It is a commonly held belief that Silicate sealers being highly alkali in nature increase the speed of AAR / ASR concrete deterioration and rightly so.

By comparison Radcon waterproofing stops AAR / ASR concrete expansion totally by stopping water entry critical to this ongoing reaction.

Furthermore long term testing was conducted using Radcon as an admixture by Queensland Department of Main Roads, Australia with reactive aggregates present.

The testing proved conclusively that the presence of reactive aggregates with Radcon dispersed in the mix reduced the AAR / ASR reaction in both ash free concretes and blended concretes.
