| Abstract. | In work such important characteristic of powdery materials as fluidity (or flowability) is investigated. It is complex rheological characteristic depending on density, a fractional structure, a form of particles and a condition of their surface. Forces of a friction and coupling of particles among themselves, in powder materials science called by the general term an autogeziya are defining. It is obvious that mineral knitting and their applications for manufacturing of materials and products mobility (fluidity) of powdery products plays a paramount role production technologies at their transportation, dispensing (the expiration from account bunkers), during the filling of silos, sedimentation in cyclones and filters. Data on mobility of these powders are necessary at design and designing capacitor (including warehouse) the equipment. We studied properties of powders of a cement, quartz, limestone and on their basis of it is thin the groundcements and cements of low water requirement. Change of such characteristics of powders as relative density, diameter «spread» (by D, cm) and a corner of a natural slope (ц, a hail) depending on their specific surface and the content of S-3 supersoftener is defined. |
