RESEARCH ON MIXING OF CONCRETE IN BATCH MIXERS

OBSERVATIONS AND TESTS WERE MADE TO LEARN MORE OF THE PROCESS OF MIXING OF CONCRETE AND TO FIND THE CHARACTERISTICS OF MIXERS AND THE EFFECT OF FEATURES OF DESIGN AND OPERATION UPON THE QUALITY OF THE PRODUCT. THE NEED OF FURTHER RESEARCH AND OF ENCOURAGEMENT OF INTEREST IN THIS FIELD AND THE NEED FOR ENGINEERS TO LEARN MORE ABOUT MIXING IS EMPHASIZED. BETTER SPECIFICATIONS FOR MAKING CONCRETE ARE SOUGHT. MIXING WAS DISCUSSED AS TO THE ACTION OF INTERMINGLING, INTIMATE MIXING, CHARGING AND DISCHARGING; ALSO, METHOD OF APPLYING WATER, TIME OF MIXING, AND SPEED OF ROTATION. COMMENTS ARE MADE OI THE DIMENSIONS AND VOLUME OF DRUM AND DRUM CAPACITY, EFFECT OF CONDITION OF INTERIOR OF DRUM, AND STANDARD METHOD OF TESTING CONCRETE. DISCUSSION WAS PRIMARILY RELATED TO THE MEASURING OF MIXING WATER, MIXING APPLIANCES, AND MIXING TIME.
