To issue of studying mechanism of increasing strength of porous ceramic crock

Abstract

In our country at the modern stage of the development of constructional industry the necessity arises in qualitative ceramic wall materials. The use of this items provides durability, comfort and architectural expressiveness for constructions. In connection with what is an acute problem of use of “low-grade” clay raw material for production of high-quality wall ceramic products. The solution of problem is to activate clay raw materials in various ways. One of relatively simple, effective and economically expedient methods of the activation of clay raw material is mechanical activation. It is used to improve the quality of dense metamorphisized clay raw materials. But it is not enough, therefore it is offered to hold extra chemical activation by adding chemical additives in raw mixtures. The purpose of present research is to study mechanism of increasing the strength of the ceramic crock affected by the fluxing additive, imputed in raw mixtures proportion based on medium-plastic clay raw materials. To achieve the given purpose, it is necessary to solve the following tasks: a) to investigate influence of fluxing additives on rheological raw mix behavior; b) to study modification mechanism of changing the properties of ceramic crock by adding fluxing additive into the raw mixtures.
