Crystalline admixtures are typically added all through batching of the concrete to decreased permeability. The response requires position when exposed to drinking water and un-hydrated cement particles to variety insoluble needle-formed crystals, which fill capillary pores and micro-cracks within the concrete to block pathways for h2o and waterborne contaminates.
Polymer concretes are often useful for the fix and building of other applications, like drains.
