FIELD: acoustic measurements. SUBSTANCE: invention can find use while investigating processes of solidification of binding materials, for example cements. Resonance plant to determine kinetics of structure formation of binding materials of type of cements includes acoustic frequency generator, exciter and detector of oscillations, resonance indicator, dish mounted in suspensions attached to exciter and detector of oscillations. Plant is provided with dish having antiadhesion coat of internal surface made from hydrocarbons and substances containing them, mainly waxes. It is fabricated in the form of semicylinder with ratio of radius of cylinder to length of dish 1: (20-25). 120-150 g/sq.m of matter is used for coating of internal surface of dish. EFFECT: increased authenticity of obtained data with expansion of functional capabilities. 3 cl, 4 dwg |
