Viber consistency determination

This method is suitable for the fluidity of dry hard concrete mixture with a slump of less than 10mm. The test method is to put the concrete mixture into the slump cylinder according to a certain method, tamping according to a certain method, and after filling and leveling, lift the slump cylinder vertically upwards, and turn the transparent disc to the concrete circular platform body. On the top surface, turn on the vibrating table and use a stopwatch to count at the same time. When the bottom surface of the disc is covered with grout, the watch stops and the number of seconds read is the Viber consistency of the concrete mixture. This method is suitable for the determination of the consistency of concrete mixtures with the maximum aggregate size not exceeding 40mm and the Viber consistency between 5-30s.

The fluidity of concrete mixture can be divided into four grades according to Weibo consistency, as shown in the following table:
