How to Properly Make Compression Test Grout Cubes

[@syazwanroslee657]

Can I know which standard did you use for the grout testing?

[@donnakatetoledo5771]

We cant avoid human error or inconsistency during the manual tamping. Is there an automatic jigger or tamping procedure that we can use which still aligned with astm c109. Thank you!

[@khaistarahman7225]

This actually is full of errors. Working for a supplier if I ever saw a tech make cubes this way I would not accept any of their results.

Those cubes should be rodded 32 times alternating along the sides after every 4. 2 lifts. Its honestly surprising how many technicians dont know how to do cubes, however cubes and mud balance arent taught on the ACI I and it really should be...

@David M You are absolutely correct in all of this! Glad I'm not only the one who thinks this and sees that it isn't taught on just about a daily basis.
