Title: Effects of Drying Conditions, Phase Transformations and Carbonation Reactions on Measurements

Abstract

The sorption isotherm is one of the basic material properties used in hygrothermal modeling of building envelope performance. Measurement of this property is deceptively simple. Specimens are first dried and then exposed to a series of higher relative humidities to develop a curve of moisture content versus relative humidity at constant temperature. This paper discusses some confounding effects that we have observed while performing measurements on a number of common building materials. Materials studied included gypsum products, wood and wood products, and cementitious materials.

  • The paper presents the results of an experimental investigation on the effects of drying conditions, specimen size and presence of plasticizing admixture on the development of shrinkage strains. The measurements are taken in a harsh (50 deg. C and 5% R.H.) and a moderate environment (28 deg. C and 50% R.H.). The results include strain development at various levels of cross sections of concrete prisms. The drying conditions are found to be the dominant parameter affecting the shrinkage strain development particularly in specimens of smaller sizes. The effect of plasticizing admixture on shrinkage strains is negligible.
  • Bromine atoms produced via the /sup 76/Kr(EC electron-capture)/sup 76/Br and /sup 77/Kr(..beta../sup +//EC)/sup 77/Br transformations were reacted with simple benzenoid compounds in the liquid phase. For both /sup 76/Kr and /sup 77/Kr, bromodeprotonation resulted in a reactivity constant rho/sup +/ approx. -0.6, with higher yields for /sup 76/Br. Whereas bromodeprotonation was hypothesized to occur via formation of a product-determining sigma-complex by radical bromine species, ipso substitution was described in terms of a two-step addition-elimination mechanism in which bond breakage is product determining. While radical bromine species are probably involved in substituent displacements from monosubstituted arenes, polysubstituted aromatic compounds activated tomore » nucleophilic attack were shown to involve an additional nucleophilic reaction pathway. 73 references, 10 figures, 12 tables.« less

  • Hydrothermal treatment of albite, labradorite, and orthoclase in mixtures with dolomite revealed that at P/sub H/sub 2/O/ = 1000 kg/cm/sup 2/ and a residence time of 24 to 72 hr at T = 200 to 400/sup 0/C, mainly calcite and trioctahedral layered silicates are formed. At 300 to 500/sup 0/ the following formation sequence was observed: montmorillonite ..-->.. (Mg, Al) serpentine ..-->.. chlorite from plagioclases and montmorillonite ..-->.. a disordered mixed-layer phase of the mica-montmorillonite type ..-->.. phlogopite from orthoclase. At 500 to 600/sup 0/ there is a tendency for formation of framework aluminosilicates (nepheline, kalsilite) at high Na andmore » K concentrations in the initial mixtures, and nesosilicates (monticellite, forsterite) at high Ca and Mg concentrations. It is shown that as the residence time is increased synthetic and natural montmorillonites with Al/sup IV/ are not converted to ordered 1:1 mixed-layer phases, in contrast to those observed in systems with kaolinite. This is probably due to the statistically uniform distribution of Al in a structure of beidellite-type montmorillonites synthesized from feldspars, whereas beidellites with polar distribution of Al/sup IV/ over the (Si, Al-O) tetrahedral networks are apparently developed from kaolinite. When the albite structure is converted to the pyroxene structure, a considerable part of the tetrahedra is inherited by the latter; this follows from retention of the values of the chemical shift and quadrupole splitting typical of tetrahedral /sup 57/Fe(III). The experimental data can be used to reconstruct the primary mineral composition of metamorphic pararocks.« less
  • We present the results of an experimental investigation of the {gamma}-a martensitic transformation upon cyclic cooling of structurally unstable steel, taking into account such factors as time, preliminary deformation, and sustained loading of the material. We have established that the thermomechanical conditioning of the samples intensifies the phase transformation in the elastic and plastic regions. As a result of a comparative analysis of the loading of the material according to different programs, we have obtained quantitative and qualitative assessments of the martensite formation due to each of the considered factors.
