The influence of superabsorbent polymers on the microstructural features and mechanical properties of cementitious mortars subjected to freezing and thawing conditions

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The paper forms a part of a larger study focused on the effect of two different superabsorbent polymers (SAP) on the performance of cementitious mortars subjected to omnidirectional freezing and thawing. Microstructural alterations due to exposure of up to 360 freezing and thawing cycles are documented on polymer modified cement mortars of varied maturity. The results yielded by the Mercury Intrusion Porosimetry and the Scanning Electron Microscopy are used to assess the alterations due to freezing and thawing when compared against corresponding samples cured in laboratory conditions.
