Sika® Plastiment®-45

Sika® Plastiment®-45

WR - Water Reducer

Sika® Plastiment®-45 is a water reducing concrete admixture based on modified polycarboxylates. It improves dispersion of the cementitious materials, resulting in increased workability and/or water reduction.

  • Improved dispersion of cementitious materials.
  • Reduction in the energy required for effective mixing.
  • Higher slump can be achieved without further addition of water, or higher strength can be achieved at the same slump.
  • Fresh concrete is easier to pump, place and compact.
  • Lower water/cement ratios are possible, improving concrete strength and durability.
Sika® Plastiment®-45 is manufactured from selected polycarboxylates  which reduce the detrimental effects caused by variations in concrete raw materials.

Usage

Sika® Plastiment®-45 can be used to achieve increased workability without loss of strength or to increase strength without loss of workability. It can be used for most concrete applications, including pumped, prestressed and structural concrete. Increasing doses of Sika® Plastiment®-45 may result in longer setting times.

Application

Application Information

Dispensing

Sika® Plastiment®-45 is added with the initial batching water. Never add to a dry mix.

Compatibility

Sika® Plastiment®-45 can be used in conjunction with all the Sika Concrete admixtures, except Sikament ® NN.

All admixtures must be added separetely.
Consumption

Recommended dosage

Recommended dosage is 350 ml± 100 ml per 100 kg of total cementitious material. This dosage can be increased to 600 ml per 100 kg of total cementitious material to improve water reduction and extend setting time. Optimum dosage should be determined by site trials with the particular concrete mix design and materials.
