Abstract: Spatial distribution of superabsorbent polymers (SAP) particles was evaluated using point process statistics. Presence of aggregate particles was treated by thinning points of SAP from a basic process. K function of SAP in the thinned point process was compared with that in actual mortars. SAP in the mortars clustered more than in the thinned process. Aggregate had a certain effect to promote clustering of SAP particles. The clustering tendency in the mortars depended on sizes of SAP particles. Differences in autogenous shrinkage behaviors of the mortars can be related to inhomogeneous supply of internal water from the clustered SAP at early ages.
