In this experimental work, splitting tensile strength on composite specimen of polymer cement mortar (PCM)-concrete were conducted under various environmental conditions. To investigate the behaviour of polymers in PCM, gel permeation chromatography (GPC) and differential scanning calorimeter (DSC) tests were performed on extracted polymers. Reduction in split tensile strength was observed under all conditions. GPC results showed the degradation in polymers and DSC analysis showed insignificant variation of polymer properties under given exposure conditions.
