SikaGrout-234 - Shrinkage Compensated Setting Mortar - Sika

SikaGrout-234 is a high-performance, shrinkage-compensated sealing mortar with reduced environmental impact.
Ready-to-use hydraulic mortar.
After mixing with water, a mortar of fluid consistency is obtained, with compensated shrinkage.

Features

• Reduces the carbon footprint thanks to the use of raw materials from recycling to replace part of the Portland cement.
• Resists sea water and sulphate water.
• Free of chlorides and metallic particles.
• Compensated shrinkage, low heat release.
• High mechanical resistance in compression and bending, including in the short term.
• Excellent adhesion to concrete, mortar and steel.
• Ensures a monolithic connection and is perfectly resistant to shocks and vibrations.
• Resists changes in humidity or temperature; water and oil resistant.
• Rapid return to service of equipment thanks to its high initial resistance.
• Can be loaded for sealing large volumes (outside the scope of the NF mark).
• Complies with standard NF EN 1504-6, for anchoring rebar for reinforced concrete.
• Unloaded application thickness: 12 to 200 mm per pass.

Application areas :

• Sealing anchor bolts or reinforcing bars.
• Precision sealing of industrial equipment subjected to shocks or vibrations.
• Sealing railway tracks or overhead cranes.
• Timing of turbines, alternators, compressors, generators, machine tools.
• Wedging of beams or constructions of bridge end supports.
• Assembly of prefabricated metal, reinforced concrete or prestressed concrete elements.

Application

1. Mix the 25 kg bag with 2.5 to 3.2 l of clean water.
   The normalized mixing rate (NF tests) is 2.5 liters of water per 25 kg bag.
2. Introduce about 2/3 of this water into the mixer.
3. Gradually add the SikaGrout-234 powder while mixing to avoid the formation of lumps.
4. Then pour in the rest of the water and let the mixer run for at least 3 minutes.
5. Loaded product (excluding NF):
   It is possible, for the execution of large-scale or large-volume seals, to add siliceous sands and gravels, provided that they are clean, and of suitable granulometry.
   For example, add 12.5 kg of Charge C or sand (maximum grain size 8 mm) with 1 bag of 25 kg of SikaGrout-234.
   Mix with 3.4 liters of clean water.

Consumption

A 25 kg bag of SikaGrout-234 mixed with 2.5 liters of water makes it possible to make approximately 12.5 liters of mortar.
To fill a volume of one liter of sealant, the consumption is therefore about 2 kg of SikaGrout-234.

NF mixing rate: 2.5 liters/25 kg bag
When using loaded SikaGrout-234 (outside the scope of the NF mark) at a ratio of 1/0.5, consumption is reduced to around 1.3 kg of SikaGrout-234 per litre.

Conditioning
