Expansion and shrinkage of lightweight vermiculite material at high temperatures [PDF]

Ceramics International, 2023
Vermiculite materials are widely used as insulation material in the industry, fire protection systems, and fire stoves. The high dimensional stability of vermiculite boards ensures that thermal runways in the insulation lining are avoided.

Incorporation of expanded vermiculite lightweight aggregate in cement mortar

Construction and Building Materials, 2018
This investigation presents an evaluation of the properties of cement mortars containing expanded vermiculite as partial sand replacement. When the expanded vermiculite was included at 30% and 60% replacement levels, the flow diameter was higher compared

Dehydration and rehydration of vermiculites: II. Phlogopitic Ca-vermiculite

Clay Minerals, 1994
AbstractDehydration and rehydration of a phlogopitic Ca-vermiculite were studied by thermoanalysis (TG, DSC) and by in situ X-ray powder diffractometry. A detailed analysis of the relationship between temperature and state of hydration of the vermiculite close to equilibrium at atmospheric pressure was rendered possible by use of low heating rates in ...

Thermal study of vermiculites and mica-vermiculite interstratifications

Journal of Thermal Analysis, 1993
Simultaneous DTA-TG has been carried out on a set of natural vermiculite samples. Based on their dehydration behaviour the samples can be divided in two groups: (a) those with DTA endothermic peak temperatures at 140°–150°C and 240°–270°C (pure vermiculties) and (b) those with peak temperatures at 95°–115°C (vermiculite with mica or mica-vermiculite ...

Evolution of Benzylammonium-Vermiculite and Ornithine-Vermiculite Intercalates

Clays and Clay Minerals, 1996
AbstractThis report consists of a study of l-ornithine hydrochloride-vermiculite and of benzylammonium hydrochloride-vermiculite complex. The evolution of these organo-vermiculite structures upon heating is studied by X-ray diffraction (XRD) as well as infrared spectroscopy.After heating vermiculite saturated with 1-ornithine cations, it shows ...
