Rapid urbanization, Integration of urban and rural areas has brought many negative effects for ecology, living environment and sustainable development, Land for Construction-oriented system of traditi...
The expansivity of a silicate melt in the relaxed liquid state was obtained by direct dilatometric measurement for the first time. During the measurement, the liquid sample resides within a metal co...

Thestructure oflizardite-l Tfrom MonteFico,Elba,wasrefined in spacegroupP31m usingneutron diffractiondata, measuredat 8, 150,and 294K,and full-profile Rietveld refinement techniques. Thelattice param...
The cell parameters of deuterated gypsum have been extracted from Rietveld anal-ysis of powder neutron diffraction data within the temperature range 4.2-320 K.The thermal expansion of gypsum is highly...
The temperature dependence of the lattice parameters of synthetic lawsonite [Ca-A12Si207 (OH)2 .H20], natural zoisite [Ca2A13 Si30'2(OH)], natural clinozoisite [Ca2Al3Si3012(OH)], and synthetic diasp...
Abstract: A process for treating smectite-bearing rock samples that utilizes LR White resin; allows TEM observation of expanded smectite interlayers and therefore preservation of original rock texture...
Suspensions were produced by mixing Na-saturated, Upton montmorillonite with aqueous solutions containing different concentrations of 1,4-dioxane. Each suspension was deposited on a porous ceramic fil...
Abstract: Expansion properties of ten homoionic smectites that differed in amount and location of layer charge were examined by X-ray powder diffraction analysis at various relative humidities, or aft...
The effects of relative humidity (RH) on the expansion of Mg-smectite, equilibrated with low vapor pressure of ethylene glycol (EG), was studied. Four smectite samples were equilibrated with EG vapor ...
Abstract: Treatment of smectite with laurylamine hydrochloride was verified to cause expansion of d(001) which may be retained and observed in ion-milled samples by transmission electron microscopy. T...
To understand and predict the effects of a thermal pulse induced by a radioactive waste repository on clinoptilolite-bearing rocks, the lattice parameters of 6 natural and 3 cation-exchanged (Ca, K, N...
Properties of Vermiculites and Smectites: Expansion and Collapse     Properties  Vermiculites  Smectites  Expansion  Collapse       font style='font-size:12px;'> 2012/2/21
Samples of smectites and vermiculites were evaluated to (1) determine the effects of source and amount of charge, (2) determine if a continuum of properties exists, and (3) improve the basis for diffe...
Properties of Vermiculites and Smectites: Expansion and Collapse     Vermiculites  Smectites  Expansion  Collapse       font style='font-size:12px;'> 2011/11/16
Recent reports have suggested that the smectites and vermiculites exhibit a continuum in properties. This, in association with differences in methods and criteria between investigators, suggests the n...
