Concrete treatment contains aggressive chemicals

A Belzona Polymerics product story
Edited by the Engineeringtalk editorial team Jul 8, 2008

Belzona Polymerics' concrete treatment system has been used to resist corrosion in the power industry and in demineralised water treatment plants.

Belzona Polymerics has developed a solution to prevent the detrimental effects of aggressive chemical attack and leakage within concrete chemical containment areas.

Bunds, sumps, plinths, channels and sluices are susceptible to attack from chemicals.

If the deterioration is not addressed the structural integrity of the concrete will be seriously undermined, with the potential for chemical leakage and structural failure, resulting in environmental damage.

Gordon Cairns, National Sales Manager for Belzona said, "These costly after-effects can easily be avoided by using a Belzona chemical containment repair and protection system".

"This Belzona solution is a cold applied cost-effective repair composite that has proven results within the power industry but has been particularly successful in demineralised water treatment plants".

Concrete chemical containment structures can be repaired and protected against chemical attack.

This preservation and long-term protection of the concrete eliminates possible structural failure and loss of chemical.

An inspection of a discharge sluice at a nuclear power station in the UK found the concrete to be suffering from severe deterioration due to acid attack.

A previously applied cementitious repair screed had been damaged by an impact, which caused peaks and troughs in the channel.

The acid had penetrated the concrete, attacking the underlying substrate and leaving large voids.

Belzona was able to provide a cost-effective solution to prevent chemical attack and reduce further deterioration of the sluice channel.
