This research is primarily aimed at exploring possibilities of
storing an organic phase change material (PCM) in a composite.
Phase change materials have previously been successfully stored in
gypsum wallboard. During the present research work certain
aggregate and filler materials were selected after detailed
laboratory tests as possible constituents for the proposed
composite. Absorption of PCM and retention thererof in materials-
like expanded shale, volcanic rock,
activated charcoal, gypsum and vermiculite , etc. was determined.
Efforts were made to prepare polymer concrete composites from pre- PCM impregnated aggregates, fillers and polyester resin but the results were not promising. Composite specimens were then prepared using coarse aggregates,
gypsum, sand, cement, sawdust, vermiculite etc. and water. Several mix compositions using different proportions of these materials were prepared. The gypsum coftr(*ete specimens so prepared were cured, dried and impregnated with PCM. The absorption capacities of PCM 1n the specimens were determined and compressive strength tests, DSC analysis, infrared spectroscopy and thermal conductivity tests were performed.
