Yield of Concrete:
A volume of fully compacted concrete per bag of cement is known as yield of concrete.
Yield of concrete = 2 (volume of one bag of cement)/(3 + volume of per bag of cement aggregates in loose state used for one bag of cement).
The above formula gives approximate value of yield of concrete. Following methods may be used to obtain exact value of yield of concrete.
(a) Absolute volume method.
(b) Bulk density method.
