HOW TO REDUCE CEMENT BALLING IN A MIXER TRUCK

Feb 02, 2016 · When the cement is being charged into the mixer truck, it should be feeding with the aggregate material and not water. By charging the mixer truck with 80% water, the aggregate in the mixer truck is below water level, and the incoming dry cement will skip across the water rolling and packing to the mixer blades.
