Plasticised expanding grout        admixture


Cebex 100 is an admixture for cementitious grouts where a reduced water/cement ratio and positive expansions are required. Applications include bed grouting, duct grouting, non-shrink infilling and jointing.


  • Gaseous  expansion  system  compensates  for  plasticshrinkage  and  settlement  in  properly  designedcementitious  grout.
  • Reduced water/cement ratio mixes in the grout mix ensure slow permeability and long term durability in service.
  • Gives grout high fluidity with low water/cement ratio, thusmaking placement or injection of the grout easy.
  • No metallic iron content to corrode and cause staining ordeterioration due to rust expansion in the grout.
  • Composition  allows  high  early  strength  development  ingrouts, without  the  use  of  chlorides.


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 shrinkage of the grout and aids stability and cohesion.

Specification clauses

Performance specification

All grouting (specify details and areas of application) must be carried out with a cement based grout incorporating a plasticised, expanding powder admixture. The grout admixture must be iron-free and chloride-free and shall be added to the cement grout in the proportion of 225g per 50kg of cement. The grout admixture shall provide an expansion of up to 4% in the plastic grout, by means of a gaseous system. The grout admixture must be stored, handled and mixed strictly in accordance with the manufacturer's instructions.

Application instructions


For best results a mechanically powered grout mixer must be used. For quantities upto 50kg, a slow speed drill fitted with a hig shear paddle is suitable. Large quantities will require a high volume drum mixer. It is essential that machine mixing capacity and labour availability is adequate to enable the grouting operation to be carried out continuously. This may require the use of a holding tank with provision for gentle agitation to maintain fluidity. The selected water content should be accurately measured into the mixer. The cement (and sand if required) shall be slowly added to Cebex 100. Mixing shall be continued for 5 minutes, making sure that a smooth even consistency is obtained. 


It shall be ensured that areas to be grouted are clean, sound, and then pre-wetted. The unrestrained surface area of the grout must be kept to a minimum. The grout shall be placed within 20 minutes of mixing to gain the full benefit of the expansion process. Usual placing or pumping procedures shall be adopted ensuring a continuous operation. 

On completion of the grouting operation, any exposed areas which are not to be cut back should be thoroughly cured by means of water application, concure*  curing membrane or wet hessian.



Cebex 100 is incompatible with High Alumina Cement.

  • To minimise permeability and increase the waterproofing properties of concrete and cement sand mortars for critical applications like roof slabs and screeds, basements, external plastering, bathroom floors, water tanks, sumps, drains etc.

  • Liquid admixture: Instant and complete dispersion throughout the mix. Uniform waterproofing throughout concrete matrix.
  • High efficiency: Dramatic reduction in permeability of concrete/ mortar.
  • Improved workability: Improves compaction of concrete and mortar, even where harsh sands or aggregates are used.
  • Improved concrete quality : Minimises porosity and honey combing. Produces dense homogenous concrete.

Standards Compliance:
  • Conplast WL conforms to IS:2645-2003.

  • It is based on lignosulphonates which mixes readily with water and therefore disperses evenly. 
  • It waterproofs by improving the quality of the concrete or mortar. 
  • It reduces the water demand for required workability and minimises segregation and bleeding. 
  • Thus it is more efficient compared to traditional powder waterproofers as its use results in two fold improvement of concrete or mortar.

  • Chloride content : As per IS:2645-2003
  • Compatibility : Can be used with all types of cements,including pozzolanic but not High Alumina Cement.
  • Permeability to water : Less than 15% as compared to 50% max. allowable under IS:2645compared to control sample.
  • Setting Time: No significant effect on setting time of concrete or mortar.
  • Compressive Strength : Maintains compressive strength equal to control concrete or mortar and can even improve on strength property if full advantage of water reduction potential is utilised.
  • Workability: Improves workability at reduced water cement ratio

Application instructions:
  • Mortar: Conplast WL is ideal for use with all sand/cement mortars where it is required to reduce permeability to a minimum.
  • Concrete: Conplast WL is recommended for all general mass concrete work where, due to harsh aggregates, difficulty of compaction or mix control, the risk of porosity and permeability must be minimised. Eg. Basements, bund walls, tanks, balcony, floor and roof slabs.
  • N.B.: The minimum dosage is 125ml and the maximum is 200ml per 50kgs of cement. If maximum dosage is used a minimum of 15% water should be reduced to ensure no loss in strength. Site trials shall be carried out to arrive at the optimum dosage.
  • The required quantity of Conplast WL is measured and stir into the first or second bucket of water
  • Conplast WL water mixture shall be added to the concrete or mortar and mixed thoroughly.
  • Mixing shall be continued and further water shall be added until the required workability is obtained.

Fosroc Conplast P211 Plasticizing Admixture is a chloride free water        reducing admixture based on selected sugar-reduced  ligno sulphonates. It is supplied as a brown  solution which instantly disperses in water. It disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively and improving the consistency of the concrete. This produces higher levels of workability for the same water content, allowing benefits such as water reduction and increased  strengths to be taken.


  • To improve the effectiveness of the water content of a concrete mix.
  • At higher dosages to provide a cost effective means of reducing concrete permeability and thereby reducing water penetration.

  • Allows specified strength grades to be met at reduced cement content or increased workability.
  • Water reduction significantly improves compressive strengths at all ages and enhances durability through the production of low permeability concrete.
  • Minimises the risk of segregation and bleeding and assists in the production of a dense, close textured surface, improving durability.
  • Chloride free, safe for use in prestressed and reinforced concrete
