The performance effect of PEG-silica fume as shape-stabilized phase change materials on mechanical and thermal properties of lightweight concrete panels
Source abstract
Abstract
Sustainable construction is of paramount importance and one of the methods is deployment of phase change materials (PCMs) in construction materials due to their large latent heat capacity. This study aims at investigating the mechanical and thermal properties of non-structural lightweight concrete incorporating shape-stabilized phase change materials (SSPCMs). Toward this purpose, silica fume and polyethylene glycol 600 (PEG 600) composite was prepared with direct absorption method and no leakage was observed. Wallboards with two thicknesses including 10 % and 18 % SSPCM and macroencapsulated PCM layers were built and tested under two ambient weather conditions. Results stated that the application of SSPCM in specimens would reduce the inner-side temperature of wallboards to a great extent and the panels with less thickness had a better thermal performance. Regarding mechanical properties, tensile and compressive strength of concrete at early ages decreased by the growth of SSPCM content, while this reduction was compensated by the passage of time.
