SikaPlast®-410

Workability enhancing, plasticising admixture

SikaPlast®-410 is a multi-purpose water reducer and plasticizer, utilizing technology unique to the SikaPlast®-400 Series range of products. A range of Ready Mixed concrete plasticisers, specifically designed to produce soft concrete rheology with enhanced workability retention and improved wet concrete cohesion.

Water Reduction: SikaPlast®-410 can be dosed at low to medium quantities to obtain water reduction from 5-16% and will achieve water reduction up to 20% at high dosage rates. Extended Slump Life and Set Control: SikaPlast®-410 has been formulated to provide controlled and predictable extended slump life for periods of 90 to 120 minutes (depending on dosage) allowing good slump retention without significant loss in early strength. The combined high range water reduction and plasticising action of SikaPlast®-410 provides the following benefits in hardened concrete:
  • Higher early compressive strengths for earlier removal of forms and structural use of concrete. 
  • Higher ultimate strengths allow for greater engineering design flexibility and structural economies.
  • Reduced water cement ratios produce more durable, dense concrete with reduced permeability. 
  • Highly effective plasticiser reduces surface defects in concrete elements and improves aesthetics appearance. 
SikaPlast®-410 does not contain formaldehyde or added chlorides and will not initiate or promote the corrosion of steel present in the concrete.

Usage

SikaPlast®-410 may be used in both ready mix and on site batching applications:
  • As a plant added high range water reducer (High dosage range), to provide excellent plasticity, while maintaining slump for ~120 minutes with minimal retardation.
  • As a plant added mid range water reducer (Medium dosage range), for pumped concrete flatwork and applications where superior finishing characteristics are required with low retardation levels.
  • SikaPlast®-410 is suited for use with irregular shaped and graded aggregates, as found with some crushed sands and stone.
SikaPlast®-410 is ideal for use with lean, harsh concrete mixes, and concrete containing, slag or fly ash.

Application

Application Information

Dispensing

Dosage rates will vary according to materials used, ambient conditions and the requirements of a specific project.

Full dosage range:

0.4 – 1.4% by weight of cementitious (400 - 1400 ml/100kg cement)

Typical dosage range:

0.6 - 1.0 % by weight of cementitious (600 - 1000 ml/100kg cement)

DISPENSING

SikaPlast®-410 is added to the gauging water or simultaneously with it poured into the concrete mixer.  For optimum utilisation of the high water reduction, we recommend thorough mixing at a minimal wet mixing time of 60 seconds.

The addition of the remaining gauging water – to fine tune concrete consistency – may only be started after 2/3 of wet mixing time, to avoid surplus water in the concrete.

SikaPlast®-410 can also be added directly to the freshly mixed concrete in the concrete mixer at the end of the batching cycle.

Frozen SikaPlast®-410

Frozen SikaPlast®-410 may be used after it has been slowly thawed at room temperature and intensively mixed. 

Combinations with other admixtures

SikaPlast®-410 is highly effective as single admixture or in combination with many admixtures in the Sika System. 

Field evaluations are needed to determine, based on local materials, the proper dosage of any combination of admixture used. Please contact your local Sika representative for more information and assistance.

Combinations with cement extenders

SikaPlast®-410 is particularly well suited for use with slag and fly ash because of its water reduction capability with superior slump control and early strength development.

 

Application steps

APPLICATION INSTRUCTIONS

The standard rules of good concreting practice concerning production and placing are to be followed.

Fresh concrete must be cured properly and as early as possible.
