The standard rules of good concreting practice for production and placing must be observed when using Sika® Plastiment® PR-2002 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.

Sika® Plastiment® PR-2002 may be combined with all types of Portland cement (OPC and SRC), concretes containing pozzolanic materials such as GGBS, PFA, micro-silica and the following Sika products:
Sikament® and Plastiment® ranges;
SikaPump®, Sika® FerroGard®-901, SikaFume®, SikaFiber®, Sika Aer®, Sika® Stabilizer, Sika®-1 WT, Sika® WT-10
We recommend to perform trial mixes to establish the required performance when combining Sika® Plastiment® PR-2002 with the above products or other admixtures. Please consult our Sika Technical Department.

Sika® Plastiment® PR-2002 is added to the gauging water or simultaneously poured with it into the concrete mixer at the batching plant.
Do not add Sika® Plastiment® PR-2002 directly to the dry mix.
For optimum utilization we recommend thorough mixing at a minimum wet mixing time of 60 seconds.
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.

0.3 - 0.6 % by weight of binder
Higher 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.
