Applications include bed grouting, duct grouting, non-shrink infilling and jointing. Advantages Gaseous expansion system compensates for plastic shrinkage and settlement in properly designed cementitious grout. 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 Cebex is a suitable pressure grouting admixture complying with BS Part , Section 8. Description Cebex , 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 expansive medium counteracts the natural settlement and plastic shrinkage of the grout and aids stability and cohesion. Application instructions Mixing For best results a mechanically powered grout mixer must be used.

For quantities up to 50kg, a slow speed drill fitted with a high shear paddle is suitable. Large quantities will require a high volume drum mixer. It is essential that machine mixing capacity and labor 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 Mixing shall be continued for 5 minutes, making sure that a smooth even consistency is obtained. Application 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.

Precautions Health and Safety instructions Cebex is of low hazard. Contact with the skin and eyes, or inhalation of dust should be avoided. In case of contact with skin, it shall be washed with clean water. In case of contact with eyes, it shall be rinsed immediately with plenty of water and medical attention shall be sought immediately.

You are on page 1of 4 Search inside document Conbextra GP2 4S General purpose, free flow, high strength, nonshrink, cementitious grout Uses Conbextra GP2 4S is used for general purpose grouting where it is essential to eliminate shrinkage when completely filling the void between a base plate and a substrate. Such an application would be the grouting of a stanchion base plate. It can also be used for anchoring a wide range of fixings. These include masts, anchor bolts and fence posts. The addition of a controlled amount of clean water produces a free flowing, non-shrink grout for gap thicknesses up to mm. Conbextra GP2 4S is a blend of Portland cement, graded fillers and chemical additives which impart controlled expansion in the plastic state whilst minimising water demand. The low water demand ensures high early strength.
