Question
A box measuring is filled to the top with dry coarse aggregate of mass . The water absorption and specific gravity of the aggregate are and , respectively. The maximum quantity of water (in kg, round off to 2 decimal places) required to fill the box completely is ________
Correct answer
50.5 to 51.2
Solution
1.Volume of the box ():
2.Volume of solids ():
Given mass of dry aggregate and specific gravity . Assuming density of water :3.Volume of voids ():
4.Water required to fill the voids ():
5.Water absorbed by the aggregate ():
Water absorption is .6.Total water required:
Total water = Rounding to 2 decimal places, we get . This value falls within the accepted range of to .Continue learning with Success Tracker
