Introduction of novel kinetic approach to calculation of activation energy and its application to the sinter-crystallization of strontian feldspar
The kinetics, the mechanism and the thermodynamics of activated state of formation of primary strontian feldspar via sinter-crystallization of non-equilibrium melt during the thermal treatment of ceramic body was investigated ...
The determination of the influence of pH value of curing conditions on Portland cement hydration
Water composition during cement hydration can be changed due to migration of ions from the cement matrix to the solution. The storage of various materials together can lead to transfer of various ions and distortion of ...
The formation of feldspar strontian (SrAl2Si2O8) via ceramic route: Reaction mechanism, kinetics and thermodynamics of the process
The reaction mechanism, the equilibrium composition, the temperature range of stability of formed intermediates as well as the kinetics and thermodynamics of activated state during the formation of monoclinic strontium-a ...
The field of solid solutions in ternary system of synthetic apatite-type alkaline earth element-yttrium-silicate oxybritholite phases of the composition: AEE(delta)Y(10-delta)[SiO4](6)O3-0.5 delta, where AEE=Ca, Sr and Ba
(Elsevier Ltd, 2016-01-08)
This contribution deals with the synthesis, properties and investigation of the field of solid solutions formed between the three end-members of apatite-type alkaline earth element-yttrium-silicate oxybritholites with the ...
The influence of barium sulphate and barium carbonate on the Portland cement
(Elsevier Ltd., 2016-08-03)
Shielding of different types of radiation should be studied these days when there is a great development in the field of nuclear science. Barium ions can shield different type of radiation, therefore, by incorporation of ...
The ash from fluidized bed combustion as a donor of sulfates to the Portland clinker
The paper deals with possibilities of using solid residues from fluidized bed combustion of coal, bed and filter ash in the production of composite Portland cements. The ash from fluidized bed combustion contains a high ...
