XA3: NEXT.BETON IS
SEWAGE AND WASTE-WATER-COMPETENT
MAXIMUM ACID RESISTANCE THANKS TO HIGH XA3 COMPETENCE
Particularly in the waste-water sector, sewer systems are subject to increasing exposure due to industrial influences. With the aim of achieving the resistance of exposure class XA3, elaborate additives, coatings and installations are currently made to increase conventional concrete from XA2 to XA3. With next.beton duct systems, there is no need for this effort. The homogeneous material used throughout ensures maximum chemical resistance, which is why no additional coatings or subsequently installed components are needed to achieve XA3 resistance.
HOW CAN THE HIGH ACID RESISTANCE OF NEXT.BETON BE EXPLAINED?
next.beton sewer systems are more resistant to chemical attack, as they do not contain lime, which can dissolve on contact with acids. With regard to chemical behaviour, results are available from the University of Queensland (Australia), in which EFC® concrete with the binder system used performed correspondingly well compared to cement-bound comparative concretes. The sulphate resistance was proven by tests carried out by AECOM Australia Pty Ltd. The chemical resistance tests are also part of the approval by the German Institute for Building Technology (DIBt).
THE ADVANTAGES OF NEXT.BETON AT A GLANCE
By using a cement-free binder, up to 70 percent of CO2 emissions can be saved in the production of next.beton.
In the production of next.beton, energy-intensive cement is replaced by a geopolymer binder – completely without any technical or qualitative losses.
High acid and sulphate resistance
Due to its lime-free composition, next.beton can be used for XA3 applications without the need for costly additives, coatings or internals.
