Use of product
- Foundation, underground, and sanitation works.
- Civil engineering (structures and roads).
- Reinforced and non-reinforced, precast or prestressed concrete, steam-cured and self-curing
- Construction works (residential, commercial, and industrial buildings).
- Cement-derived products.
Specific and general recommendations
- For work in the rain, hot weather, high winds, or freezing conditions, use standardized and appropriate admixtures.
- Pouring should be regular and continuous in thin layers.
- The concrete drop height should not exceed 1 meter to avoid segregation. Beyond this height, it is essential to plan for the use of a chute at a suitable height, or a feeding chimney
- Adjust the vibration of the concrete to its consistency to achieve optimal compaction without segregation.
- Ensure adherence to setting times during the delivery of fresh concrete.
