| Title of the article | Dry mixes based on composite gypsum binders |
| Abstract. | The compositions of the dry plaster mixtures based on water-resistant gypsum binder from the composite content were 60 % by weight milled with industrial waste. The obtained dry plaster mixture on its physical-mechanical characteristics meets the regulatory requirements, and resistance to water and techno-economic characteristics superior industrially produced analogues on the basis of gypsum binders. Designed plaster dry mix can be used for levelling and plastering surfaces when carrying out internal works in dry, normal operating mode and in external works subject to protection from prolonged constant moisture and the influence on basic physical and mechanical properties of dry plaster mixtures of oxides of various molecular weights, as well as some air entraining additives. It is established that the efficiency of oxides as water-retaining additives in the composition of the dry plaster mixtures depends on their molecular weight. Increasing the molecular weight of the additive from 400 to 4?106 increases water-holding capacity of the mortar mixtures with 92 to 98 %, the adhesion strength of mortars with basis from 0,3 to 0,6 MPa without compromising the compressive strength and bending. |
