Question

the laboratory test data for a standard compaction test are given in the table below. draw and find maximum dry density and OMC.

volume(cm3) Moisture content (%) weight of wet soil (N)

943.3 12 15.20

14 16.06

16 16.58

18 16.83

20   16.66

Answer 1

Water Content (w) %	Wet Soil Weigth (Y) N
12	15.20	13.571
14	16.06	14.088
16	16.58	14.293
18	16.83	14.263
20	16.66	13.883

So From above table we can easily see that ...

We are getting Max dry density at water content of 16 %, Hence we get.....(ie OMC is that water content at which dry density is max)

Also we can find out this by Graphical Method ...So lets draw a graph between Water Content (w) and Dry Density (Y_d)  

So from the graph also we get ...
