Fosroc Cebex 100

Fosroc Cebex 100 is a plasticised expanding grout admixture (formerly known as Conbex 100). Pack Size: 25kg

Product Description

Cebex 100 is supplied as a powder admixture. The material is a combination of a plasticising agent and a gas producing expansion medium. The plasticising 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. Sufficient restrained expansion is developed to ensure a high degree of interfacial contact.  

Product Uses

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

Product Advantages

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

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 admixture must be iron-free and chloride-free and shall be added to the grout in the proportions 225 g of admixture per 50 kg of cement. The admixture shall provide an expansion of up 4% in the plastic grout, by means of a gaseous system. The admixture must be stored, handled and mixed strictly in accordance with the manufacturer’s instructions.
