Cement & Mortars - Consistency Meter

 

Consistency Meter 

Consistency measurement of fresh mortar is an important process to ensure that the mortar has the correct workability and quality. 

Here are some methods and standards that are used: 

Flow Table (Shaking Table) Method: 

This method involves using a flow table to measure how much the mortar spreads when subjected to vibration.
The mortar is placed in a conical mold on the flow table, and after a specified vibration time, the diameter of the spread mortar is measured. 

Drop Table Method: 

In this method, the mortar is placed in a conical mold on a drop table.
The table is raised and dropped a specified number of times, and the diameter of the spread mortar is measured to determine the consistency. 

Standards: 

EN 1015-3, which specifies how the consistency of fresh mortar shall be determined using the flow table method.
ASTM C230 – Standard specification for use of the flow table (drop table) method.
