| Title of the article | Gypsum binder with additives of a haydite dust |
| Abstract. | In this work dependences of the main properties of gypsum binder on the contents, mineral structure and a subtlety of a grinding of additives of a haydite dust are received. It is established that introduction of additives of a haydite dust of various mineral structure and dispersion in quantity to 20-30 % doesn't cause essential decrease in the physical-technical indicators of gypsum binder. This phenomenon is explained by the effect of the steric constraint. It is established that decrease in the contents of a haydite dust the undehydrate clay with 14,1 to 9,5 % leads to increase of efficiency of a haydite dust as an additive in gypsum binder. The carried-out researches allowed to develop structures economic gypsum binder with the contents to 30 % of a ground haydite dust at its optimum specific surface of 500 m2/kg. Thus essential decrease in physical-technical indicators of the gypsum binder doesn't occur. |
