Web1 nov. 2015 · To the authors’ best knowledge, this hydrophobic expanded perlite has never been investigated for the development of thermal energy storage composites. An uncoated expanded perlite was also used to prepare PCM composite to study the PCM leakage in previously developed form-stable PCM composites. WebLightweight mortars composed from a lime-metakaolin binder or lime-cement binder and expanded perlite filler were prepared and tested. Mortar test samples were firstly cured in a humid atmosphere and subsequently in laboratory ambient conditions. Development of hardening processes was studied by X-ray diffraction and thermal analysis. Web15 jan. 2016 · Perlite is a volcanic glass mineral found extensively in volcanic rock. When perlite ore is treated and heated (over 870 °C) under suitable conditions, it grows up to 20 times its original volume and becomes porous [1]. After this physical transformation, its color turns from gray to white. inglot store tysons
