ASR, known as Alkali-Silica Reaction or “Concrete Cancer”, is starting to alarm pool owners in Austin. A recent Trouble Free Pool forum thread, “ASR – Concrete Cancer – Austin, TX,” serves as evidence, with several residents voicing their concerns and sharing experiences related to this destructive chemical reaction.
Diving Deeper into ASR
ASR is a reaction within concrete structures, causing significant deterioration. It stems from the chemical interaction between the alkalis in Portland cement and certain reactive silica types found in some aggregates. When exposed to water, this reaction can lead to expansive gel formation, resulting in concrete cracking. Builders unfamiliar with ASR or who neglect to take preventive steps risk the structural integrity of their pools.
