Water rise in concrete due to capillary
Water rise in concrete due to capillary
(OP)
Is there any relationship between type of concrete and water rise due to combination of capillary, absorption and various pressures? Is there a maximum distance which water will rise through concrete due to capillary? Thanks. Any reference would be greatly appreciated.

Vapor pressures and vapor drive will have some effect on the rise, though that primarily affects thinner sections such as floor slabs.
The pore structure coupled with the absorption of the coarse aggregate will have the greatest effects on capillary rise.

My biggest concern was vapour movements through the slab and its relationship with flooring failures. What I read so far backs ACI302 requirements for a combination of a drainage layer and a vapour retarder directly under the slab.
