| Title of the article | The influence of thermally activated clay additives on the properties of composite gypsum binder |
| Abstract. | Finding cheap and affordable local effective pozzolanic additives is an actual problem, the solution of which allows to increase the economic and environmental attractiveness of the production and use of cement and gypsum binders. The presence of thermally treated clays in the composition of mineral binders, mortars and concretes on their basis is noted in the executed researches of ancient buildings and structures. In recent years researchers in several countries performed works aimed at the substantiation of the possibility of use of affordable and accessible to local thermally activated clays as active mineral additives in the production of knitting. The studies performed in the present work show a fairly high efficiency of application of the thermally activated clay as the active mineral additives for production of composite gypsum binders. Introduction to the composition of the composite gypsum binder as the active mineral additives thermally activated clays in the required quantities at specific surfaces 200 and 500 m2/kg was respectively increased the compressive strength by 5 and 13 %; increase of softening coefficient up to 0,9 and 0,94 (water-resistant binders) compared with control samples. |
