The indoor moisture variation might be modulated by suitable
SAP-containing composite materials, since they are able to quickly
respond to humidity changes [16]. For instance, SAP-containing
mortars showed interesting moisture buffering values (MBVs),
being classified as ‘‘good or excellent’’ according to the Nordtest
protocol [17]. Their performance is superior than the one achieved
with porogene additives or lightweight fillers, such as vermiculite,
perlite, aluminium powder or sodium olefine-sulphonate [13–15].
However, SAP particles exert a negative impact on the flowability
of the mortar mixes [13–15]. This workability loss is commonly
corrected by increasing the water dosage, but this action will
induce deleterious effects on functional properties (e.g., mechanical
strength) of the hardened mortar. For that reason, systematic
studies that clarifies the influence of each individual component
and the eventual synergetic action on a particular property need
to be carried out [18,19].
