Abstract

PURPOSE:To make the gradient of amplitude displacement larger with respect to a change in a water-cement ratio by vibrating sensing plates at the driving frequency coinciding with the natural frequency of concrete which has not ser yet. CONSTITUTION:The output of an oscillator 8 which oscillates the frequency equal to the natural frequency of concrete which has not set yet is set at the output corresponding to the consistency of the concrete by an ammeter 10 at an amplifier 9, and drives an electromagnetic driving source 6. On the other hand, sensing plates 5 of a biconvex lens shape of which the top ends of legs 4 are fixed to a pair of leaf springs 3 mounted to both sides of a body 1 of a measuring machine and which are fixed to the leading ends of the legs 4 are excited by the source 6 and vibrate to the right and left. The signals from a pickup 7 are inputted via an amplifier 11 to an indicator 12, by which the rates of vibration displacements are displayed. Thereby, the gradient of amplitude displacements is increased and the water-cement ratio is measured accurately.
