Crystalline admixtures are usually included during batching of the concrete to lessen permeability. The reaction will take position when exposed to h2o and un-hydrated cement particles to variety insoluble needle-formed crystals, which fill capillary pores and micro-cracks from the concrete to block pathways for drinking water and waterborne contaminates.
