  • The moisture buffering performance of plasters when

    2021-2-1 · When sinusoidal RH variations were applied, the adsorption capacity dropped by 46% for clay and 60% for gypsum. The desorption is less effected by the change of the humidity function, as it was reduced only of the 14% for clay and 17% for gypsum.

    volumometry. The technique involves applying a pore pressure sinusoidal wave in one end of the sample while monitoring the attenuation and phase shift of the wave at the other end, from which the permeability and storage capacity of the sample is calculated. The advantage over other techniques is that it allows continuous monitoring

  • The moisture buffering performance of plasters when

    This paper investigates the response of clay and gypsum plasters to quasi sinusoidal and simultaneous humidity and temperature functions. It was experimentally shown that the relative humidity influences the amount of water vapour adsorbed and desorbed by the materials, while temperature impacts the rate and the time lag response of clay and gypsum to the indoor

  • Thermal characteristics of shape-stabilized phase

    2010-8-1 · This is due to the fact that when the sinusoidal temperature wave propagates from the outside to the inner side of the SSPCM wall, the SSPCM is melted or solidified within a narrow temperature range. Therefore, the inner surface temperature will keep constant at or near the melting temperature until the phase transition ends.

  • Shaking Table Model Test on the Dynamic Response

    2018-8-30 · A pure sinusoidal wave and an actual seismic wave recorded from the Wenchuan-Antaxian earthquake were both used to load the slope model. Both the waves were applied in horizontal X direction. Firstly, sinusoidal waves with frequencies of 5 Hz, 7 Hz, 9 Hz, 11 Hz, 13 Hz and 15 Hz were loaded for the model; the amplitudes of all these waves were 0.1 g.

  • Evaluation of structural fatigue properties of metro

    2019-11-1 · Based on determination of dynamic load (see Section 2), the amplitude of experimental sinusoidal wave is equal to 85.21 kN to simplify the complex dynamic wave. The main stress distribution range of railway under single wheelset load is 5 sleepers and the width of the track plate of ballastless track is 2.8 m, so the average stress in theory is σ d = 85.21 4 ×

  • Cyclic and Fatigue Behaviour of Rock Materials:

    2017-10-17 · A sinusoidal signal may be more representative of stress wave generated during rock burst or earthquakes, but linear variations are often simpler to apply (Bagde and Petroš 2005b). Although the maximum stress and period are identical for all signals, the energy provided to the sample as well as the imposed accelerations differs.

    High density gypsum board has, typically, a compressive strength of about 375 psi. The total weight of ten units of high density gypsum board is about 32,640 pounds, and this is the weight supported by the lowermost set of risers. The weights supported by risers which are higher in the stack are, of course, less.
