"kuring" = the cleaning of the cement. One part of cleaning is to neutralize excess alkalinity; the other part is to leach away excess alkalinity.
The cleaning process transforms into "cycling". As the beneficial bacteria colonize the surface of the rock, they seal it up, and any sealed in calcium will have an opportunity to gradually bond chemically with the concrete making it harder and stronger over time.
