i know that, the for calculating material required for concrete volume of concrete is taken 50-54 % more for wet volume. i have querry is that cement and sand volume taken more for making wet volume but in the case of aggregate why it is taken more there is no change in aggregate whether it is dry or wet.???? can you give me answer for this???

Unit Weight and Compacted Density: Crushed glass has a unit weight of approximately 1120 kg/m 3 (70 lb/ft 3), which is lower than that of conventional aggregate. The compacted density of crushed glass will vary with the size and grading of the glass as well as the degree of contamination (extraneous debris, such as paper, plastic caps, and soil).
