PROBLEM TO BE SOLVED: To accurately measure a mass of aggregate and water considering surface water of the aggregate. SOLUTION: A method for measuring concrete material is provided wherein while the i-th (i=1, 2, 3...N) cast of the aggregate into a measuring tank is continuously or intermittently at a specific speed carried out, measurement of total mass Mfi (i=1, 2, 3...N) of the aggregate dipped in water is carried out in real time or at specific time intervals, and when total mass Mfj of the aggregate dipped in water in the j-th (i=1, 2, 3...N) aggregate reaches a target mass Mdj of the aggregate dipped in water at a point of time when the j-th cast of the aggregate ends, the j-th cast of the aggregate is stopped.
