Q: What does the Los Angeles abrasion test measure?
Solution:
The Los Angeles abrasion test measures the durability of aggregates by assessing their resistance to wear and degradation.
Steps: 7
Show Steps
Step 1: Understand that aggregates are materials like sand, gravel, or crushed stone used in construction.
Step 2: Know that the Los Angeles abrasion test is a laboratory test.
Step 3: The test involves placing a sample of aggregates in a rotating drum with steel balls.
Step 4: As the drum rotates, the aggregates are subjected to friction and impact from the steel balls.
Step 5: After a set amount of time, the aggregates are removed and their weight is measured.
Step 6: The amount of weight lost during the test indicates how much wear and degradation the aggregates experienced.
Step 7: A lower weight loss means the aggregates are more durable and resistant to wear.
