How to calculate corrected n value
WebThe MC is calculated as, MC= 100* (W - W dry) / W dry. where W is the weight at any point of time for which the moisture content has to be calculated and W dry is weight after drying. The equation ... WebThe effect of the water table is supposed to be already reflected in the measured blow count, but the correction N' = 15 + 1/2 × (N – 15) for submerged fine or silty sands should be applied for N > 15. In cases involving gravels or sandy gravels, the SPT blow count should be increased by a factor of about 1,25.
