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. What are the Factors affecting the test results for specific gravity and water absorption?( 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:- Factors affecting value of specific gravity and water absorption of coarse aggregate:-

(1) Temperature

(2) Entrapped air in coarse aggregate

(3) humidity

(4) size of aggregate

(5) accuracy of apparatus

Specific gravity of coarse aggregate should be between 2.4 to 2.9
