Cebex 130R is a chloride-free powdered plasticising, plasticising, aerating and retarding additive that provides a more impermeable and workable mortar by air-locking and effectively retarding the drying out of the mortar.

Uses

Cebex 130R mortar additive is a plasticising and retaining aerating agent, which is added to mortar (or cement beforehand), for the laying of bricks, plaster or render.

Cebex 130R is specially designed to be used in dry mortars, supplied to site in silos, ready for use, after mixing in a continuous mixer.

Advantages

• Cebex 130R increases the adhesion of hardened mortar on highly absorbent substrates, due to its water retention capacity.
• It facilitates the reduction of both water and cement in sand/cement mixtures.
• It allows a high degree of plasticity and cohesion to be obtained, thus increasing the performance on site.
• As the mass is more manageable, it facilitates the laying of bricks in less time.
• Due to the increase in volume caused by the air occlusion, less sand is needed to achieve the same volume.
• The addition of lime or clayey sands to the mortar to increase plasticity is not necessary.
• Due to the water retention effect, it avoids the risk of shrinkage in the render.

Standards

Cebex 130R complies with UNE-EN 934-3:2004 as an air-entraining / plasticising agent.

Typical dosage

The optimum dosage of Cebex 130R to achieve specific requirements should be determined by testing, using the materials and conditions that will be used in practice.

This allows optimisation of the additive dosage and mix design, providing a full assessment of the mix. The usual dosage is between 0.1 and 0.5 kg of Cebex 130R per 100 kg of cement.

Properties

• Appearance: White powder
• Density: 1.03 kg/litre
• Water soluble chloride content (CI-): ≤ 0.10%.
• Alkali content (Na2O equivalent): ≤ 2.00% by mass
• Primary function: Plasticiser allowing a reduction of the water content
• Secondary function: Increases workability

Mode of use

Mixing

Cebex 130R should be added together with the sand and cement in the premix, to achieve a perfect homogenisation of the additive within the mortar mass.

It should never be added in the mixing water.

A sand granulometry with excessive fines content will lead to a higher quantity of additive needed to achieve the same effect.

It is necessary to take into account the mixing medium, as it directly affects the performance of the additive.

Compatibility

Cebex 130R is compatible with other Fosroc Euco admixtures used in the same mortar mix. All admixtures should be added to the mix separately and should not be mixed with each other before addition. The resulting properties of the mixture, which contains more than one admixture, must be evaluated according to the test procedure recommended in this data sheet.

Cebex 130R is suitable for use with all cements complying with RC-08.

Curing

Cebex 130R is compatible with other Fosroc Euco admixtures used in the same mortar mix. If more than one admixture is used, they must be added to the mix separately and not mixed together prior to being added. The resulting properties of the mixture containing more than one admixture should be checked by pre-testing.

Cebex 130R is suitable for use with all cements complying with RC-08.

Cleaning

Tools and equipment should be cleaned with water immediately after use. Remove hardened material mechanically or with Fosroc Euco Acid Etch.

Storage

Cebex 130R has a storage period of 12 months if kept in original packaging and in a dry place. This period may be reduced by high temperatures and humidity.

Precautions

Safety and Hygiene

Cebex 130R has a low level of toxicity. Avoid contact with skin and eyes, or inhalation of dust. Wear suitable protective clothing, gloves, eye/face protection and respirator.

If skin contact has occurred, wash with plenty of clean water. In case of contact with eyes, rinse immediately with plenty of clean water and seek medical attention. In case of accidental ingestion, seek immediate medical attention. Do not induce vomiting.
