WHAT IS THE PHENOMENE OF EFFLORESCENCE?

The phenomenon of efflorescence challenges semi-dry precast concrete producers daily. It generally occurs with certain ratios of calcium hydroxide and water in the presence of air, whereby these conditions arise through the combination of concrete mix design, the curing process and stocking.

To effectively reduce efflorescence and to ensure a constant, durable concrete surface quality it is necessary to apply an efflorescence reducing admixture, also known as antiefflorescence admixtures.
