Sika® Plastiment® PZ 384

(former MPozzolith 384)

LOW DOSAGE RETARDING AND PLASTICIZING ADMIXTURE FOR CONCRETE

Sika® Plastiment® PZ 384 is a liquid admixture which acts on the cement particles in the mix, combining the effects of a powerful plasticizer and deflocculating agent with controlled retardation. Suitable for use in hot and tropical climatic conditions.

  • Considerably extends vibration limit of concrete mixes thus reducing incidence of honeycombing and cold joints.
  • Reduces placing problems in hot weather concreting by improving workability and workability retention.
  • Improves trowellability and surface finish.
  • Improves pumpability of concrete.
  • Considerably reduces permeability.

Usage

  • Hot weather concreting where controlled delay to initial set is of prime importance.
  • Ready mix concrete where workability retention coupled with retardation of initial set are beneficial.
  • To improve cohesion, workability and compaction in concretes using poorly graded / shaped fine aggregates.
  • Large slabs or bridge decks, etc. where extension of vibration limits is beneficial to avoid cold joints.
  • As a synergy admixture in combination with a superplasticizer.
 

Advantages

  • Considerably extends vibration limit of concrete mixes thus reducing incidence of honeycombing and cold joints.
  • Reduces placing problems in hot weather concreting by improving workability and workability retention.
  • Improves trowellability and surface finish.
  • Improves pumpability of concrete.
  • Considerably reduces permeability.

Technical Information

Concreting guidance

The standard rules of good concreting practice for production and placing must be observed when using Sika® Plastiment® PZ 384 in 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

Compatibility

Sika® Plastiment® PZ 384 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 384 with the above products or other admixtures. Please consult our Sika Technical Department for further assistance.

Dispensing

Sika® Plastiment® PZ 384 should be added to the concrete mix during the mixing cycle at the same time as the water or the aggregate. Never add Sika® Plastiment® PZ 384 to the dry cement. No extension to normal mixing times is necessary.
Consumption

Recommended dosage

As a general guide to these trials, a dosage range of 200 ml to 600 ml per 100 kg of total binder is recommended as a starting point. Depending on the desired properties, a dosage of up to 800 ml per 100 kg of total binder can be used. Higher dosages may be required when certain combinations of materials and conditions are present. Trials should be conducted to determine the optimum addition rates of Sika® Plastiment® PZ 384, depending on mix design proposed and mix performance requirements.
