Admixtures DOV® Super Plast

DOV® SUPERPLAST is naphthalene based Superplasticizer for improved workability and increased early strengths in concrete.

Area of Application

• Ideally suited for concrete placement in areas with congested reinforcement where vibration is cumbersome.
• Highly recommended in ready mix concrete for producing pump able concrete.
• Extremely useful for pre-cast constructions, concrete sleepers, electric posts and pre-stressed concrete constructions.
• Facilitates construction with low water/cement ratio and thereby improves durability of concrete structures.
• Useful for concreting in coastal areas and tidal zones.
• Envelopes the aggregates reducing internal and external friction thereby improving cohesion of concrete.
• Uniform dispersion of ingredients ensures production of a homogenous mix with reduced segregation.
• Improves workability of concrete without air entrainment

Features & Benefits

• Optimization of cement content leading to cost savings.
• Permits significant reduction in water/cement ratio.
• High early strength and increased ultimate strength.
• Envelopes the aggregates reducing internal and external friction thereby improving cohesion of concrete.
• Uniform dispersion of ingredients ensures production of a homogenous mix with reduced segregation.
• Improves workability of concrete without air entrainment.
• Makes early removal of forms possible.
• Reduces permeability and improves durability of concrete.
• Conforms to ASTM C 494 – 98 Type F and BS 5075 Part I

Method of Application

Mixing

Blend cement and aggregates in a concrete mixer as per mix design for about two minutes. Add 75-80% mixing water slowly and blend for about three minutes. Add specified dosage of DOV® SUPERPLAST (@300ml/50Kg cement) to the remaining gauging water and mix thoroughly before adding to concrete mixer and blend further for two minutes. Pour concrete into the mould/ carry out plastering as the case may be. Cure the concrete/ plaster adequately. DOV®SUPERPLAST can be used with all types of Portland cement including blended cement, sulphate resistant cement and white cement.

  Precautions

• Do not add directly to dry mixes.
• Gauge dosage correctly before commencing mixing. Do not tamper with the mix later.
• Maintain water/cement ratio as low as is possible.
• Do not alter the recommended dosage.
• In case of Ready Mix Concrete, if Retarder Superplasticizer has been added in the plant, do not add DOV™ SUPERPLAST further at site.
• Do not premix with other admixtures.
• Do not increase the dosage without consulting Dovchem
