| Title of the article | Composite gypsum binder with additives of a lime, a haydite dust and supersofteners |
| Abstract. | The results of studies of the effect of different supersoftener on the properties of the сomposite gypsum binder with lime and expanded haydite dust. The chemical, mineral and particle size distribution and hydraulic activity expanded haydite dust. Found that the haydite dust is activated clay, which includes a number of not dehydrated clay and dehydrated clay minerals with different crystal lattices of the defect level. Established mathematical relations that characterize the effect of the content of additives supersoftener different chemical nature when administered in conjunction with lime and ground expanded haydite dust on basic physical and technical properties of the composite gypsum binder. Developed low-cost composite gypsum binders with the introduction of additives considered supersoftener in an amount of 0,5 to 1 % with 20 % of the expanded haydite dust dispersion of 500 sq. m/kg and 5 % lime plaster provides reception binders with compressive strength of 23 to 25 MPa and softening coefficient from 0,74 to 0,78, which belong to the composite gypsum binders increased water resistance. The resulting composite gypsum binder can be used for plastering, installation and flooring solutions and low marked concrete. |
