• The whole test procedure shall then be examined and modified
as necessary to ensure that these requirements for range and
mean are satisfied.

• For satisfactory test runs the PSV of each sample shall be
calculated as follows.
• Calculate the mean value S of the recorded values of the four
test specimens (two from each run) and record to the nearest
0.1 unit.

• Calculate the mean value C of the recorded values of the four
control specimens (two from each run) and record to the
nearest 0.1 unit.

• Calculate the PSV from the following equation:

PSV = S + 52.5 – C

• NOTE This equation is valid only for values of C between 49.5

and 55.5

DISCUSSION : * Interpret and comment the results obtained

a If the PSV value results with different values, whether the decrease in alumina
. b. content will cause PSV weakening. Give a reason?
Give two experimentsfor polished stone value.

CONCLUSION
a. Give your conclusion from this experimental and explain the result you get.

REFERENCES: Give at least 5 references you refer
