AB  - The mean ionic activity coefficients of NaCl in a ternary system {yNaCl+(1-y) Na_2 HPO_4 }(aq)were determined using electromotive force measurements (EMF) at T = 298.15 K. For EMF measurements, a cell of the type Na–ISE〖NaCl(m〗_NaCl), Na_2 HPO_4 〖(m〗_(KH_2 PO_4 ))AgAgCl  was employed with NaCl ionic strength fractions y = (0.3012; 0.5011; 0.7706) in the range of total ionic strength of the solution I = (0.0701 – 0.9315) mol·kg-1. The Extended Pitzer model was used to analyze experimental data for the mixed electrolyte solution, and good agreement between experimental and calculated values of thermodynamic properties was found with a standard deviation of the fit of 10-3 order.

AB  - The thermodynamic properties of the mixed electrolyte solutions are conveniently described in terms of excess quantities. The excess Gibbs energy of mixing, presents the difference between the excess free energy of a mixed electrolyte solution and free energies of the individual binary electrolyte solutions at the same temperature, pressure and total ionic strength. In this paper the excess Gibbs energy of mixing is calculated for series of mixed electrolyte solutions and possible pairs, triplets, quads or even higher order multiplets were discussed in respect to Scatchard’s mixing parameter values.

AB  - The present paper investigated the influence of mechanical activation of fly ash and various parameters, such as curing temperature and concentration of foaming agent (Al powder), on physical-mechanical characteristics of lightweight geopolymers. Prior to alkali activation, fly ash was mechanically activated in a high energy planetary ball mill. Lightweight geopolymers were obtained by mixing the mechanically activated fly ash with various amounts of Al powder and sodium silicate solution (SiO2/Na2O mass ratio of 1.5). Geopolymer paste samples were cured covered in plastic either at room temperature for 28 days or at elevated temperature (95 oC) for 4 hours. It was observed that the mechanical activation of fly ash resulted in a drastic increase of geopolymer compressive strength regardless of curing conditions, preserving the lightweight properties at the same time. The lightweight geopolymers based on mechanically activated fly ash might be used both in constructive and insulating applications.
