Concrete Admixtures

1.PLASTICISERS

CERAPLAST 100:

2. SUPERPLASTICISERS:

CERAPLAST 300:

High range water reducing admixture

• Large reduction in water-cement ratio, high early strength, early removal of formwork
• 
  High quality concrete of lower permeability and improved durability

Ideal for producing pumpable concrete, placing concrete in areas of congested reinforcement, marine / coastal structures, especially in tidal zones Conforms to IS 9103 – 1999 and ASTM C 494 Type F

CERAPLAST 400:

Melamine based super plasticiser for precast concrete application

• Substantial reduction in water – cement ratio
• 
  Increased 28 day strength
• 
  Easy and very early removal of formwork

Very advantageous for pre-cast concrete construction and for pre-stressed large span bridge girders Conforms to IS 9103 – 1999 .

CERAPLAST BS:

Water reducer for concrete blocks

• Produces cohesive and non-segregating concrete
• 
  Faster strength development

Ideally suitable for concrete where faster setting characteristics, enhanced surface appearance and accelerated strength development are desired Complies with IS 9103 – 1999 specifications

3. RETARDERS:

CERA RETARDER:

Controlled set retarding admixture

• Retards setting of concrete during delays between mixing and pouring, prevents cold
     joints
  
• 
  Facilitates workability during high ambient temperature

Very ideal for use when concrete is to be transported over long distances, useful for ready mixed concrete industries Satisfies the stipulations of IS 9103 – 1999 and ASTM C 494 Type B and D

4. RETARDING SUPERPLASTICISERS:

CERAPLAST 300 – RS:

High range retarding superplasticiser for flowing concrete

• Excellent workability at low dosages
• 
  Retards setting time
• 
  Increased strength without increase in cement
• 
  Excellent admixture for ready mixed concrete

Increased workability retention, ideally suited when long hauls are involved Conforms to IS 9103 – 1999 and ASTM C 494 Type G

CERAPLAST 300 – M:

High performance superplasticiser cum retarders

• Compatible with mineral admixtures like slag, reduces heat of hydration even with very
     high early strength cements
• 
  High early strength, increased ultimate strength

Recommended for concrete placement where congestion of reinforcement occurs and vibration is difficult, ideally suited for coastal/marine applications because of improved impermeability Conforms to IS 9103 – 1999 and ASTM C 494 Type G

CERAPLAST 300 – SRV:

Special superplasticiser cum retarders

• Pumpable concrete, longer workability retention
• 
  High strength concrete at reduced water content

Desirable for ready mixed concrete industries where haulage time is more. Quick strength gain and dense, durable concrete are added features Conforms to ASTM C – 494 Type G

CERAPLAST 300 – SR1:

High-grade superplasticising retarders

• Very high workability enhancer
• 
  Low dosage admixture
• 
  Speeds up construction, increases workability and cohesion. Aids in pumping by reducing    the surface tension of water. No chances of bleeding and segregation Conforms to
     IS 9103 : 1999 and ASTM C – 494 Type G
  
  

5. MORTAR PLASTICISER:

CERAPLAST LMP:

Liquid mortar plasticisers No mortar stiffening, segregation or bleeding Less prone to drying shrinkage cracks, increased adhesion, cost effective Accelerates plastering and masonry works, improves the quality of mortar, protects the mortar against bleeding and during shrinkage

6. INTEGRAL WATERPROOFERS:

Conforms to IS 2645 – 1975, reaffirmed to 1992

CERAPROOF IWP – POWDER:

Waterproofing admixture for mortar and concrete

• Improves workability, produces dense and homogeneous concrete, prevents corrosion of    steel by reducing capillaries
• 
  Reduces water absorption of concrete and mortar without causing strength reduction
  
• 
  Used to produce impermeable concrete for water retaining structures, terraces,
     basements,tunnels, piles, plastering applications
  
  

CERAPROOF IWP – LIQUID:

Liquid integral water proofing compound for cement mortar and concrete

• Instant dispersion
  
  
• improved workability
  
  Reduces permeability

Highly recommended for water retaining structures, terraces, basements, tunnels, piles, external and internal plastering of underground structures, tanks, masonry, screed etc.

7. POLYMER CEMENT MODIFIER:

CERA MICROSEAL:

High performance co-polymer based cement modifier

• Reduces shrinkage cracks, permeability and water absorption
• 
  Improves bond strength of mortar to porous substrates like brick/old concrete
  

Used wherever mass concrete is specified for below grade construction such as basement, walls, floors, foundations, swimming pools, retaining walls, storage tanks etc.

8. SET ACCELERATING AND GUNITING AID:

CERA GUNITE RAPID SET:

Powder set accelerating and waterproofing shot Crete admixture

• Reduces rebound losses, reducing the cost of guniting, accelerates strength gain
  
• 
  Does not corrode the reinforcement
  

Highly made use of to seal water seepages in drainage galleries, shafts and tunnels for sprayed concrete and ShotCreting operations even at low temperatures
