Dielectric Hardening Method of Sandmixes Containing Hydrated Sodium Silicate
M. Stachowicz, K. Granat, D. Nowak. Wroclaw University of Technology, Wroclav, Poland The subjec t-matter of the paper c overs a v ery topical problem of possible r estriction of shor tcomings like poor knocking-out properties of castings and hard reclaimability of this type sandmixes by proper selecting their components and using innovative microwave heating. It was proved that the sandmixes s...
متن کاملEmpirical force fields for complex hydrated calcio-silicate layered materials.
The use of empirical force fields is now a standard approach in predicting the properties of hydrated oxides which are omnipresent in both natural and engineering applications. Transferability of force fields to analogous hydrated oxides without rigorous investigations may result in misleading property predictions. Herein, we focus on two common empirical force fields, the simple point charge C...
متن کاملMolecular silicate and aluminate species in anhydrous and hydrated cements.
The compositions and molecular structures of anhydrous and hydrated cements are established by using advanced solid-state nuclear magnetic resonance (NMR) spectroscopy methods to distinguish among different molecular species and changes that occur as a result of cement hydration and setting. One- and two-dimensional (2D) solid-state (29)Si and (27)Al magic-angle spinning NMR methodologies, incl...
متن کاملModel for the interpretation of nuclear magnetic resonance relaxometry of hydrated porous silicate materials.
Nuclear magnetic resonance (NMR) relaxation experimentation is an effective technique for probing the dynamics of proton spins in porous media, but interpretation requires the application of appropriate spin-diffusion models. Molecular dynamics (MD) simulations of porous silicate-based systems containing a quasi-two-dimensional water-filled pore are presented. The MD simulations suggest that th...
متن کاملFractionation and solubility of cadmium in paddy soils amended with porous hydrated calcium silicate.
Previous studies have shown that porous hydrated calcium silicate (PS) is very effective in decreasing cadmium (Cd) content in brown rice. However, it is unclear whether the PS influences cadmium transformation in soil. The present study examined the effect of PS on pH, cadmium transformation and cadmium solubility in Andosol and Alluvial soil, and also compared its effects with CaCO3, acidic p...
