SikaPlast®-70

Mid Range Water Reducer - MWR

SikaPlast®-70 is a water reducer specifically formulated for use with harsh manufactured sands or poorly-graded natural sand. SikaPlast®-70 improves the finishability, pumping and slump keeping properties of the fresh concrete.

Use of SikaPlast®-70 in concrete improves the following properties: 
  • Reduces water, improving concrete durability.
  • Facilitates an increase in manufactured sand or poor quality natural sand.
  • Increased Ultimate Strength Performance.
  • Improved plastic concrete properties.
  • Ease of placing or pumping.

Usage

SikaPlast®-70 is suitable to produce high performance concrete with poor quality sands. The following types of concrete can use SikaPlast®-70:
  • Mixes containing harsh aggregates and high percentage of manufactured sand
  • Reinforced, precast, prestressed, lightweight, normal weight or pumped concrete.
  • Concrete, where reduced water contents and ease of placing and working with tools is needed.
 

Advantages

Application Information

Dispensing

Add SikaPlast®-70 to the initial batching water. For best result, we recommend thorough mixing of wet concrete at 60 seconds per cubic metre of concrete.

Add the remaining gauging water progressively after at least 2/3 wet mixing time to achieve the desired consistency.

Do not add to a dry mix.

Compatibility

SikaPlast®-70 can be use in conjunction with most of the Sika Concrete admixture, with the exclusion of Sikament NN.

Consumption

Recommended dosage

Typical dosage for general concrete production is between 300-600mls per 100kg of total cementitious material. Optimum dosage depends on site condition, job conditions, mix ingredients and desired plastic and hardened properties. Laboratory and field trials are essential in determining the optimum dosage. SikaPlast®-70 can be used at higher doses to achieve a large water cut and increased set times.
