RESONANCE INSTALLATION FOR DETERMINATION OF STRUCTURIZATION KINETICS OF CEMENT-TYPE BINDERS

摘要

FIELD: acoustic measurements. SUBSTANCE: installation has generator of audio-frequency oscillations, exciter and receiver of oscillations, resonance indicator, tray mounted in suspensions secured to exciter and receiver of oscillations. Novelty is in that installation is provided with tray having the antiadhesive coating of internal surface, mostly from the row of saturated hydrocarbons or substances containing them (waxes principally). Tray is made as half-cylinder with cylinder radius-to-tray length relation of 1: (20-25), Coating is used at a rate of 120-150 g/sq.m of tray internal surface. EFFECT: more effective determination of structurization kinetics. 4 cl, 4 dwg
