FAQ
Frequently asked questions about ordering
What information is required to order ready-mixed concrete?
Quantity, strength class, consistency, placing time and application details are shared as part of the order specification.
Technical order criteria (TR)What does a class such as C25/30 describe?
It identifies the concrete compressive-strength class. The suitable class is determined together with the structural element and project conditions.
Concrete classes (TR)What does the consistency class (S3, S4) describe?
It describes the workability of fresh concrete during transport and placing, and is considered together with the placing method.
Consistency classes (TR)How is the exposure class handled?
The service environment is assessed through conditions such as moisture, chlorides, freeze-thaw, chemical attack and abrasion.
Exposure classes (TR)What does site preparation before placing include?
Formwork, access, placing equipment, the site crew and initial curing preparation are completed before the pour.
Pre-pour preparation (TR)What information does dispatch planning require?
Placing time, vehicle access, placing order and up-to-date site information should be shared.
