It is recommended to add Anti-CRAK® HD into wet concrete during the last stage of mixing, or directly into a ready mix concrete truck on the jobsite. For dry mix applications, fibers can be added in the dry premix.
Anti-CRAK® HD all lengths: Packed in plastic bags (18 kg).
Anti-CRAK® HD 6, 12, and 18mm: Packed in individual 600g and 1lb paper bags (water dispersible)
Specific packaging can be negotiated based on volume applications.
Anti-CRAK® HD should be stored away from heat and moisture, and must stay in its original packaging. Optimum conditions are temperature between 15°C and 35°C (59ºF to 95ºF) and humidity between 35% and 65%. If the product is stored at lower temperatures it is advisable to condition it in the workshop for at least 24 hours before use, to prevent condensation.
