Admixtures for concrete products



MULTIPHOB H6 brings about a chemical modification of free calciumions and a certain hydrophobic lining of the capillary pores.

In concrete, concrete hardening agent H6 causes: - a hydrophobic reaction of the capillary pore system. - a reduction in efflorescence and an increase in the resistance to frost and de-icing salt. - a significant colour intensification in coloured concrete goods. - a lubricating effect on account of the plasticizing components, enabling an increase in the surface quality, and so as to positively influence the removal process.

Application Area

  • To create mechanically produced, one-course and coloured concrete goods or face concrete for concrete goods (consistency C0 – C1), like for example, concrete paving blocks, pavement flags, limiting elements and palisades.
  • To produce essentially efflorescence-free concrete goods.
  • To produce coloured concrete goods. If you use concrete hardening agent H6 you do not have to use a concrete liquefier in addition.
