Sika® Plastiment® PZ 3089

(former MPozzolith 3089)

High performance retarding plasticiser for concrete

Sika® Plastiment® PZ 3089 is a high-performance plasticising retarder, beneficial in maintaining workability especially in high ambient temperatures. Suitable for use in hot and tropical climatic conditions.

  • Reduces segregation and bleeding
  • Improves cohesion, workability and compactability in concrete using poorly graded/shaped fine aggregates.
  • Reduces placing problems in hot weather by improved workability and workability retention in conjunction with extended setting times
  • Improves surface finish
  • Improves trowellability
  • Reduces honeycombing / cold joint effects

Technical Information

Concreting guidance

The standard rules of good concreting practice for production and placing must be observed when using Sika® Plastiment® PZ 3089in concrete. Refer to relevant standards.
Fresh concrete must be cured properly especially at high temperatures in order to prevent plastic and drying shrinkage. Use Sika® Antisol® products as a curing agent or apply wet hessian.

 

Application

Application Information

Dispensing

Sika® Plastiment® PZ 3089 is added to the gauging water or simultaneously poured with it into the concrete mixer at the batching plant.
Do not add Sika® Plastiment® PZ 3089 directly to the dry mix.
The addition of the remaining gauging water (to fine tune concrete consistency) may only be started after two-thirds of the wet mixing time to avoid surplus water in the concrete.

Compatibility

Sika® Plastiment® PZ 3089 is suitable for mixes containing all types of cement and supplementary cementitious materials such as: Microsilica (Silica Fume), Fly Ash (PFA), GGBS (Ground Granulated Blast Furnace Slag) and the following Sika products:
Sikament®, SikaPump®, Sika®FerroGard®, SikaFume®, SikaFiber®, Sika® Aer, Sika® Stabilizer, SikaControl®
We recommend for trial mixes to be performed to establish the required performance when combining Sika® Plastiment® PZ 3089 with the above products or other admixtures. Please consult our Sika Technical Department.
Consumption

Recommended dosage

1.0 - 1.5 % by weight of binder
Other dosages by weight of binder can be used depending on the mix design, raw materials, climatic conditions and concrete requirements.
Trial mixes must be performed to establish the exact dosage rate required.
