Learn How to Properly Complete Mud Balance Test

This TIP is intended to facilitate the process of a Mud Balance test. A Mud Balance test is used to find the specific gravity (SG) for the grout mixture. This is done by comparing the unit weight of the grout mixture to the unit weight of water. Five gallons of water mixed with a typical 94 lb. bag of type II Portland cement will give a specific gravity around 1.84, which typically corresponds to a 7-day compressive strength of 5,000 psi.

Mud Balance Diagram

Diagram of a laboratory balance scale, labeled with its nine main components: 1. Balance arm, 2. Bubble Level, 3. Cup, 4. Lid, 5. Counterweight, 6. Rider, 7. Base, 8. Knife Edge, and 9. Fulcrum.

Mud Balance Testing Procedure

  • Ensure Entire Assembly is Clean and Free of Any Residual Grout
  • Prepare Grout Mix Completely
  • Before Sending to Next Tank – Collect a Sample in the Cup of the Mud Balance
  • Once Lid is Placed – Grout Will Weep From the Hole in the Center. If Grout Does Not Weep Out of the Hole – Then the Cup is Not Sufficiently Filled
  • Thoroughly Clean Excess Grout From Exterior
  • Place Assembly in the Case. Use Pins to Guide Placement
  • Slide Scale Until Bubble Level Confirms It is Balanced
  • Detract Water From Mix Depending on Your Thickness Needs
