Importance of Sand Bulkage Test. If we need 1 m 3 of sand in concrete we need to know the approximate sand bulkage value. Say, for example, sample sand that we are going to use has 30% bulkage of sand then we need to take 30% more sand that is 1.3 times of sand while volume batching in order to get 1 m 3 of sand for concrete.
