Protection of concrete products to prevent efflorescence

Efflorescence that occurs on products made from low-slump concrete is not only an unsightly phenomenon for the client but also a significant cost driver for the producer when it comes to complaints and the need to remove affected pavements.

The causes of efflorescence have been thoroughly researched for years. Many parameters, such as the cement recipe, mixing technique, water/cement ratio and curing conditions, have an influence on its formation and interact with each other. It is difficult to determine which of these factors is the most influential, and which production steps would have to be...
