Sika® Plastiment® XR

WATER REDUCING AND SET RETARDING ADMIXTURE

Sika® Plastiment® XR is a water reducing and set retarding admixture. Sika® Plastiment® XR meets the requirements of ASTM C494/AASHTO M 194, Type B & D.

Sika® Plastiment® XR is effective in hot weather conditions to offset the accelerating effects of high ambient and concrete temperatures by slowing the cement hydration and controlling the heat of hydration. Initial set times are delayed, allowing time for proper placement and finishing without cold joints. Hot weather concreting practices as specified in ACI 305 - Guide to Hot Weather Concreting should be followed.   Sika® Plastiment® XR also provides the following benefits:    ▪ Increased flexibility in planning and scheduling concrete pours, ▪ Improved workability and slump retention, ▪ Improved finishing characteristics, ▪ Reduced risk of thermal cracking in mass concrete pours, ▪ Reduced water content, increased ultimate compressive and flexural strengths.    Sika® Plastiment® XR does not contain intentionally added chlorides.

Usage

Sika® Plastiment® XR can be used in concrete when a controlled delay in set time or increase in slump retention is desired. Sika® Plastiment® XR can be used in all types of concrete applications and is effective in concrete containing Portland Limestone Cement (PLC/Type IL) and supplementary cementitious materials.

Application

Application Information

Mixing

Measure the required quantity manually or by automated dispenser. Add Sika® Plastiment® XR directly into the freshly mixed concrete, or as an integral material in the batching cycle. Do NOT mix with dry cement. Sika® Plastiment® XR may be dispensed on-site directly prior to placement. Care must be taken to mix thoroughly. When used in combination with other admixtures dispense each admixture separately into the mix.

  

Compatibility: Sika® Plastiment® XR can be used in combination with other Sika admixtures and can be successfully used in mix designs utilizing supplementary cementitious materials.

 
Consumption

Recommended Dosage

The typical dosage rate of Sika® Plastiment® XR will vary up to 6 fl oz / 100 lb. (325 mL / 100 kg) of cement or cementitious materials. Various factors will affect the dosage rates.

  

Trial mixes with the actual materials should be conducted to determine the required dosage for optimum performance. The required dosage for a mix design may change with fluctuations in the ambient temperature.

  

To the extent specialized materials are used, extreme ambient temperatures are encountered, or for other unusual project conditions, dosage rates outside the typical range may be required. For dosage rates outside the typical range, please contact your local Sika representative or the Sika Technical Services Department at 1-800-933-7452.
