The ability of superabsorbent polymer (SAP) particles to absorb
large amounts of liquid without dissolving allowed extensive
worldwide industrial applications. In civil construction, the use of
SAP in cement-based material or composites has been growing,
due to several advantages obtained by the use of such particles,
as described below. According to Jensen and Hansen [1], SAP can
be used as an alternative to the internal curing agent for the
prevention of self-desiccation, avoiding crack formation. Other
benefits include the increment of hydration and durability and
the reduction of permeability [2,3]. When SAP particles were
added to engineered cementitious composites (ECC), the tensile
strain capacity and toughness of composites were improved [4].
