| Title of the article | Pozzolanic activity of a haydite dust and its dependence on a specific surface |
| Abstract. | Results of researches influence of a specific surface and granulometric structure of a ground haydite dust of a certain chemical and mineral composition on its pozzolanic activity, and also the main physical and technical properties of an artificial stone on the basis of the composite gypsumlimehaudite binder are presented. It is established that with increase in a specific surface of a haydite dust from 250 to 800 sq.m/kg increase of its pozzolanic activity for 42 % is observed that according to data of the analysis of granulometric structure of a haydite dust is connected with growth of its dispersion. The dependences characterizing influence of a specific surface and the maintenance of an additive of a ground haydite dust on the main physics and technology properties of a composite gypsumlimehaudite binder and artificial stone on its basis are received. It is established that introduction of 20-25 % of an additive of a ground haydite dust with a specific surface of 500 sq.m/kg together with 5 % of lime in gypsum binder provides increase of coefficient of a softening of an artificial stone from 0,33 to 0,66-0,64 that corresponds to indicators for composite gypsum binders to the increased water resistance. |
