RB-P1 WATER REDUCING PLASTICISER

DESCRIPTION

RB-P1 is a powerful water reducing and plasticizer based on lignosulfonate which disperses the cement particles within a concrete mix. It can be used to improve workability, without the addition of extra water, or to allow reductions in the free water content of the concrete mixture.

APPLICATION FIELDS

  • To increase / extend workability.
  • To increase compressive strength.
  • To effect cement economies.
  • For hot weather concreting.
  • To reduce water content.
  • In pre-stressed concrete.
  • In areas of congested reinforcement where high workability is of benefit.
  • In pre-cast concrete manufacture.
  • In concrete brick and block manufacture.
  • Wherever reduced water content would be of benefit to reduce permeability.
  • In hot weather to extend workability.

FEATURES

  • Significantly improves the workability therefore easing placing.
  • Improves the cohesive properties of the concrete helping to reduce segregation and bleeding.
  • Of particular benefit in hot climatic conditions when used to extend workability.
  • Enables economies in mix designs to be achieved thereby saving cement.

PACKAGING

RB-P1 is available in 220 kg drums and 20 kg gallons.

TECHNICAL SPECIFICATIONS

 

Physical state: liquid

Density: Approximately 1.2 kg/l

Chloride content: According to standard

Color: brown

Minimum consumption temperature: 5 0C

STANDARDS

 

ASTM C494: Types B & D

ISIRI: 2930

DOSAGE

A dosage range of 0.5kg to 1kg per 100kg cement is recommended as a starting point.

Note: don’t use more than 1.2 kg RB-P1 per 100 kg cement.

DIRECTION FOR USE

RB-P1 should be added to the concrete mix during the mixing cycle at the same time as the water and the aggregates. The maximum effect is achieved when the RB-P1 is added after the addition of 50 to 70 % of the water.  Never add RB-P1 to the dry cement. Keep mixing at high rate for 60 seconds in order to complete mixing.

STORAGE

RB-P1 should be stored in original containers and at above 5 degrees Centigrade. If frozen gradually thaw and agitate until completely reconstituted.

SAFETY

RB-P1 is not a fire or health hazard. Spillages should be washed down immediately with cold water. For further information refer to the material safety data sheet.
