EFFECT OF SUPERABSORBENT PARTICLE SIZE ON RHEOLOGY AND MECHANICAL PERFORMANCE OF CEMENT MORTARS
Original language description
The risk of crack propagation and autogenous shrinkage pose a significant weakness for concrete structures and substantially limits its lifespan. To overbridge related issues, the smart superabsorbent polymers (SAP) can be utilized to mitigate autogenous shrinkage and promote self-healing ability. However, incorporation of highly swelling particles struggles with the workability of the fresh mixture and thus final mechanical performance. Within this paper, the effect of SAP particle size is studied and correlated with the results of flow table test to propose an optimal relationship between the amount of SAP dosage, water/cement ratio and mechanical properties in the hardened state. The reference cement mortar mixture is modified by 0.25, 0.5 and 0.75 wt.% admixture of different 3 grades of SAPs thus the fresh mixture workability, basic material properties, compressive and flexural strength parameters are determined. The obtained results provide guidelines for the efficient design of SAP modified cement mortars mixtures with desired functional properties.
