Experimental evaluation of cement mortars with phase change material incorporated via lightweight expanded clay aggregate

AbstractObjective erimental evaluation on cement mortars with phase change material (PCM) incorporated via lightweight aggregate (LWA) is reported. als and methods groups of LWA mortars were produced: one with pre-soaked LWA and the others with PCM-filled LWA combining two different impregnation processes and PCM dosages of 50, 75 and 100 kg/m3 corresponding to the LWA contents of 242, 354 and 481 kg/m3, respectively. Mechanical and thermophysical properties were evaluated. s sults showed that high thermal inertia and low mass are compatible in PCM-filled LWA mortars and that the thermal response increases with the PCM to a certain limit and then decrease.
