Sika® Plastiment® R 148

(former MasterPozzolith® R 148)

WATER REDUCING AND SET RETARDING

Sika® Plastiment® R 148 is a liquid admixture based on modified lignosulphonates and synthetic materials.

The admixture delays the initial hydration of cement thus retarding setting times and extending workability. However, the hardening process is not substantially modified, so that an increase in strength is obtained in proportion to the reduction in mixing water.

The addition of Sika® Plastiment® R 148 increase concrete workability without decreasing concrete strength.

The use of Sika® Plastiment® R 148 with concrete increases cohesion and considerably reduces segregation.  

  • High workability at high temperature - Short placement time. Saves time and labour.
  • High water reduction - High impermeability and strength. Improves durability
  • Extended workability - Retardation of setting times without loss in strength
  • Easy and rapid pumping operations - Higher ultimate strength and with better surface finish.

Usage

Sika® Plastiment® R 148 is compatible with the following:
• All types of concrete where retardation of set and improved performance are required.
• Improving pumped concrete and conventionally place concrete.
• Improving plain, reinforced, precast, prestressed, light weight or standard weight concrete.

Advantages

  • High workability at high temperature - Short placement time. Saves time and labour.
  • High water reduction - High impermeability and strength. Improves durability
  • Extended workability - Retardation of setting times without loss in strength
  • Easy and rapid pumping operations - Higher ultimate strength and with better surface finish.

Product Information

Shelf Life

12 months

Storage Conditions

Stored at temperatures above 5°C, in tightly sealed original drums. If found to be frozen, thaw it and reconstitute by stirring.
Technical Information

Specific Advice

The lowering of water/cement ratio reduces the porosity resulting in a more dense impermeable concrete. Thus, the ingress of aggressive agents can be reduced considerably thereby extending durability.

 

Application

Application Information

Dispensing

Sika® Plastiment® R 148 is a ready-to-use liquid product. It is introduced into the mixer at the same time as the mixing water.
Consumption

Consumption

Vary between 0.2 and 0.6 litres/100kg of cementitious material, depending on the specific working conditions.
