Carbide lime and industrial hydrated lime characterization
Powder Technology, 2009Abstract This paper focuses on the characterization of carbide lime (CL) – a by-product of acetylene production, composed mainly of calcium hydroxide with minor parts of carbonate – and compares its features to those of “dry” hydrated lime (HL) commonly used as a building material.

Metakaolin—lime hydration products
Thermochimica Acta, 1984Abstract Four mixtures were prepared of weight ratios 80:20, 70:30, 60:40 and 50:50 of china kaolin/pure Ca(OH) 2 . Each mix was activated for 2 h at 800°C and then paste hydrated at room temperature and 100% RH for up to 28 days. The hydration products were studied by XRD as well as DTA and TG techniques.

Abstract The hydration of soda-lime glass is studied using resonant nuclear reactions to measure the hydrogen and sodium profiles of hydrated glasses. The rate of growth of the surface layer of hydrated glass is initially proportional to the square root of time as is characteristic of diffusion controlled processes.

AbstractA problem has occurred with hydrated lime accelerating the hardening of gypsum plaster retarded to an initial set of about 5 h. Acceleration was so severe that application by trowel was very difficult or even impossible. A sample of such lime and two samples of purified calcium hydroxide have been studied by techniques developed in this ...

Environment-friendly lime paints were prepared from 38 wt% slurries of hydrated lime (Ca(OH)2) and hydrated light burned dolomite (Ca(OH)2·Mg(OH)2). These materials and the resulting paints’ antibacterial and antimold properties were investigated. The hydrated lime used in this study contained 97 wt% Ca(OH)2, which implies a 71.85 wt% equivalence of ...

Hydration characteristics of metakaolin—lime—gypsum
Thermochimica Acta, 1985Abstract The hydration characteristics of some metakaolin—lime—gypsum mixtures were studied by the determination of their hydration products using XRD as well as DTA techniques. The effect of the phase constituents on the compressive strength of the hardened pastes was also investigated.
