Title of the articleThe influence of addition of mechanically activated mineral fillers on properties of composite gypsum binders
Abstract.Problem statement. The purpose of this work was to study the influence of the method of grinding quartz and carbonate fillers in a ball mill and in an electro-mass classifier with intensive mechanical activation of the surface of the filler particles on the efficiency of their introduction into the composition of composite gypsum binders. Results. It was found that due to the effect of mechanochemical activation of the surface of the particles of quartz filler when grinding in an electromassifier to an optimal specific surface of 500 m2/kg with the introduction of 5 % by weight of ground additives in the composition of composite gypsum binders 15 % increase in strength indicators is achieved compared to compositions without the introduction of filler additives. With the introduction of additives in an amount of up to 15 % by weight, the strength and water resistance are maintained at the level of control samples. Compared with the introduction of a similar amount of quartz filler, milled in a ball mill, a maximum increase in strength indicators by 10% is achieved. When grinding carbonate fillers in an electric mass classifier compared to grinding in a ball mill, there is a slight increase in the strength of the binder. Conclusions. The significance of the results for the construction industry lies in the fact that the expediency of the use of electro-mass classifier in the preparation of additives quartz filler, introduced into the composition of composite gypsum binders.
Keywords.composite gypsum binder, mineral filler, mechanochemical activation, gypum-scement-pozzolanic composition, artificial stone, water resistance.
