“…Gypsum-cement-pozzolanic binder (composition: gypsum binder -53.3%, Portland cement -33.3%, active mineral additive -metakaolin 13.4%) was modified with the addition of superplasticizer, modified cellulose ether and redispersible polymer powder [24][25]. We have previously studied the properties of such a modified GCPB with various fibers -glass fiber, basalt, polyamide, and polypropylene fibers [26]. It has been shown that the reinforcement of GCPB with fibers contributes to an increase in strength indicators, increases the water resistance and durability of products.…”

Composite gypsum binders harden quickly, gain strength quickly and have positive environmental properties. Moreover, they are characterized by increased moisture resistance, which significantly expands the field of application of such gypsum materials. Dispersed reinforcement of composite gypsum binders with polypropylene fibers makes it possible to obtain composites characterized by high performance properties. On basis of developed compositions of gypsum-cement-pozzolanic and composite gypsum binders with polymer fibers, gypsum composites have been created, characterized by increased strength, water resistance, frost and corrosion resistance.

“…Problem Statement. Development of dry nanoadditives is important for modification of binders, dry mortars and concretes [1][2][3][4][5][6]. The process of introducing nanosystems (nanoparticles, nanotubes) into the composition of binders is very complex due to their small amounts (from hundredths to thousandths parts of percent), as well as due to their nanometric dimensions [5][6][7][8][9][10][11][12][13][14][15].…”

The article deals with the issue concerning production of a dry nanoadditive. In order to achieve this goal, an aqueous solution of polyvinyl acetate dispersion (PVAD) and nanotubes, or lime slaking nanoparticles is used. As a result of the hydration process heat is released, the polyvinyl acetate emulsion forms particles with nanotubes in their composition. During the study performed an optimal ratio of all components was established: quicklime + PVAD-CNT – 71-73% and 0.01-0.018 CNT; “Megalith” – 21-25%; ammonium salt – 4-6%, as well as the optimal amount of the complex additive, which is in the range of 1-1.5% by weight of calcium sulfate hemihydrate. Later on the resulting nanoadditive can be used to modify binders or other materials
