Moisture issues in concrete slab

[RCConcrete Consulting]

Thankfully Hawaii is pretty much permanently humid..it's all relative..no pun intended... The dryness is a relative factor and it is actually best if concrete never drop below an internal r.h. of 80% which allows the concrete to continue curing..the longer concrete cures, the denser it becomes, the the relative amount of moisture available in the pores becomes less and less of an issue..the denser the concrete, the smaller the pores and the fewer remain connected...
