Thermal insulation materials based on expanded vermiculite and foamed liquid glass

NOVYE OGNEUPORY (NEW REFRACTORIES), 2020
This article examines the properties of thermal insulation materials made on the basis of expanded vermiculite and a liquid-glass binder obtained by foaming with a gas-forming agent (foaming agent) and volume-cured by chemical reaction with sodium fluorosilicate.

Sound absorption study of raw and expanded particulate vermiculites

Applied Physics A, 2016
Expanded and raw vermiculite minerals were studied for their ability to absorb sound. Phase and structural characterization of the investigated vermiculites was found similar for both types, while morphology and surface properties vary. Sound waves reflect in wedge-like structure and get minimized, and later are absorbed totally.

SOME PHYSICAL PROPERTIES OF LIGHTWEIGHT MORTARS WITH EXPANDED VERMICULITE

STEPGRAD XVI (2024)
<p class="ABSTRACT">Expanded vermiculite was added to the cement-lime mortar at 10%, 20% and 30%, which reduced the density of the hardened mortar (HM) without expanded vermiculite (EV) by an average of 8,3% for the HM with 10% EV, 14,7% for the HM with 20% EV and 24,2% for the HM with 30% EV.

Developments of the UralNIIstrom Institute in the field of technologies and equipment for enrichment of vermiculite ores and production of expanded vermiculite

Construction Materials
Vermiculite deposits are a heterogeneous array of micaceous minerals of varying degrees of hydration with a significant number of host rocks.The development of technology and equipment for both the enrichment of vermiculite ores and for the swelling of vermiculite and hydrosludes should be carried out taking into account their mineralogical features ...
