinuities.
    • Ceraplast 300 - RS (G) helps in the production of dense and impermeable concrete, thus making it an ideal choice for coastal structures.

    Method Of Use:
    • Ceraplast 300 - RS (G) can be directly added into the mix at the same time as the gauging water. Reduce water dosages for required consistency.

    Compatability:
    • Ceraplast 300 - RS (G) can be used with all types of Portland cements including blended cement, and sulphate resisting cement. It is also compatible with mineral admixtures like fly ash, slag and silica fume.
    • Ceraplast 300 - RS (G) should not be pre-mixed with other admixtures. If other admixtures are to be used on concrete containing Ceraplast 300 - RS they have to be added separately.
    • Ceraplast 300 - RS (G) has no adverse effects on reinforcing elements.

    Permeability:
    • Reduced water- cement ratio reduces capillary porosity and improves water tightness. Improved workability facilitates easy placing and good compaction, resulting in production of dense, impermeable concrete.

    Compressive Strength:
    • Substantial reduction in the water content, i.e. 20% to 25% can result in high early compressive strength for a constant slump.
    • The ultimate compressive strength can be enhanced by up to 25 % by using Ceraplast 300 - RS (G) with a properly designed concrete mix.

    CERA MICROSEAL is a specially formulated co-polymer based integral waterproofing compound for cement mortar and concrete, which will reduce the water demand and improve impermeability.

    Advantages:
    • Reduces permeability and water absorption of concrete and mortar without reduction in strength
    • Reduces water requirement of concrete and mortar mixes for required workability
    • Improves bond strength of mortar to porous substrates like brick / old concrete
    • Reduces shrinkage cracks in joints and plaster
    • Does not adversely affect the setting time of cement
    • Excellent water resistance

    Function:
    • Cera Microseal is a superior cement modifier, modified with selected co-polymers. The polymers form an interpenetrating film around the cement hydration products, which increases the water retention and bonding characteristics of mortar and concrete. The polymer particles also impart a ball-bearing effect to the mortar/concrete, aiding in increased workability.
    • Cera Microseal being a free flowing polymer penetrates into the cavities of the concrete and acts as a barrier to prevent the leakage of water. It coats the internal pores and channels of cementitious mixes, thus producing a dense and impermeable material.

    Uses:
    • Cera Microseal can be used wherever mass concrete is specified for below grade constructions such as basement walls, floor, foundation and swimming pools and grade structures like retaining walls,storage tanks, etc where normal hydrostatic pressure exist.
    • Cera Microseal, when incorporated with cement mortar gives tighter joints in bricks, stone and all types of masonry construction.
    • Cera Microseal reduces the permeability of Portland cement mortar mixes, making it an ideal choice for screed mortars.
