Measurement of Aggregate Size and Shape Using Image

May 15, 2019Digital image analysis method has a potential to estimate the characteristics namely, the size and shape of aggregates rapidly and accurately. Two-dimensional image analysis of aggregate gives a relative idea of aggregate properties in a more accurate manner as compared to the procedure suggested in Indian standards.
