CERESIT® CX 15 STRONG is a mortar for high-strength grouting, anchoring and assembly with optimal flowability and working time up to 60 minutes. It is water and frost resistant, so it is a safe solution for indoor and outdoor applications.Available pack size: 25kg
Dirt, anti-adhesive substances and paint coatings must be completely removed. The concrete substrate must be opened- pored, rough and have a good keying structure. Thoroughly pre-wet the concrete, but free of puddles. Check the clearance of mounting element is not less than 20 mm between the edge of mounting hole and anchor.
Add the material into a measured quantity of 2 l of clean water and premix with a compulsory-type mixer or electric drill with stirrer attachment until homogeneous, completely free of lumps. Then add about 0.9 l of water until the appreciate consistency is reached and mix for a further 5 minutes. Apply mortar within 60 minutes. Observe a minimum clearance of 20 mm at every point of the anchoring or of the cavity to be grouted to ensure cavity-free compaction. Perform grouting in continuous and uniform manner.
At clearances 50-100 mm, CERESIT CX 15 STRONG should be mix with approx. 6.25 kg (25% by weight) of the dolomite aggregate fraction 4/8 mm or basalt fraction 4/8 mm or 8/16 mm, water added to the required consistency. The addition of gravel does not affect setting time, but slightly reduces the strength of the anchorage. Therefore, appropriate tests should be carried out earlier on the construction site or the CERESIT Technical Department should be consulted.
CERESIT CX 15 STRONG mortar is intended for grouting steel inserts and anchors in concrete, grouting machine basis, grouting posts, beams support and grouting joints between prefabricated members and in-situ concrete, lintels and wells outlets, for filling openings and recesses in concrete and cavities in floor.
