5.2　Results of the tests

The results of the tests are given in Table 13.

　

Table 13　Results of permeability tests

Note 1: Hydraulic conductivity, i.e., coefficient on permeability, is calculated with the following formula:

k_T = (L・Q)/(h・A・t)

where, k_T: Darcy coefficient at temperature "T";

L: Height of specimen;

Q: Amount of water overflow in period "t";

h: Head;

A: Area of specimen; and

t: Period of measurement.

　

It can be said that the permeability of Nickel Slag is much higher than those of other materials tested and the permeability of Iron Conc. and Galena are higher than those of Copper Conc. and Zinc Conc., i.e., typical materials which may liquefy.
