Storage of concrete admixtures and mortar admixtures (BZM) according to EN 934-2
Concrete admixtures and mortar admixtures are liquids hazardous to water. When storing these liquids in tanks, the local regulations must be observed. Dehoust tanks have the approval of DIBt.
With this approval, the operator can be sure that the requirements such as stability, tightness and material resistance are met.
Depending on the storage volume, different requirements are placed on the secondary protection (collecting basin/dike or collecting space).
Single-walled PE storage tanks with dome (serie PE-D) are approved for the common concrete liquefiers (BV), superplasticizers (FM) and setting retarders (VZ), just like our plastic dikes.
The two-walled storage tanks TrioSafe 1100 and TrioSafe 1500 are also approved for BZM and do not require an additional collecting tray/dike.
