TEST 2 Specific gravity and water absorption of coarse aggre

TEST 2: Specific gravity and water absorption of coarse aggregate

MUST be based on the experimental data and need to be compared with the range of value from text/ publication.
3. how to minimize the errors?( I have attached the values of the test result)( Material:

3kg of coarse aggregate witha nominal size of 19mm was used) Any additional info required please let me know.. thank you

Solution

Answer:- methods for minimize errors of result:-

(1) By using correct temperature range for test.

(2) By removing entrapped air from coarse aggregate.

(3) By using correct size and shape of aggregate

(4) By using good quality apparatus for test

(5)By reducing human error during test

(6) By measuring correct weight of aggregate

(7) By using dry cloth for surface drying of aggregate
