Tertychnyi A. Modified solutions of increased adhesive strength and crack resistance of multifunctional purposes

The object of research – modified cement mortars for arrangement of floor elements and restoration of the destroyed sites of mortar surfaces; aim – improving the quality of cement mortars for various purposes, in particular adhesive strength and crack resistance by modifying mixtures with polydisperse silica-containing fillers of different genesis and different structure and superplasticizers, taking into account different methods of their preparation; methods – experimental research, method of planned experiment, computer modeling; results – theoretically substantiated and experimentally confirmed the possibility of improving the quality of modified solutions under the influence of polydisperse, silica-containing fillers, superplasticizers of different types and methods of preparation of mixtures; implemented – at the CBE "Montagespecconstr" in Odessa, as well as in the educational process at the Odessa State Academy of Civil Engineering and Architecture.
