Cebex SP is a chloride-free, expansive, superplasticising powder admixture that provides a more workable, shrinkage-free mortar for cementitious mixes.

This allows optimisation of the additive dosage and mix design, providing a complete assessment of the mix. Typical dosage is between 0.3 and 0.9 kg of Cebex SP per 100 kg of cement.

Uses

  • Cebex SP mortar and cement additive is a superplasticiser which is added to the mortar (or cement beforehand).
  • Cebex SP is specially designed for use in dry mortars or cements delivered to site in silos, ready for use, after mixing in a continuous mixer.

Advantages

  • Facilitates water reduction in sand / cement mixtures.
  • Allows a high degree of plasticity and cohesion to be obtained, thus increasing performance on site.
  • It allows to counteract the shrinkage produced by the cement in a controlled way.
  • Due to the water retention effect, it minimises the risk of shrinkage.

Properties

  • Appearance: Light brown
  • Density: 1.03 kg/litre
  • Water soluble chloride content (CI-): ≤ 0.10%.
  • Main function: Produces very fluid cementitious mortars

Directions for use

Mixing

Cebex SP should be added together with the cement in the premix, in order to achieve a perfect homogenisation of the additive within the mass.

It should never be added in the mixing water. The mixing medium must be taken into account, as it directly affects the performance of the additive.

Typical dosage

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

Compatibility

Cebex SP is compatible with other Fosroc Euco admixtures used in the same mortar or cement mix. If more than one admixture is used, they should be added to the mix separately and not mixed together prior to addition. The resulting properties of the mixture containing more than one admixture should not be mixed together prior to addition.

Cebex SP 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 SP 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 SP 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.
