Three 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. The results 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.engCement mortarLightweight aggregateExpanded clay aggregatePhase change materialThermal conductivityCompressive strengthFlexural strengthDensityjournal article10.1016/j.conbuildmat.2014.04.027
