Q. Can you implement Compatibility test ?
This test indicates the decrease in height of a mass of sand in a specimen tube with respect to its original height, under the action of blows. The test is important for sands used in moulding machines. The test is carried out on the sand rammer. The loose riddled sand is filled in the specimen tube. The sand is then compacted on the sand rammed by 3 blows of the weight. The percentage decrease in height is read on the scale.
