Influence of wet concrete on room air

["Timo Sengewald" <timo.sengewald@xxxxxxxxxxxxxxxxxx>]

Dear TRNSYS group,

a current project of ours is the design of building services for an
archive building. In order to decrease the rate of the deteriotation
process of the stored documents it is neccesary to keep the climate
conditions in rather tight boundaries. To ensure this, it would be quite
helpful to know the influence that already solid but still wet concrete
has on the climate of the storage modules. Probably it is important to
dehumidify the building for a long period of one maybe two years until
it is ready to be used. To know how long this dehumidification process
may last and in which condition the inlet air should be, we would like
to simulate these circumstances.

The advanced humidity model of type 56 is able to calculate the buffer
effect of walls. But unfortunately there seems to be no way to set any
initial moisture content.

Does somebody has any hints on literature which deals with the influence
of wet concrete? What possibilities do you know to simulate this effect?

Kind regards,

Timo Sengewald
