In light of the urgent demand for enhanced temperature control within
the realm of construction and building applications, this research presents an
innovative shape-stabilized phase change material (PCM). Effective thermal
energy storage has been made possible by combining myristic acid (MA) and
lauric acid (LA) with sepiolite in cement mortars. These innovative
PCM-incorporated mortars present promising solutions for reducing daytime
cooling loads and enhancing thermal comfort in buildings. The research
thoroughly examines the influence of Sepiolite infused with PCM on the thermoregulatory
efficiency of cement mortar in specially designed test chambers simulating real
ambient conditions. The research findings underscore the material's remarkable
thermal stability, reliability, and capacity to efficiently absorb and release
substantial latent heat. The study discloses the latent heat storage properties
of the SEP/LA-MA composite, with 79.01 J/g absorbed during melting and 78.67
J/g released during solidification. Thermal durability, evaluated through 500
consecutive cycles, demonstrates consistent phase transition characteristics.
Post-cycling, the composite maintains an impressive 78.68 J/g latent heat of
fusion, retaining 99.5% of its original capacity. The TGA results emphasize the
exceptional thermal stability of Sepiolite, LA-MA, and the composite,
underscoring their ability to withstand typical operating conditions
effectively. The introduction of these innovative cement-based composites equipped
with shape-stable PCM holds significant potential for various building
components. This contribution is aimed at elevating the energy efficiency and
comfort levels of buildings.
