physical-mechanical properties

In this paper prescriptions of dry building mixes for industrial floors were developed. Main indicators for such material are enough spreadability of fresh mixture during certain period of time, needed for its enclosing, high early strength, minimal deformation of hardened material. Technology of industrial floors construction in buildings with high loading is showed. Investigation of quartz sand with different granulometry on physical and mechanical properties of dry building mix for industrial floors is conducted.

Possibility of fabrication by the method of extrusion of composite on the basis of polypropylene and discrete filler in the form of the grinded fabric is studied. Influence on physical-mechanical properties and water absorption of obtained materials for the fillers of various chemical nature - fabrics on the basis of synthetic or/and natural fibers, their filling degree in polypropylene, as well as dependences of these properties on pre-award dressing of filler is estimated.
