Kovalyk I. Design of foamgypsum with specified properties

Object of research - foam, foamgypsum mixture, gypsum stone, foamgypsum based on gypsum binders with high dispersion and composite binders; goal - to develop the experiment-calculated method of foamgypsum optimal composition designing with specified indicators and to determine the means to improve its properties; methods - methods of mathematical experiment planning, methods of mathematical statistics, building physics and mechanics methods; results - the experiment-calculated methods of foam composition, foamgypsum mixture, gypsum stone, foamgypsum with it specified indicators have been developed; the obtained mathematical models enable to determinate the effect of specified indicators influence on the foamgypsum properties and its constituent components; the means to improve the foamgypsum properties using gypsum binders with high dispersion, composite binders, additional use of polymer fiber have been determined; novelty - the new experiment-calculated methodology of optimal foamgypsum composition designing with its specified indicators have been developed; based on theoretical analysis, the new integrating mathematical dependencies are obtained for material that is being considered; the effect of influence and interaction of separate structural and technological factors on the foamgypsum properties have been established; the possibility of foamgypsum quality indicators improvement by means of foamgypsum matrix component strengthening and modification of its structure; implementation - the results of work were implemented in the conditions of a pilot-industrial production; in the study process.
