Description

Fosroc Cebex 100 – Non-Shrink Grout Admixture

Fosroc Cebex 100 is a powder admixture combining a plasticizing agent and a gas-producing expansion medium. The plasticizer reduces water/cement ratio for improved strength and durability, while the expansive medium counteracts plastic shrinkage, ensuring maximum contact and stability in grouts.

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

Advantages:

• Gaseous expansion system compensates for plastic shrinkage and settlement in properly designed cementin- pious grout.
• Reduced water/cement ratio 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

Standards compliance:
Fosroc Cebex 100 is a suitable pre-stressing grout admixture when complying with BS 8110 Part 1, 1985, section 8.9.4.6.

Specification
Performance specification
All grouting (specify details and areas of application) must be carried out with a cement-based grout incorporating a
plasticized, 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 to 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.

Supplier specification:
All grouting (specify details and areas of application) must be carried out using a cement-based grout, incorporating
Cebex 100 manufactured by Fosroc and applied strictly in accordance with the manufacturer’s technical data sheet.

Instructions for use:

Mixing

For best results Fosroc MR3 mixer must be used. For quantities up to 50 kg a slow speed drill fitted with a high shear paddle is suitable. Larger quantities will require a high shear vane 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. Slowly add the cement (and sand if required) and Cebex 100. Mix continuously for 5 minutes, making sure that a smooth even consistency is obtained.

Application

Areas to be grouted should be prepared to ensure substrates are clean, sound, and then pre-wetted. The unrestrained
surface area of the grout must be kept to a minimum. Place the grout within 20 minutes of mixing to gain the full benefit
of the expansion process. Adopt usual placing or pumping procedures ensuring a continuous operation.
Curing
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, Concore* curing membrane or wet hessian.

Cleaning

Grouts mixed with Fosroc Cebex 100 should be removed from tools and equipment with clean water immediately after use. Remove cured material mechanically or with Fosroc Acid Etch*†
.
Limitations
Fosroc Cebex 100 is not compatible with High Alumina Cement.

Storage
Fosroc Cebex 100 has a shelf life of 12 months if kept in a dry store in its original packaging. High temperature and humidity
storage may reduce this period.
Precautions
Health and safety
Fosroc Cebex 100 is of low hazard. Contact with the skin and eyes, or inhalation of dust should be avoided. Wear suitable protective clothing, gloves, eye/ face protection and dust mask. After contact with skin, wash off with clean water. In case of contact with eyes, rinse immediately with plenty of water and seek medical attention.
