Sika® Plastiment®-201 AE

WATER REDUCING AND RETARDING CONCRETE ADMIXTURE

Sika® Plastiment®-201 AE is a water based, liquid, set-retarding admixture that slows the chemical action of cement hydration, delaying the initial set in direct proportion to the dosage used. After the planned delay in initial set, hardening develops at an accelerated rate. Suitable for use in hot and tropical climatic conditions.

Sika® Plastiment®-201 AE provides the following beneficial properties:
▪ Controlled setting times
▪ Increased setting time in hot weather
▪ Accelerated hardening after setting
▪ Improved workability without increased water content
▪ Reduced water content without loss of workability
▪ Increased strengths
▪ Reduced shrinkage and creep
▪ Long lasting control of slump loss
▪ Superior surface finish
▪ Does not contain chlorides or other steel corrosion promoting ingredients

Usage

Sika® Plastiment®-201 AE is used as a water reducing and set retarding admixture in structural and mass concrete where a controlled extension of setting time is required, such as:
▪ Large volume pours
▪ Avoidance of cold joints
▪ Construction joints without formwork
▪ Long hauls
▪ Difficult placing conditions
▪ At elevated ambient temperatures

Technical Information

Concreting guidance

The standard rules of good concreting practice for production and placing must be observed when using Sika® Plastiment®-201 AE 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

Dispensing

Sika® Plastiment®-201 AE is added to the gauging water or simultaneously poured with it into the concrete mixer at the batching plant.
Do not add Sika® Plastiment®-201 AE 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.

Compatibility

Sika® Plastiment®-201 AE may be combined with all types of Portland cement, concretes containing pozzolanic materials such as; GGBS, PFA , micro-silica and the following Sika product ranges:
▪ Sika® ViscoCrete®
▪ SikaPlast®
▪ Sikament®
▪ Sika Aer®
▪ SikaPump®
▪ Sika® FerroGard®-901
▪ SikaFume®
▪ SikaFiber®
▪ Sika Aer®
▪ Sika® Stabilizer
▪ Sika®-1 WT
We recommend to perform trial mixes to establish the required performance when combining Sika® Plastiment®-201 AE with the above or other admixtures.
Please consult our Sika Technical Department.
Consumption

Recommended dosage

0.2 - 2.0 % 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.
