Abstract:
The adoption of high frequency vibrators for placing concrete has been more rapid than the progress in acquiring basic information on such factors as frequency, amplitude, size of vibrator, type of vi-brator, period and method of application and others. In this preliminary recommended practice for vibra-tion, man of the requirements are based on the well estab ished fact and principles of concrete making. Items covered include: type of vibrator, number and capacity, forms, procedure, and adjustment of mix, vibrate-effects of vibration.
