CCM gmbh ALGT 627-10

• ALGT 627 10 is extremely well suited as hydrophobic concrete additive for the manufacturing of paving stones, concrete slabs and prefabricated concrete elements.
• ALGT 627 10 improves concretes compaction, regulates the capillary properties of the concrete and reaches a durable and long lasting structure which is effective in reducing water absorbtion; this is especially evident where the fully cured concrete is used to stop rinsing moisture.
• ALGT 627 10 protects the concrete against lime efflorescences and against the growth of micro o rganisms (moss, algae, fungus) on and in the structure. The final concrete product remains vapor diffusive.
• ALGT 627 10 minimizes sticking to molds and pattern stamps and it reduces the adhesion of concrete to mixers and associated equipment by using a highly effective non stick additive.

• Stir the ALGT 627 10 concrete additive thoroughly before use.
• Add the additive to the mixing water. The mixing time of the liquid should at least be 1 minute.
• Do not add ALGT 627 10 to the dry concrete mix.

• The recommended dosage of ALGT 627 10 is between 1% 2% of the binder content ( cement).
• Example. To create a concrete or cement mix.
  • Take 1kg of cement powder. Mix this with 2kg of sand and 2kg of aggregate. Mix thoroughly. Add 10 20ml of the 627 10 to 1 liter of water (the amount of water will alter depending on the nature of the concrete required Stir this liquid for a minimum of 1 minute to ensure full dispersion. Add this newly created water + additive to the concrete Mix a s normal.
  • Please note that in this ex ample, th 1kg of cement powder plus 1 2% of 627 10 is the crit ical ratio. If the mixture was based on 50kg of cement powder you would add between 500ml to 1.000ml of 627-10, dependent of the perfance level required.
• Please use different doses for two layer concrete (core layer and face layer):
• Example:
  • core concrete: approx. 1%
  • face concrete: approx. 2%
• The thin face layer ( 1 cm) doesn’t significant alter the additive costs per square meter.

Please check the product suitability under production conditions, in advance of an industrial application and adjust the optimal dosing quantity during a suitability test.
