Cebex 100

Products Catalogue

Description

Cebex 100, a plasticised expanding grout admixture is supplied  as a powder. The material is a combination of a plasticising  agent and a gas producing expansion medium. The plastisicing agent allows the use of a reduced water/cement ratio with  consequent increased strengths and durability. The expansive  medium counteracts the natural settlement and plastic shrink age of the grout and aids stability and cohesion.

Advantages

  • Gives grout high fluidity with low water/cement ratio, thus making placement or injection of the grout easy.
  • Reduced water/cement ratio mixes in the grout mix ensures low permeability and long term durability in service.
  • Gaseous expansion system compensates for plastic shrinkage and settlement in properly designed cementitious grout
  • Composition allows high early strength development in grouts, without the use of chlorides.
  • No metallic iron content to corrode and cause staining or deterioration due to rust expansion in the grout.

Properties

Properties

Chloride content

Nil as per BS:5075

Compressive strength

The plasticising action of Cebex100
allows reduction of the water cement
ratios of cementitious grouts
whilst maintaining flow properties.
This gives improvement in strength
and long term durability when
cured under restraint.

Setting Times

Cebex 100 does not signifi cantly
alter the setting times of cement
based grouts.

Expansion Characteristics

The controlled positive expansion in
unset grouts incorporating Cebex
100 overcomes plastic settlement
when measured in accordance with
ASTM C827. An unrestrained
expansion of up to 4% is typical.

Time for expansion

15 mintues - 2 hours. Temperatures
above 20°C may slightly reduce
these times.

Compatibility

Cebex 100 is compatible with all
types of portland cement.
Cebex100 may be used in mixes
containing certain other Fosroc
admixtures. Fosroc shall be
contacted for further information.
