This mixture is then poured into the desired location or into molds and left to harden. Once the concrete is hardened it creates a very strong, and stable structure that can be permanent.
The alkaliâsilica reaction (ASR) is a reaction which occurs over time in concrete between the highly alkaline cement paste and reactive non-crystalline (amorphous) silica, which is found in many common aggregates and sufficient moisture.his reaction causes the expansion of the altered aggregate by the formation of a swelling gel of calcium silicate hydrate (C-S-H). This gel increases in volume with water, and exerts an expansive pressure inside the material, causing spalling and loss of strength of the concrete, finally leading to its failure.
