Abstract


the objective of this research is to test different variables combinations and show which Poly (cutylene succinate)-based (PBS-based) material OBS material has the best properties to be added as a Bio-phage-change material in concrete matrices. In this experimental study, a novel PBS-based phase change material (PCM) was synthesized to be applied in concrete systems to increase thermal resistance. Box-Behnken design was followed to produce a total of 14 samples with different reaction times, catalyst concentrations, and glycerin concentrations (which acted as additives). All of the samples were able to decrease the regular melting point of PBS from 110ºC to around 68ºC, showing a significant improvement that allows the use of this material to improve the thermal properties of concrete systems.
