The Effect of Superabsorbent Polymers on the Microstructure and Self-Healing Properties of Cementitious-Based Composite Materials

Cementitious structures have prevailed worldwide and are expected to exhibit further growth in the future. Nevertheless, cement cracking is an issue that needs be addressed order enhance structure durability sustainability especially when exposed aggressive environments. The purpose of this work was examine impact Superabsorbent Polymers (SAPs) incorporation into cementitious composite materials (mortars) with respect their (hybrid consisting organic core—inorganic shell) evaluate microstructure self-healing properties obtained mortars. applied SAPs were tailored maintain functionality environment. Control mortar/SAPs specimens two different concentrations (1 2% bwoc) molded mechanical determined according EN 196-1, while behavior evaluated via microCT. Compressive strength, a key property for mortars, which often degrades incorporation, work, practically remained intact all specimens. This coherent porosity reduction narrower range pore size distribution as Moreover, mortar-SAPs enhanced up 60% compared control Conclusively, overall cementitious-based optimized.
