METHOD FOR PREPARATION OF MOLDABLE FILLED COMPOSITION Russian patent published in 1994 - IPC

FIELD: materials testing. SUBSTANCE: materials are tested for granulometric composition and fractions are used with grain size d₁, d₂...d_n which satisfy the condition d₂/d₁≅ d₃/d₂≅ ...≅ d_n/d_n-1≅ 0.063. Next step involves determining void-material ratio of fraction, calculating volume coefficients of grain divergence by interlayer of binder and consumption of components for preparation of composition. Following procedure involves dispersing fraction V_n with grain size d_n in binder V_св and using dispersion V_n+V_св for matching with fractions having larger grains in a sequence of V_n-1...V₂, V₁. After each matching the components are mixed. EFFECT: higher efficiency.
