Simulation studies on metastable phase equilibria in the aqueous ternary systems (NaCl-MgCl

Tianlong DENG, Baojun ZHANG, Dongchan LI, Yafei GUO

Frontiers of Chemical Science and Engineering 2009, Volume 3, Issue 2,   Pages 172-175 doi: 10.1007/s11705-009-0048-1

Abstract: The solubilities and densities of the aqueous metastable ternary systems (NaCl-MgCl -H O) and (KCl-MgCl -H O) at 308.15 K were determined by the isothermal evaporation method. On the basis of the experimental results, the phase diagrams for those systems were plotted. It was found that the former system belongs to the hydrate-I type with one invariant point of (NaCl+ MgCl ?6H O), two univariant curves, and two crystallization regions corresponding to halite (NaCl) and bischofite (MgCl ·6H O); and the latter system belongs to the type of incongruent-double salts with two invariant points of (KCl+ KCl·MgCl ·6H O) and (MgCl ·6H O+ KCl·MgCl ·6H O), three univariant curves, and three crystallization regions corresponding to potassium chloride (KCl), carnallite (KCl·MgCl ·6H O) and bischofite (MgCl ·6H O). No solid solutions were found in both systems.

Regeneration of vernacular architecture: new rammed earth houses on the upper reaches of the Yangtze River

Jiaping LIU, Rongrong HU, Liu YANG, Runshan WANG,

Frontiers in Energy 2010, Volume 4, Issue 1,   Pages 93-99 doi: 10.1007/s11708-010-0002-4

Abstract: In rural areas of western China, most of the vernacular architectures are made of earth. In the process of urbanization, few residents like to build their houses with earth because the old traditional earth house cannot meet their requirement for higher standard of living. As a result, much more energy will be consumed if industrial building materials are used instead of earth. The regeneration of the traditional earth house, therefore, becomes a challenge in new village construction. This paper briefly describes a project about creating a new prototype of earth house for the migrants along the upper reaches of the Yangtze River to shed light on finding an appropriate approach for regenerating the traditional earth houses with the concept of low-energy housing. It includes an investigation of the traditional earth house and the environment condition of the new settlement, the new house design process, and the quantitative evaluation of the living quality of the new house.
